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： The application relates to a hearing device, e.g. a hearing aid, adapted for being worn by a user and for receiving sound from the environment of the user to process the sound with a view to the user's intelligibility of speech in said sound, wherein an estimate of the user's intelligibility of speech in said sound being defined by a speech intelligibility measure I of said sound at a current point in time t, the hearing device comprising a) an input unit for providing a number of electric input signals y, each representing said sound in the environment of the user, b) a signal processor for processing said number of electric input signals y according to a configurable parameter setting Θ of one or more processing algorithms, which when applied to said number of electric input signals y provides a processed signal yp(Θ) in dependence thereof, the signal processor being configured to provide a resulting signal yres, c) a controller configured to control the processor to provide said resulting signal yres at a current point in time t in dependence of c1) a parameter set Φ defining a hearing profile of the user, c2) said electric input signal(s) y or characteristics extracted from said electric input signal(s), e.g. a noise covariance matrix Cv and/or covariance matrix CY of noisy signals, c3) a current value I(y) of said speech intelligibility measure I for at least one of said electric input signals y, c4) a desired value Ides of said speech intelligibility measure, c5) a first parameter setting Θ1 of said one or more processing algorithms, c6) a current value I(yp(Θ1)) of said speech intelligibility measure I for a first processed signal yp(Θ1) based on said first parameter setting Θ1, and c7) a second parameter setting Θ′ of said one or more processing algorithms, which, when applied to said number of electric input signals y, provides a second processed signal yp(Θ′) exhibiting said desired value Ides of said speech intelligibility measure. The application further relates to a method of operating a hearing device. The invention may e.g. be used in hearing aid systems, or other portable audio processing systems.

摘要： A hearing aid comprises a forward path comprising a) an input transducer for converting sound (x(n), v(n)) in an environment around the hearing aid to an electric input signal (y(n)) representing said sound; b) a hearing aid processor for processing said electric input signal (y(n)), or a signal originating therefrom (e(n)), and to provide a processed signal (u(n)) based thereon; c) an output transducer for converting said processed signal (u(n)), or a signal originating therefrom (ua(n)), to acoustic stimuli presented to said eardrum of the user. The hearing aid further comprises d) a feedback control system for attenuating or cancelling feedback propagated via a feedback path (H) from an electric input signal to said output transducer to an electric output from said input transducer.

摘要： A hearing aid comprises a) a multitude of M input transducers each providing an electric input signal representative of environment sound in a time-frequency representation (k, l), and each comprise varying amounts of target (s) and noise (v) signal components; b) a signal processor configured to process said multitude of electric input signals; and comprising a beamformer filter configured to receive said multitude M of electric input signals and to provide a spatially filtered signal and a post-filter configured to receive said spatially filtered signal and to provide an estimate Ŝ(k, l) of a target signal representing said target signal components from said target sound source. The signal processor is configured to provide estimates of power spectral densities λs(k, l) of said target signal components in dependence of inter-frequency bin relationships between the spectral components enforced by properties of the electric input signals across at least some of said frequency bins.
