| 20120076335 | METHOD AND DEVICE FOR FREQUENCY COMPRESSION IN A HEARING AID - A hearing aid device suitable for executing a frequency compression is optimized to achieve a better assignment between channels of a source frequency range and channels of a target frequency range. A frequency range that can be transmitted by the hearing aid device is split into a number of frequency bands, after which a number of adjacent frequency bands are combined into at least one group of frequency bands and then one frequency band is selected from each group of frequency bands. The selected frequency bands are moved respectively into a target frequency band permanently assigned to the respective group. This prevents that a number of frequency bands from the source frequency range are shifted to the same target frequency band. | 03-29-2012 |
| 20120076333 | METHOD AND DEVICE FOR FREQUENCY COMPRESSION WITH SELECTIVE FREQUENCY SHIFTING - A method and device for frequency compression of audio signals to reduce the occurrence of artifacts. A component of the audio signal having a plurality of frequency channels is shifted from a first frequency channel into a second frequency channel. A dominant instantaneous frequency is determined in the first frequency channel. During shifting or mapping, first the entire first frequency channel, including the dominant instantaneous frequency, is shifted or mapped into the second frequency channel, wherein the dominant instantaneous frequency obtains an intermediate frequency position. A final frequency position for the dominant instantaneous frequency is determined using a predefined compression characteristic in the second frequency channel, starting from the frequency position of the dominant instantaneous frequency in the first frequency channel. Finally, the dominant instantaneous frequency is shifted or mapped from the intermediate frequency position to the final frequency position. | 03-29-2012 |

The method compresses the frequency of an audio signal having a fundamental frequency and at least one harmonic. The audio signal is provided in a plurality of frequency channels. The harmonic of the audio signal is shifted or mapped from a first frequency channel of the plurality of frequency channels into a second frequency channel. In addition a frequency which is likewise harmonic with respect to the fundamental frequency is estimated in the second frequency channel, the harmonic being shifted or mapped onto the estimated frequency. As a result the harmonic pattern is preserved in the compressed signal and the artifacts are reduced. | 03-29-2012 |
| 20120076331 | METHOD FOR RECONSTRUCTING A SPEECH SIGNAL AND HEARING DEVICE - Speech intelligibility is to be improved in hearing devices and in particular in hearing aids.

At least one matching portion and one non-matching portion of the predefined amplitude spectrum with respect to the amplitude spectrum of the input signal is detected. Finally the gain of the input signal in the non-matching portion of the amplitude spectrum is varied such that a closer match with the predefined amplitude spectrum is achieved compared to the original gain. | 03-29-2012 |
| 20120076313 | METHOD FOR ADJUSTING A HEARING DEVICE WITH IN-SITU AUDIOMETRY AND HEARING DEVICE - The adjustment of a hearing device is to be improved and configured in a more user-friendly fashion. To this end, a method is proposed whereby the hearing device is set individually to the user and is inserted at least partially into the auditory canal of the user. Finally an in-situ measurement of the acoustic impedance of the auditory system of the user including at least part of the auditory canal of the user is implemented with a tympanometric method.

A further change of state from the second state to the first state of the liquid can be caused by heating. | 03-22-2012 |
| 20120063621 | CONNECTOR FOR HEARING INSTRUMENT, HEARING INSTRUMENT AND HEARING INSTRUMENT SYSTEM - A connector for a hearing instrument has an electrical or acoustic connection component and a mechanical connection component. The electrical or acoustic connection component is brought into mutual engagement with an electrical or acoustic connection element inside a housing of the hearing instrument.

| 20120046713 | HEARING AID AND/OR TINNITUS THERAPY DEVICE - While prior art hearing aids and/or tinnitus therapy devices only contribute to making an existing tinnitus condition more bearable, the invention provides for a method for operating a hearing aid and/or tinnitus therapy device as well as a hearing aid and/or tinnitus therapy device which contributes to a tinnitus being able to be eliminated over the long-term. An acoustic output signal is generated in which the tinnitus frequency and/or the tinnitus frequency spectrum are suppressed. This makes the neuroplastic reorganization of the central auditory system of a sufferer possible, which reverses the tinnitus-causing maladaptive change in their central auditory system. | 02-23-2012 |
| 20120039496 | METHOD FOR REDUCING INTERFERENCE AND HEARING DEVICE - A method for operating a hearing device, which is embodied for wireless signal transmission of a data signal at a transmission frequency, provides an audio signal as a pulsed signal, in which a plurality of pulses fall within a predefined time slot. A frequency spectrum of the audio signal has a notch into which the transmission frequency is placed, and the pulses of the audio signal within the predefined time slot are shifted such that the energy of the frequency spectrum drops in the vicinity of the transmission frequency. | 02-16-2012 |
| 20120033840 | HEARING INSTRUMENT WITH AN INTEGRAL INJECTION-MOLDING CASING - A hearing instrument has an integral injection-molding casing. The hearing instrument fixes the internal components in an integral casing that is simple in design, production, and assembly; requires few components; and is easy to handle. Accordingly the hearing instrument contains an integral casing and a frame arranged within the casing. The casing has an assembly opening through which the frame is pushed into the casing. Additionally, the casing has a fixation opening oriented perpendicular to the insertion direction, which fixation opening interacts with a fixation device arranged on the frame in order to fix the frame in the casing. This provides a simple fixation mechanism. The fixation opening can be applied as a bore after the production of the casing, and so the casing has no undercuts and can therefore be produced in an injection-molding method. The fixation device can be embodied as a bolt. The bolt can be integrally molded onto the frame. The bolt can be inserted into the fixation opening by a spring force. In one embodiment, a microphone to be assembled after the frame has been inserted into the casing serves as a bolt. | 02-09-2012 |
| 20120033838 | HEARING INSTRUMENT WITH MECHANICAL AND REMOTE-CONTROLLABLE VOLUME ADJUSTMENT - A hearing instrument, e.g. a hearing aid, has a mechanical, manually actuated volume setting element and also remote control volume adjustment. The volume setting element is a control dial with a fixed assignment of the respective rotational position to a respective volume setting. An adjustment by remote control changes the volume setting but not the position of the control dial. This results in the problem that the normally fixed assignment of the respective position of the control dial to the respective volume setting no longer holds true. If there is once again an adjustment by control dial after the volume setting was changed by remote control and the volume prescribed by the control dial is then set, unpleasant jumps in volume may therefore occur. Such jumps in volume are avoided by the following steps: detecting a change in the rotational position of the control dial, establishing a current rotational position of the control dial during the change, comparing the current rotational position to a comparison rotational position, changing the volume setting of the hearing instrument in accordance with the current rotational position only if the current rotational position has, at least momentarily, assumed the comparison rotational position. | 02-09-2012 |
| 20120029268 | MAGNETOFLUIDIC HEARING AID SYSTEM AND HEARING AID - A magnetofluidic hearing aid system includes a hearing aid having a signal processing device connected to a magnetic transmitter. The system includes such a hearing aid and a magnetofluid suitable for use in the body. The magnetic transmitter transmits a magnetic field producing vibrations in a liquid mixture containing the magnetofluid. The liquid mixture is operatively introduced into a cochlea, and the vibrations are suitable for triggering an auditory perception in the cochlea. Acoustic feedback is precluded as a result of the transmitter producing neither acoustic signals nor mechanical vibrations. A functional impairment caused by physical influences such as soiling, for example, of an acoustic receiver, is also precluded. Problems arising from impaired contact with the body are prevented from the beginning by the non-contact signal transmission. A hearing aid supply is also advantageously enabled regardless of the functional capability of the middle ear apparatus. | 02-02-2012 |
| 20120020507 | HEARING AID AND IN-THE-EAR-DEVICE - A hearing aid may include a hearing aid housing. The hearing aid housing may include a first housing wall portion and a second housing wall portion. The first housing wall portion has a first flexibility, the second housing wall portion has a second flexibility and the first flexibility is different than the second flexibility. | 01-26-2012 |
| 20120008791 | HEARING DEVICE AND METHOD FOR OPERATING A HEARING DEVICE WITH TWO-STAGE TRANSFORMATION - A filter bank with a sufficiently high resolution for amplification and noise reduction and with the lowest possible computational complexity is provided for a hearing device and, in particular, for a hearing aid. Two-stage frequency transformation with little latency is therefore proposed for hearing aids. Some of the processing, for example the amplification, is carried out after high stopband attenuation in the first stage. An increased frequency resolution is achieved in a second stage before the back-transformation in the first stage, which is favorable for noise reduction, for example. | 01-12-2012 |
| 20120008790 | METHOD FOR LOCALIZING AN AUDIO SOURCE, AND MULTICHANNEL HEARING SYSTEM - Sound sources are reliably localized using a multichannel hearing system, in particular a binaural hearing system. The method localizes at least one audio source by detecting a signal in a prescribed class, the signal stemming from the audio source, in an input signal in the multichannel hearing system. The audio source is then localized using the detected signal. First, the nature of the signal is established over a wide band and then the location of the source is determined. | 01-12-2012 |
| 20120002831 | ELECTRICAL HEARING AID ADAPTER - An electrical hearing aid adapter is provided. The electrical hearing aid adapter may be configured to transfer programming data to a hearing aid having a first end portion formed in such a manner that it corresponds to the shape of a battery compartment receiving chamber being configured to receive a hearing aid battery compartment. The electrical hearing adapter may further include an interface configured to receive programming data and to transfer received programming data to an electrical contact portion arranged on the first end portion. The first electrical contact portion may be arranged such that it electrically contacts to a second electrical contact portion placed in the battery compartment receiving chamber, when the first end portion is inserted into the battery compartment receiving chamber. | 01-05-2012 |
| 20110307249 | METHOD AND ACOUSTIC SIGNAL PROCESSING SYSTEM FOR INTERFERENCE AND NOISE SUPPRESSION IN BINAURAL MICROPHONE CONFIGURATIONS - A method determines a bias reduced noise and interference estimation in a binaural microphone configuration with a right and a left microphone signal at a time-frame with a target speaker active. The method includes a determination of the auto power spectral density estimate of the common noise formed of noise and interference components of the right and left microphone signals and a modification of the auto power spectral density estimate of the common noise by using an estimate of the magnitude squared coherence of the noise and interference components contained in the right and left microphone signals determined at a time frame without a target speaker active. An acoustic signal processing system and a hearing aid implement the method for determining the bias reduced noise and interference estimation. The noise reduction performance of speech enhancement algorithms is improved by the invention. Further, distortions of the target speech signal and residual noise and interference components are reduced. | 12-15-2011 |
| 20110293125 | DEEP-EAR-CANAL HEARING DEVICE - A deep-ear-canal hearing device is worn deep in the ear canal of a user. The hearing device is easy to produce and use, has a small overall size, and can be comfortably worn deep within the auditory canal, in particular in the bony part of the auditory canal as well. The hearing device has a housing, a signal-processing apparatus, and a receiver. The signal-processing apparatus is arranged within the housing. The receiver is merely arranged partly within the housing and another part is arranged outside of the housing. The receiver only being arranged partly within the housing, it is thus not completely surrounded by the housing. Hence, the housing can have a smaller configuration. In the region where the receiver is arranged outside of the housing, the double wall in the form of, the receiver wall and, the housing wall can be dispensed with, which helps in reducing the size. | 12-01-2011 |
| 20110286616 | HEARING DEVICE WITH A PASSIVE UNIT SEATED DEEP IN THE AUDITORY CANAL - Hearing devices and, more particularly hearing aids, can be inserted into the auditory canal in an improved fashion. A hearing device has a first unit, which can be completely inserted within a human auditory canal. The first unit has a first housing into which a sound-recording element, a receiver and, connected therebetween, an amplifier are integrated. The hearing device moreover has a second unit, which is outside of the first housing and can be inserted into the human auditory canal in addition to the first unit. The second unit is galvanically connected to the first unit and configured for wireless energy absorption and for supplying the first unit with current. Hence, the first unit, together with the second unit, does not require a battery as an energy source and can thus have a smaller configuration, and therefore it can optionally be introduced further into the auditory canal. | 11-24-2011 |
| 20110268304 | HEARING AID WITH EAR-HOOK SAFETY MECHANISM - Children should be prevented from easily being able to remove the ear hook of a hearing aid. It is for this reason that a hearing aid that is to be worn behind an ear has a housing, which houses signal-processing components, and an ear hook, which is detachably attached to the housing. During the attachment process, the ear hook is moved toward the housing in an axial direction. The ear hook and the housing are embodied such that, in order to attach the ear hook to the housing, there is at least one movement of the ear hook in a second direction and a movement of the ear hook in a third direction, which differs from the second direction. Both the second and the third direction differ from the first direction. It follows that a complicated movement pattern is required when the ear hook is disassembled from the housing. | 11-03-2011 |
| 20110268302 | HEARING AID - A hearing aid contains a hearing aid housing having a receiving portion and a support structure positioned within the hearing aid housing. The support structure contains a substrate having an electronic circuit and a support member coupled to the substrate. The support member is configured to be adhered to the substrate, and the support structure is coupled to the receiving portion. | 11-03-2011 |
| 20110249848 | HEARING AID WITH AUDIO SHOE - The invention relates to a hearing aid with an audio-shoe interface, an associated audio shoe and a hearing-aid system comprising a hearing aid and an audio shoe. A basic idea of the invention consists of a hearing aid with a housing, in which an undercut and an abutment are provided. The abutment is arranged opposite to the undercut. Undercut and abutment are embodied such that a retaining lug of an audio shoe can be inserted into the undercut by a rotational movement. The abutment is embodied such that a retaining lug inserted into the undercut can only be removed from the undercut again by a rotational movement in the opposite direction. Furthermore, provision is made for a lock that prevents a rotational movement of an inserted audio shoe in the opposite direction. When the electrical contacts between audio shoe and hearing aid are disposed in the undercut, these too are hidden from view and well protected against external influences. | 10-13-2011 |
| 20110243339 | DUAL SETTING METHOD FOR A HEARING SYSTEM - The perception of musical sound with a music component and a speech component is intended to be improved. To this end, a method is proposed for controlling a binaural hearing system with a left hearing-device for a left ear and a right hearing-device for a right ear, which method contains the below described steps. First of all, the hearing system determines a hearing situation with the music component and the speech component. Thereupon, one of the two hearing devices is switched into a music mode and, at the same time, the other one of the two hearing devices is switched into a speech mode. The hearing-aid wearer himself/herself can then decide which component of the sound he/she would rather listen to. | 10-06-2011 |
| 20110238419 | BINAURAL METHOD AND BINAURAL CONFIGURATION FOR VOICE CONTROL OF HEARING DEVICES - A binaural configuration and an associated method have/utilize first and second hearing devices for the voice control of the hearing devices by voice commands. The configuration contains a first voice recognition module in the first hearing device and a second voice recognition module in the second hearing device. The second voice recognition module uses information data from the first voice recognition module for recognition of the voice commands. It is here advantageous that the rate of erroneously recognized voice commands (“false alarms”) is reduced. | 09-29-2011 |
| 20110235837 | HEARING AID WITH AMORPHOUS LOUDSPEAKER SHIELDING - It should be possible to produce hearing aids in a simpler and more compact fashion. It is for this reason that a hearing aid is proposed, the loudspeaker device of which is shielded by a shielding device, more particularly a housing ( | 09-29-2011 |
| 20110235836 | METHOD FOR THE TRANSMISSION OF DATA BETWEEN A HEARING DEVICE AND AN EXTERNAL UNIT, AND ASSOCIATED CONFIGURATION - A method and an associated configuration transmit data between a hearing device and an external unit. A first data packet is transmitted to the hearing device by the external unit. The first data packet is received by the hearing device and a second data packet is transmitted from the hearing device to the external unit. A predefinable fixed period of time elapses between the end of the receipt of the first data packet and the start of transmission of the second data packet. The external unit thereby “knows” when the first bit of the second data packet is to arrive. This offers the advantage that the reliability of a data transmission is improved. In the case of a packet-oriented data transmission fewer data packet repetitions are required, as a result of which the transmission speed increases. | 09-29-2011 |
| 20110233783 | SUBSTRATE ARRANGEMENT - In an embodiment, a substrate arrangement is provided. The substrate arrangement may include a semiconductor substrate including a first contact portion and a second contact portion on a first surface of the semiconductor substrate, wherein the semiconductor substrate is arranged such that the first contact portion and the second contact portion face each other. The substrate arrangement may further include an electrical connector configured to connect the first contact portion and the second contact portion. | 09-29-2011 |
| 20110228961 | HEARING DEVICE AND METHOD FOR PRODUCING AN OMNIDIRECTIONAL DIRECTIONAL CHARACTERISTIC - A hearing device is provided with a microphone array having a plurality of microphones. The signals from the microphones can then be processed by an appropriate apparatus of the hearing device such that this results in a directivity of the microphone array. The apparatus must also be able to allow an omnidirectional directivity of the microphone array, i.e. a non-directional detection of sound. This is not always ensured in the case where one of the microphones in the microphone array is covered or aligned other than what is intended. An omnidirectional directivity of the microphone array is ensured in a hearing device of the invention. Here, the microphones are, for this purpose, connected to inputs of the apparatus via a coupling device, by way of which each of the microphones can be coupled to a plurality of inputs of the apparatus at the same time. | 09-22-2011 |
| 20110228960 | HEARING DEVICE AND METHOD FOR SETTING THE HEARING DEVICE FOR FEEDBACK-REDUCED OPERATION - Sound from the receiver of a hearing device may be fed back to its microphones via acoustic feedback paths, which may cause undesirable whistling. It is particularly difficult to predict the creation of feedback in a microphone array with adjustable directional characteristic. This is because the stability of the system then is dependent on a directional parameter by way of which the directional characteristic is fixed. The invention enables feedback-free operation of such a hearing device. A prescribed stability condition is used to establish for which values of the directional parameter feedback-free operation is possible. The directional parameter is then restricted to these values during operation of the hearing device. As an alternative thereto, a value for a strength of a feedback effect is established for a current value of the directional parameter and the directional parameter or a control parameter for the purpose of feedback suppression is then set as a function of the established value. | 09-22-2011 |
| 20110222716 | HEARING AID HOUSING - In an embodiment, a hearing aid housing is provided. The hearing aid housing may include a first behind-the-ear hearing aid housing portion, a second behind-the-ear hearing aid housing portion, and a moisture protector at least partially arranged between the first behind-the-ear hearing aid housing portion and the second behind-the-ear hearing aid housing portion. | 09-15-2011 |
| 20110219879 | HEARING-TEST METHOD - The usefulness and sensitivity of a hearing-test method that can be performed over the Internet should be improved. To this end, it is proposed that meaningless syllables, so-called logatomes, are presented to a test person in fluctuating interference noise. Hence, the test can be offered internationally without change and there is no need to calibrate a computer used by the test person. | 09-15-2011 |
| 20110211718 | HEARING AID - In an embodiment, a hearing aid ( | 09-01-2011 |
| 20110211716 | HEARING DEVICE WITH A CONDUCTING ELEMENT, IN PARTICULAR A SOUND TUBE - In a hearing aid provision can be made for a housing that is worn outside of an auditory canal of a user. Then, sound or electrical signals are conducted into the auditory canal from the housing. To this end, provision can be made for a conducting element such as a sound tube or a cable. The conducting element is then connected to the housing via a coupling element. This connection must be embodied such that the coupling element does not detach from the housing on its own accord. The user must be able to remove the coupling element and the conducting element from the housing in a simple fashion in order e.g. to be able to clean the former two parts. Accordingly, a coupling element and a housing can be interconnected in a detachable fashion, with this connection containing a dovetail joint for the hearing aid. | 09-01-2011 |
| 20110211715 | HEARING DEVICE WITH FEEDBACK-REDUCTION FILTERS OPERATED IN PARALLEL, AND METHOD - A hearing device has a signal-processing apparatus for processing an input signal into an output signal, and a feedback-canceller apparatus for reducing feedback artifacts on the basis of the input signal and the output signal. The feedback-canceller apparatus has an adaptive, first filter, for establishing a set of filter coefficients for a predefined feedback situation. The feedback-canceller apparatus is configured to store the set of filter coefficients. It has at least one second filter, which can be operated directly parallel to the first filter on the basis of the stored set of filter coefficients. The adaptive, first filter can be continuously adapted to a current feedback situation, and the feedback-canceller apparatus is configured such that in the current feedback situation it automatically selects either the first or the second filter. As a result, it generally only requires a simple switchover, but not a complete adaptation. | 09-01-2011 |
| 20110207094 | METHOD FOR TRAINING SPEECH PERCEPTION AND TRAINING DEVICE - The speech perception of hearing-aid wearers and wearers of other hearing devices is intended to be improved. To this end, a method for training the speech perception of a person, who is wearing a hearing device, is provided, in which a first speech component is presented acoustically and the latter is identified by the person wearing the hearing device. Subsequently, there is automated modification of the acoustic presentation of the presented speech component and the aforementioned steps are repeated with the modified presentation until, if the identification is incorrect, a prescribed maximum number of repetitions has been reached. Otherwise, if the first speech component is identified correctly or if the number of incorrect identifications of the first speech component is one more than the maximum repetition number, a second speech component is presented acoustically. This allows a plurality of speech components to be trained in respectively a number of steps. | 08-25-2011 |
| 20110206227 | DEVICE FOR INSERTING A PIN INTO A HEARING AID - A device for inserting a pin into a hearing aid has a gripper embodied in the shape of a cylinder. In an end face the gripper has an aperture by way of which a pin that is to be placed in the hearing aid is picked up. For this purpose the gripper is pressed onto the pin. After the pin has been successfully placed in the hearing aid, pressure is then applied, by squeezing with the hand for example, to the lateral surface of the gripper. This causes a size of the aperture to be changed in the radial direction, as a result of which the pin clasped by the gripper is released. By this means it is advantageously possible to pick up a pin that is to be placed in the hearing aid and install it while making use of only one hand and without recourse to a tool such as a pair of tweezers, for example. | 08-25-2011 |
| 20110194718 | RECEIVER TUBE WITH STRAIN RELIEF AND HEARING AID - A receiver tube for a hearing aid has an integrated strain relief. A receiver mounted at the end of the receiver tube is normally worn in the auditory canal of a hearing aid wearer. It is pulled out of the auditory canal by pulling at the receiver tube or also separated from the receiver tube for the purpose of cleaning or exchange. Due to the tensile forces, the flexible receiver tube is stretched and elongated. This longitudinal extension may under certain circumstances amount to up to several millimeters and load or even damage the connection of the less extensible conductor to the receiver or to the hearing aid extending through the receiver tube due to tension. The novel receiver tube has a strain relief with a strain aid that is inexpensive to produce and benefitting a small diameter, has a high visual transparency and a high flexibility of the receiver tube. The receiver tube has a flexible sheathing and an electrical conductor extending through the sheathing and longitudinally displaceable therein relative to the sheathing. Without any tensile loading in the longitudinal direction, a longitudinal section of the conductor lying within the sheathing has a greater length than the longitudinal section of the sheathing surrounding it, and this longitudinal section of the conductor is freely movable transversely to the longitudinal direction within the longitudinal section of the sheathing. | 08-11-2011 |
| 20110194716 | HEARING DEVICE WITH A DETACHABLY COUPLED EARPIECE - In a hearing device or hearing aid, provision can be made for a sound tube or an in-the-ear loudspeaker to be held in an auditory canal of a user by an earpiece. To couple a sound tube to an earpiece, a connection element can be provided on the sound tube, which connection element can be connected to a connection element for the earpiece. This connection must be detachable so that a user can remove the earpiece from the sound tube. Nevertheless, it must be possible to transmit such a large force over the connection that the earpiece can once again be pulled out of the auditory canal. The object is to simplify a detachable connection for coupling an earpiece to a sound tube or an in-the-ear loudspeaker. Accordingly, the connection element for the earpiece is provided as an independent component, which is attached in or on the earpiece. | 08-11-2011 |
| 20110194715 | METHOD FOR COMPENSATING FOR A FEEDBACK SIGNAL, AND HEARING DEVICE - Feedback in a hearing device and, more particularly, in a hearing aid should be compensated for before it becomes audible. To this end, a method is proposed for compensating for a feedback signal in a hearing device with an input-transducer apparatus, a signal-processing apparatus and an output-transducer apparatus, in which method a feedback signal is compensated for, which feedback signal is fed back to the input-transducer apparatus from the output-transducer apparatus or the signal-processing apparatus. More particularly, a probability of having a plurality of notches, equally spaced apart from one another, in the spectrum of an input signal is established, which input signal originates directly from the input-transducer apparatus or which is a difference signal between the signal directly from the input-transducer apparatus and a compensation signal serving for compensation. The compensation is modified or the signal-processing apparatus is amplified as a function of this established probability. | 08-11-2011 |
| 20110194714 | HEARING DEVICE WITH FREQUENCY SHIFTING AND ASSOCIATED METHOD - A hearing device has a feedback suppression unit. The hearing device further has a low-pass filter characterized by a first cut-off frequency, which couples out a low-frequency signal component from an output signal of the hearing device, and a high-pass filter characterized by a second cut-off frequency, which couples out a high-frequency signal component from the output signal of the hearing device. A frequency shift unit shifts the frequency of the high-frequency signal component to higher frequencies. A gap exists between the first and the second cut-off frequency. As a result of the different limit frequencies, signal distortions caused by frequency shifts are effectively suppressed. Feedback is suppressed continuously and rapidly at higher frequencies. | 08-11-2011 |

Nevertheless, the connection between the tube and the earpiece is made detachable by an appropriate plug so that the earpiece can be cleaned. The plug is attached as securely as possible to the soft tube. One end of the tube and a region of the plug may be encapsulated by a material by insert molding or the tube and the plug may be welded together.

The method includes connecting a first electrical connection of the microphones to one another in order to form a first signal with directional effect, an adjustment of the directional effect of the first signal such that the acoustic feedback in the first signal is maximized, and an analysis of the first signal by the detection unit for defining the acoustic feedback. It is advantageous that the feedback can be detected by a signal with an improved signal-to-noise ratio. Feedbacks are therefore recognized more reliably and more rapidly. | 06-23-2011 |
| 20110142271 | METHOD FOR FREQUENCY TRANSPOSITION IN A HEARING AID AND HEARING AID - In a hearing aid offering the option of frequency transposition, sounds should still be perceivable as sounds, even after the frequency transposition. To this end, it is proposed first of all to establish sounds present in the input signal and, more particularly, the fundamental frequencies thereof and to carry out the frequency transposition as a function of the established fundamental frequencies. Here, transposed overtones are returned to the frequency grid of the fundamental frequency, and so the sound property is maintained even after the frequency transposition. | 06-16-2011 |

| 20110103611 | HEARING DEVICE AND METHOD FOR SUPPRESSING FEEDBACK WITH A DIRECTIONAL MICROPHONE - A hearing device and an associated method use an adaptive directional microphone for suppressing feedback. The hearing device includes an adaptation unit which sets the directional microphone so that a sound signal fed back from an earpiece of the hearing device to the directional microphone is attenuated. Acoustic feedback is advantageously attenuated or suppressed simply in an artifact-free manner. | 05-05-2011 |
| 20110077760 | METHOD OF PRODUCING A HOUSING SHELL OR EAR MOLD TO BE WORN IN THE EAR - The production of a hearing aid housing shell or ear mold that can be worn in the ear should be simplified and improved. For this, a prefabricated component, such as a frame for holding an electronics module or a receiver adapter, is positioned in a rapid prototyping instrument. There, the component is integrated into the housing shell or ear mold by the subsequent production of the housing shell or ear mold. This avoids connecting the component to the housing shell or ear mold in a further method step after producing the housing shell or ear mold. | 03-31-2011 |

The unlocking arrangement deactivates the locking arrangement only during and/or in a limited time period following simultaneous manual actuation of the sensors. The spatially separate arrangement of the sensors can suppress an accidental undesired actuation. | 03-03-2011 |
| 20110051964 | SELF-ADJUSTMENT OF A HEARING AID AND HEARING AID - The adjustment of the signal processing carried out by a hearing aid to the individual hearing loss of a user is intended to be simplified.

| 20110051963 | METHOD FOR FINE-TUNING A HEARING AID AND HEARING AID - The fine-tuning of the signal processing in a hearing aid or hearing aid system to the individual user should be simplified and improved. For this, the current hearing situation is recognized automatically and the user is automatically presented with a selection of questions from a comprehensive list of questions as a function of the hearing situation. A user input as a reaction of the user to the selected questions leads to the tuning of at least one parameter relating to the signal processing in the hearing aid. | 03-03-2011 |
| 20110051943 | METHOD FOR ADJUSTING A HEARING AID AND HEARING AID ADJUSTMENT INSTRUMENT - Optimized hearing aid parameter settings are automatically determined from a multiplicity of data obtained by applying different test methods for testing the auditory perception of a person. Data pertaining to the auditory perception (audiological data) of the user are first obtained by different test methods. The data from the individual tests can be incomplete, inconsistent or untypical, or even erroneous. However, the subsequent combination of where possible all available data in a computational unit affords the possibility of automatically obtaining hearing aid parameter settings by way of which a hearing aid operated thereby compensates the present loss of hearing of the relevant user in an optimized fashion. | 03-03-2011 |

The screen is attached by the first opening to a body of the cavity examination device on a side of the cavity examination device, which is inserted first into the cavity. During insertion of the cavity examination device into the cavity, the screen is folded in the direction of the cavity examination device, and as the cavity examination device is moved out of the cavity, it folds over so that the screen is folded away from the cavity examination device as the cavity examination device is removed from the cavity. | 02-24-2011 |
| 20110038500 | HEARING AID WITH LED AND METHOD OF OPERATION - A hearing aid has a housing, a signal-processing arrangement housed in the housing, an LED, an actuatable switching element arranged on the housing, and a battery. The LED is connected to a positive pole of the battery with its anode connector and to a first connector of the signal-processing arrangement with its cathode connector.

The structural element is a valve formed with electroactive material and the size of the through-opening is adjusted by application of a voltage to the valve. | 01-27-2011 |
| 20110019850 | HEARING AID - In an embodiment, a hearing aid is provided. The hearing aid may include a behind-the-ear component, a sound tube coupled with the behind-the-ear component at its one end, and a loudspeaker coupled with the sound tube at the other end of the sound tube opposite to the behind-the-ear component.

The electrical signal is transmitted from the wireless transmitter to the wireless receiver wirelessly. The electrical signal may be transmitted by induction. The transmitter seal and the receiver seal prevent any environmental influences from acting on the hearing aid device and thus protect the hearing aid device from malfunctioning or becoming short circuited. Magnetic connectors and/or mechanical connectors are provided for a stable contact between the processing unit and the receiving unit. | 01-27-2011 |
| 20110013797 | HEARING AID WITH AN INTERCHANGEABLE EARPIECE - A hearing aid has an interchangeable earpiece, which, on its own and separately from further components, can be replaced in a simple fashion and without great complexity, and without specialist tools. The hearing aid has a housing of a multi-part design and a receiver and a signal processing device within the housing. The receiver is arranged detachably in a first housing part and the signal processing device is disposed in a further housing part and the two housing parts are detachably interconnected. A detachable locking mechanism connects the housing parts. The receiver is connected to the signal processing device by way of a detachable electrical connector with a receiver-side and a signal-processing-device-side electrical contact. At least one of the electrical contacts is elastic. Due to the fact that the housing parts, the electrical connection and the receiver are detachably assembled, this results in the possibility of, when necessary, interchanging the receiver on its own, separately from further components. It is not necessary to use specific components or even an adhesive. In the process, the elastic electrical contact for electrically connecting the receiver and signal processing device makes it easier to close the electrical connection when assembling the housing parts. | 01-20-2011 |
| 20110013796 | RECEIVER TUBE, RECEIVER AND HEARING AID INSTRUMENT WITH A RECEIVER TUBE - A receiver tube for connecting a receiver to a hearing aid instrument and a hearing aid instrument with a receiver tube, include a connection which ensures good acoustic stability and low feedback tendencies, can be produced in an uncomplicated manner and has high impact and shock strength. The receiver tube includes a receiver connector constructed as a cup at least partly holding a receiver when connected together. The receiver connector includes a form-locking mechanism for a receiver and a flexible element for locking the receiver. The form-locking connection simplifies installation of the receiver during production or replacement by requiring neither application of a force, as when pretensioning or expanding force-locking connections, nor establishment of an adhesive connection. The locking mechanism can be opened/closed by the flexible element. The cup-shape of the receiver connector contributes to increased rigidity and reliability of the form-locking connection to the receiver and an acoustic shield. | 01-20-2011 |
| 20110013793 | VOLUME ADJUSTER AND HEARING AID WITH VOLUME ADJUSTER - A manually-actuatable volume adjuster for a hearing aid and a hearing aid with the volume adjuster are user friendly, durable, hardly prone to errors, miniaturizable and energy-saving.

The infrared sensor is only activated while the pushbutton switch is actuated and/or during a restricted time period following that actuation. The hearing aid with the adjuster includes standard sensors as an infrared sensor and as a pushbutton switch. The infrared sensor permits construction of the adjuster without moveable mechanical actuating elements and avoids touch surfaces or contact surfaces susceptible to wear-and-tear. The increased energy consumption of an infrared sensor is counteracted by the functional combination with the pushbutton switch. The infrared sensor is only active when the pushbutton switch is actuated and is otherwise in idle mode. | 01-20-2011 |
| 20110007918 | FILTER BANK CONFIGURATION FOR A HEARING DEVICE - A filter bank configuration for a hearing device has filters in an analysis filter bank and corresponding filters in a synthesis filter bank that are coupled pair-wise to form a channel in each case. In order to compensate for a hearing loss, sub-band signals are amplified in the individual channels with the aid of multipliers. In the process, an audible distortion of an output signal Y of the filter bank configuration as a result of differences between amplification factors of the multipliers of neighboring channels should be prevented. Here, at least one channel changes a phase of a sub-band signal transmitted by the channel such that a difference between a group delay of the filter bank configuration and a prescribable reference value is reduced for at least one predetermined frequency. The filter bank configuration is particularly suited to hearing aids. | 01-13-2011 |

A hearing aid appliance having such a housing shell is also provided as well as a method for producing such a housing shell for which a rapid-prototyping process is employed and by which the recesses are produced by not solidifying the starting material there. | 01-06-2011 |
| 20100329493 | HEARING APPARATUS AND METHOD FOR SUPPRESSING FEEDBACK IN A HEARING APPARATUS - A hearing apparatus and an associated method for suppressing feedback include a microphone emitting a microphone signal and a receiver picking up a receiver signal by subtracting a compensation signal from the microphone signal. The hearing apparatus includes a number of preset static first compensation filters for forming first compensation signals from the receiver signal and a first selection unit, which selects a first compensation signal in such a way that a feedback signal caused by the feedback is minimal in the receiver signal.

| 20100296681 | HEARING DEVICE WITH A SOUND TRANSDUCER AND METHOD FOR PRODUCING A SOUND TRANSDUCER - In hearing devices, more particularly in hearing aids, it is desirable to be able to design an earpiece for generating sound in the audible range which is as small as possible. Such an earpiece can then be worn comfortably on an ear or in an auditory canal. A sound transducer for the hearing device disclosed here may be formed as a micro-electromechanical system and the transducer enables generation of an acoustic signal with little distortion. Provision is made for a hearing device with a sound transducer, which has a field generation apparatus for generating an electric or magnetic field and an emission apparatus for generating sound.

The energy for the supply of the first transponder is delivered by the carrier signal of the external unit. | 11-04-2010 |
| 20100272289 | METHOD FOR OPERATING A HEARING APPARATUS AND HEARING APPARATUS WITH A FREQUENCY SEPARATING FILTER - A method operates a hearing apparatus. The hearing apparatus contains a frequency separating filter characterized by a threshold frequency, which splits an input signal into a low-frequency signal component and a high-frequency signal component.

| 20100266152 | METHOD AND ACOUSTIC SIGNAL PROCESSING DEVICE FOR ESTIMATING LINEAR PREDICTIVE CODING COEFFICIENTS - A method and an appropriate acoustic signal processing device estimate a set of linear predictive coding coefficients of a microphone signal using minimum mean-square error estimation with a codebook containing several predetermined sets of linear predictive coding coefficients. The method includes determining sums of weighted backward transition probabilities describing the transition probabilities between the predetermined sets of linear predictive coding coefficients. The backward transition probabilities are obtained from signal training data by mapping the signal training data to one set of the codebook and by determining relative frequencies of transitions between two of the sets of the codebook. Modelling the “memory” of the codebook has the advantage that the accuracy of estimating linear predictive coding coefficients is increased considerably also for speech components. | 10-21-2010 |
| 20100260368 | HEARING DEVICE WITH BATTERY FLAP MODULE - Shells of hearing devices, and in particular for hearing aids, are frequently manufactured using an RSM method and battery flaps are injection-molded. Problems arise frequently due to the varying error tolerances of the two processes when the battery compartment is locked into position on the shell. For this reason a hearing device with a shell, which has a battery opening and a battery flap, which is injection-molded from plastic, is provided for closing the battery opening. The hearing device also has a module which is likewise injection-molded from plastic, on which the battery flap is pivotally supported and which has a detent mechanism via which the battery flap locks into place detachably in a closed position to prevent a pivot movement. Since the injection-molded battery flap locks into position with the injection-molded module, the error tolerances of the shell, often produced by an RSM method, play no part. | 10-14-2010 |
| 20100260366 | Hearing Aid with a Battery Compartment, and Battery Compartment for a Hearing Aid, each having a Locking Mechanism for the Battery Compartment - A hearing aid has a housing, a battery compartment, and a locking mechanism for the battery compartment. A shaft which is arranged on the housing or the battery compartment, and a slide having a hole which forms a fit with the shaft, such that the slide can be moved on the shaft in order to lock and unlock the battery compartment in the housing. The hole has a circular cross section, and the shaft has a cross section which is not a circle, with rotational symmetry when rotated through 360°/n, where n is an integer greater than 1. A battery compartment for a hearing aid has a locking mechanism such as this. Because a cross section of said shaft is different from the cross section of the hole in the battery compartment, the shaft is connected to the hole in the battery compartment only at a number of points. This ensures that the slide is held adequately on the shaft even in the event of a production tolerance on the one hand, while, on the other hand, the slide can move on the shaft with little resistance. In a preferred embodiment the shaft is trilobular in cross-section. | 10-14-2010 |

The configuration additionally contains at least one second antenna disposed in the lanyard and at least one third antenna arranged in the lanyard which is connected by an electric series circuit to the second antenna. The advantage of this is that the lanyard can be made long enough to be comfortable to wear and a sufficiently high receive signal of the wireless data transmission is still guaranteed in the external unit. | 10-07-2010 |

The hearing aid user is able to evaluate and change the setting of their hearing aid retrospectively for specific hearing situations. | 10-07-2010 |
| 20100254538 | METHOD FOR LOUDNESS-BASED ADJUSTMENT OF THE AMPLIFICATION OF A HEARING AID AND ASSOCIATED HEARING AID - A method and an associated hearing aid for loudness-based adjustment of the amplification of the hearing aid by presenting test signals of a predefinable level and predefinable frequency. Blind signals are presented before and between the test signals, but the blind signals are not taken into account for the adjustment of the amplification of the hearing aid at the predefinable level and predefinable frequency.

| 20100246868 | METHOD FOR OPERATING A HEARING APPARATUS WITH AMPLIFIED FEEDBACK COMPENSATION AND HEARING APPARATUS - The goal is to make insertion of a hearing apparatus in an ear more comfortable, in particular with respect to feedback whistling. A method for operating a hearing apparatus by amplifying an input sound to form an output sound and compensating by a predefined amount for feedback caused by the output sound is therefore provided. In a predetermined period after switching on the hearing apparatus, the amount of feedback compensation is automatically increased by an offset greater than zero compared with the predefined amount.

The directional characteristic of the microphone system is adjusted in dependence on the determined characteristic of the microphone signal.

| 20100232622 | METHOD FOR COMPENSATING FOR AN INTERFERENCE SOUND IN A HEARING APPARATUS, HEARING APPARATUS, AND METHOD FOR ADJUSTING A HEARING APPARATUS - A novel system prevents surrounding sound to enter through a hearing apparatus, for instance through a ventilation opening, and reach an eardrum of the wearer in the form of interference sound. Contrary to auditory accessories designed especially to protect against noise, it is not possible for many hearing apparatus to compensate for such an interference sound by means of active noise cancellation. The hearing apparatuses do not have the special components needed. No compensation sound signal can therefore form with a correct phase. In accordance with the invention, a compensation sound is only generated for a relatively narrow spectral band. This spectral band is determined as a function of a hearing ability of the wearer of the hearing apparatus and/or as a function of a spectral distribution of the energy of the interference sound or a sound producing the interference sound. The improvement is particularly suited to compensating for an interference sound in a hearing device. | 09-16-2010 |

To estimate the background noise, the level of an output signal from the first and/or the second directional microphone having a monaural directional characteristic is combined with the level of an output signal from the directional microphone having a binaural directional characteristic. Background noise estimation is thereby enhanced in the case of binaural supply. | 08-19-2010 |
