摘要： A method performs synchronous access between a first communication device and a second communication device. The first communication device adopts N frequency hopping channels and performs frequency hopping in a predetermined frequency hopping sequence and at a predetermined frequency hopping time interval. The first communication device sends a broadcast beacon over the N frequency hopping channels with a cycle of M times the predetermined frequency hopping time interval. The broadcast beacon carries general information including synchronization information. M and N are both natural numbers. The second communication device receives the broadcast beacon over any one frequency hopping channel of the N frequency hopping channels to acquire the synchronization information. The second communication device exchanges information with the first communication device for access. This flexible, simple and easy-to-implement synchronous access solution achieves high-efficiency utilization and good anti-interference of a bandwidth, and allows rapid and reliable synchronization with low power consumption.

摘要： Hearing apparatuses, in particular hearing aids, have improved intelligibility. This is accomplished by a method for amplifying a speech signal for a hearing apparatus by detection of an input sound, determining an input level of the input sound and amplification of the input sound. A mean input level of the input sound is determined and it is established whether the input sound has a speech component. If not, the input signal is amplified in dependence on the input level in accordance with a predefined first amplification characteristic. However, if a speech component is found, the input signal is amplified in dependence on the input level in accordance with a predefined second amplification characteristic. The second amplification characteristic is formed in dependence on the mean input level such that amplification is increased with respect to first amplification characteristic in a predefined level interval below the mean input level.

摘要： 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.

摘要： 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.

摘要： Acoustic feedback in an audio device is reduced or eliminated via a feedback compensator. The feedback compensator disposes of at least one adaptive filter whose adaptation is governed by a step-size parameter p. A step-size parameter p of the adaptive filter is set at a high level to eliminate acoustic feedback and the parameter p is decreased when a critical excitation signal is detected. This way to proceed allows for efficient elimination of feedback whistling while required environment signals are retained.

摘要： A method for the operation of a hearing device with at least one receiver includes carrying out a fixed second frequency shift of an electrical receiver signal supplying the receiver or of a predefinable frequency range of the receiver signal and a variable first frequency shift of the receiver signal or of a predefinable frequency range of the receiver signal. The first frequency shift is changed depending on the occurring feedback. A frequency shift which effectively prevents feedback is advantageously carried out, while artifacts of the frequency shift are minimized.

摘要： A hearing aid device has an input converter for receiving an input signal and converting the signal into an electrical input signal, a signal processing unit for processing and frequency-dependent amplification of the electrical input signal and generating an electrical output signal, an output converter for converting the electrical output signal into an acoustic output signal, and a sound detector facility for identifying sounds in a signal. Facilities increase an amplification above a normal amplification for a frequency range in which an identified sound contains signal components. Further facilities set the normal amplification of an electrical input signal in dependence on a signal frequency. The amplification is restricted to a maximum amplification in a specific frequency range. The amplification exceeds the normal amplification or the maximum amplification for the duration of the identified sound and at most for a duration which lies below a setting time of a feedback whistling.
