    摘要: A hearing aid includes an input unit, an output unit, a signal processing unit connected to said input unit and output unit, where the input unit, the signal processing unit and the output unit are forming part of a forward path of the hearing aid, where the signal processing unit is configured to apply a forward gain to the at least one electric input signal or a signal originating therefrom. The hearing aid further includes a feedback control unit configured to reduce a risk of howl due to acoustic, electrical, and/or mechanical feedback of an external feedback path from the output unit to the input unit of said hearing aid, where the hearing aid is configured to receive motion data characterising movement and/or acceleration and/or orientation and/or position of the hearing aid to control processing.

    摘要: Disclosed herein are embodiments of a method performed by a hearing aid and a hearing aid. An acoustical model can be used to generate first values (hk) for the multiple frequency channels based on first parameters (G, A, l); and a statistical model can be configured to generate second values (rk) for the multiple frequency channels based on values of second parameters (s1, s2, . . . , sn) and a set of basis vectors (u1, u2, . . . , un). An optimizer can be configured to obtain an optimized set of parameter values, wherein the optimized set of parameter values can be obtained by minimizing a difference between the first sound pressure levels (robs) and a combination of the first values (rk) and the second values (hk).

    摘要: A hearing aid microphone system includes M microphones providing corresponding electric input signals. Environmental sound at a given microphone includes a target sound signal propagated via an acoustic propagation channel from a direction to or a location of a target sound source to the microphone, and possible additive noise signals. The acoustic propagation channel is modeled. The hearing aid system includes: a processor connected to the microphones, and a database Θ having a multitude of dictionaries Δp, p=1, . . . , P, where p is a person index, of vectors, termed ATF-vectors, whose elements ATFm, m=1, . . . , M, are frequency dependent acoustic transfer functions representing direction- or location-dependent, and frequency dependent propagation of sound. The processor is configured to, at least in a learning mode of operation, determine personalized ATF-vectors based on the multitude of dictionaries Δp, the electric input signals, and the model of the acoustic propagation channels.

    摘要: A hearing aid includes a forward path for processing sound from the user's environment. The forward path includes a) a first microphone providing a first electric input signal representing sound as received at the first microphone, the first microphone being located away from an ear canal of the user, b) an audio signal processor for processing the first electric input signal, or a signal or signals originating therefrom, and for providing a processed signal, c) an output transducer for providing stimuli perceivable as sound to the user in dependence of the processed signal, and d) a second microphone configured to provide a second electric input signal representing sound received at the second microphone, the second microphone being located at or in the user's ear canal, and e) a feature extractor for extracting acoustic characteristics of the user's ear from the second electric input signal, or a signal originating therefrom.
