摘要： The sound processor and method uses a model of basilar membrane motion to select stimuli, based upon the predicted motion which the acoustic signal presented would produce in an acoustically excited normally hearing cochlea. The filter; used, in contrast to single channel per electrode approaches, cover multiple channels and overlap with each other. Consequently the stimuli presented produce a neural excitation pattern which approximates the spatio-temporal travelling wave observed on the basilar membrane in an acoustically excited normally hearing cochlea. Preferably, the predicted electrode stimuli are based upon the instantaneous predicted amplitude of the electrode location.

摘要： A sound processing method for auditory prostheses, such as cochlear implants, which is adapted to improve the perception of loudness by users, and to improve speech perception. The overall contribution of stimuli to simulated loudness is compared with an estimate of acoustic loudness for a normally hearing listener based on the input sound signal. A weighting is applied to the filter channels to emphasize those frequencies which are most important to speech perception for normal hearing listeners when selecting channels as a basis for stimulation.

摘要： The invention provides an amplifier for providing adaptive operation of an auditory prosthesis. The amplifier receives an input signal and produces an output signal, and comprises a gain control. Estimates of the current noise floor value of the input signal are obtained, and in response to a change in the current estimated noise floor value, the gain control alters the amount of gain applied to the input signal. Further, in response to the change in the current estimated noise floor value, the gain control alters a gain compression ratio of the amplifier across the dynamic range of the amplifier. The present invention allows for adaptive operation of the amplifier responsive to varying noise floor levels, while maintaining desired gain characteristics of the amplifier across a range of input signal levels.

摘要： A method for frequency transposition in a communication device Or a hearing device, respectively, is disclosed by transforming an acoustical signal into an electrical signal (s) and by transforming the electrical signal from time domain into frequency domain to obtain a spectrum (S). A frequency transposition is being applied to the spectrum (S) in order to obtain a transposed spectrum (S′), whereby the frequency transposition is being defined by a nonlinear frequency transposition function. Thereby, it is possible to transpose lower frequencies almost linearly, while higher frequencies are transposed more strongly. As a result thereof, harmonic relationships are not distorted in the lower frequency range, and at the same time, higher frequencies can be moved to a lower frequency range, namely to an audible frequency range of the hearing impaired person. The transposition scheme can be applied to the complete signal spectrum without the need for switching between non-transposition and transposition processing for different parts of the signal. Therefore, no artifacts due to switching are encountered. A higher transmission quality is obtained because more information is taken into account for the transmission.
摘要翻译：通过将声信号变换为电信号并将电信号从时域变换为频域来获得频谱（S），分别公开了通信装置中的频率转置方法或听力装置。为了获得转置频谱（S'），将频率变换应用于频谱（S），由此频率转置由非线性频率转置函数定义。因此，可以将较低频率几乎线性地转置，而更高频率被更强地转置。结果，谐波关系在较低的频率范围内不会失真，同时，较高的频率可以移动到较低的频率范围，即听觉受损者的听觉频率范围。转置方案可以应用于完整的信号频谱，而不需要在信号的不同部分的非转置和转置处理之间进行切换。因此，不会遇到由于切换引起的伪影。获得更高的传输质量，因为传输更多的信息被考虑在内。
