| 20110261984 | HEARING AID WITH A CASING - A hearing aid is provided with a casing where to a battery drawer or lid is movably attached for movement between a closed position and an open position, where the open position grants access to a battery, wherein a leverage tool is removably fastened to the battery drawer. By way of the leverage tool, a hearing aid user with poor dexterity may now easily open the battery drawer. | 10-27-2011 |
| 20110026725 | METHOD FOR MONITORING THE INFLUENCE OF AMBIENT NOISE ON STOCHASTIC GRADIENT ALGORITHMS DURING IDENTIFICATION OF LINEAR TIME-INVARIANT SYSTEMS - A hearing aid system and a method of estimating ambient noise in a listening device includes an input transducer and an output transducer, an electrical forward path between the input transducer and the output transducer providing a forward gain, an electrical feedback path comprising an adaptive filter for estimating the acoustic feedback gain from the output transducer to the input transducer. A method determines the quality of a critical gain measurement for a listening device. The method comprises a) monitoring the energy of the first-difference of the filter coefficients of the adaptive filter over time and b) applying a predefined threshold criterion to the change in energy content from one time instance to another to determine an acceptable impact of the ambient noise. This technique may e.g. be used for the fitting of hearing instruments where background noise is variable. | 02-03-2011 |
| 20110002489 | HEARING AID SYSTEM COMPRISING A RECEIVER IN THE EAR AND A SYSTEM FOR IDENTIFICATION OF THE TYPE OF RECEIVER - The invention relates to a hearing aid system comprising a BTE-part adapted for being located at an ear of a user and an ITE-part adapted to be located in an ear canal of a user, the ITE-part comprising a receiver for converting an electric output signal comprising frequencies in the human audible frequency range to an output sound, the ITE-part further comprising a resistive ID-element. The invention further relates to a method and use. The object of the present invention is to provide a relatively simple scheme for identifying a receiver in a hearing aid system. The problem is solved in that the hearing aid system comprises a measurement circuit for measuring an ID-parameter indicative of the resistance of said resistive ID-element, wherein said measurement circuit is adapted to use said electric output signal to determine said ID-parameter. An advantage of the invention is that it utilizes the electric output signal used for driving the receiver (speaker). It does NOT require an additional signal, for example a DC voltage, in order to determine the ID-parameter. This reduces the complexity of the circuitry and/or the firmware running in the hearing instrument. Furthermore, the detection can be done anytime where an output signal is present in the hearing aid system. The invention may e.g. be used for listening devices comprising exchangeable receivers. | 01-06-2011 |
| 20090185704 | HEARING AID ADAPTED TO A SPECIFIC TYPE OF VOICE IN AN ACOUSTICAL ENVIRONMENT, A METHOD AND USE - A hearing aid having a microphone for converting an ambient sound signal to an electric sound signal, a voice detector adapted to determine if a voice is present in said electric sound signal and a frequency analyzer to determine a fundamental frequency of a voice present in said electric sound signal, a signal processor adapted to process said electric sound signal, or an electric signal derived from it, independent of adjustable processing parameters, a memory having corresponding sets of processing parameters and fundamental voice frequencies, a decision unit to select and forward from the memory to the signal processor a set of processing parameters in accordance with a fundamental frequency determined by the frequency analyzer. Further, a method of adapting a hearing aid and to the use of such hearing aid. | 07-23-2009 |
| 20090041275 | BEHIND THE EAR HEARING AID PART WITH EXCHANGEABLE COVER - The invention regards a BTE hearing aid shell shaped to fit behind an outer portion of an ear of a user wherein the shell has first and second opposed side walls where the first side wall faces away from, and the second side wall faces towards the head of the user. According to the invention an ornamental cover plate is detachably attached to at least one of the opposed side walls, and a release tool is provided for release of the cover plate. | 02-12-2009 |
| 20090041273 | BEHIND THE EAR HEARING AID PART WITH EXCHANGEABLE COVER - The invention regards a BTE hearing aid shell shaped to fit behind an outer portion of an ear of a user wherein the shell has first and second opposed side walls where the first side wall faces away from, and the second side wall faces towards the head of the user. According to the invention an ornamental cover plate is detachably attached to at least one of the opposed side walls, and a release tool is provided for release of the cover plate. | 02-12-2009 |
