20080232619 | Method for operating a hearing device - In the English translation document, please replace the abstract with the following: An unintentional adjustment of the user-controlled control elements on the device can result within the scope of the activation of a hearing device, after a switch-on delay has elapsed. To reduce this risk, a delay in the release of the user-controlled control elements attached to the device is provided in accordance with the invention in addition to the said switch-on delay. | 09-25-2008 |
20080240449 | Method and facility for reproducing synthetically generated signals by means of a binaural hearing system - Synthetically generated signals are reproduced via a binaural hearing system, which includes two hearing devices. After reproducing a first signal via the first hearing device a reproduction of a second signal via the second hearing device is also carried out delayed by a defined time interval. The additional time delay is to be quantified such that the impression of a sound amplification is produced with a hearing system wearer. | 10-02-2008 |
20080247577 | Method for reducing noise using trainable models - The object is to improve the effect of a noise reduction algorithm for hearing apparatuses and in particular hearing aids. This is achieved by a method wherein the input signal is modeled by a wanted signal model and a noise signal model. In addition, a signal statistic of the input signal is recorded in a data logging unit. The wanted signal model and/or the noise signal model can now be changed as a function of said signal statistic. Finally the noise component of the input signal is reduced using the noise signal model and/or the wanted signal model. This means that the models used can be continuously adapted to the hearing apparatus user's current situation. | 10-09-2008 |
20090046878 | Individually adjustable hearing aid and method for its operation - The invention relates to an adjustable hearing aid to which at least one parameter which influences the response and amplification characteristics of the hearing aid can be adjusted, with means being included which carry out testing of the effectiveness of an adjustment of this parameter in the prevailing auditory situation, and means being included which, given the existence of a minimum effectiveness, enable the adjustment option of this parameter. | 02-19-2009 |
20090252358 | Multi-stage estimation method for noise reduction and hearing apparatus - The noise reduction for signals which can contain speech at least part of the time is to be improved. To this end a hearing apparatus and especially a hearing device with a first estimation device for estimating a first value of an input signal with a first estimation algorithm and a noise reduction device for reducing noise in the input signal are provided. A second estimation device, which is parameterized with the estimated first value, is used for estimating a second value of the input signal with a second estimation algorithm. The noise reduction device receives the estimated second value from the second estimation device for reducing the noise. The two-stage estimation method enables an adaptive estimation to be carried out which is always currently adapted to an input signal. | 10-08-2009 |
20090290734 | HEARING APPARATUS WITH AN EQUALIZATION FILTER IN THE FILTER BANK SYSTEM - Multi-stage filter bank systems with filter banks of different bandwidth frequently cause interference in hearing apparatuses and in particular in hearing devices. Therefore a hearing apparatus is proposed with a filter bank system having a multi-stage analysis filter bank and/or a multi-stage synthesis filter bank, to break down an input signal of the hearing apparatus into a number of partial band signals by way of a number of filter bank channels and/or to recombine partial band signals of a number of filter bank channels. The filter bank system is equipped with at least one equalization filter, to equalize differences in the complex frequency responses between filter bank channels. It is thus possible in particular to equalize group delay time differences as well as attenuation and/or amplification | 11-26-2009 |
20100034407 | ARRANGEMENT AND METHOD FOR REGULATION OF FEEDBACK SUPPRESSION IN HEARING DEVICES - The invention specifies a hearing device, especially an in-the-ear hearing aid, and a method for suppressing acoustic feedback, with at least one ultrasound signal being emitted by the hearing device. The ultrasound signal reflected and fed back from the environment of the hearing device is picked up by at least one microphone and/or by at least one ultrasound receive unit of the hearing device. A feedback suppression unit of the hearing device is regulated by the picked up and evaluated ultrasound signal. The advantage of this is that feedback suppression in hearing devices can be regulated both quickly and also precisely. | 02-11-2010 |
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 |
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 |
