Abstract: A hearing aid comprises a) an ITE-part adapted for being located at or in an ear canal of the user, b) a forward path for processing sound from the environment of the user. The forward path comprises b1) at least one first input transducer providing at least one first electric input signal representing said sound as received at the respective at least one first microphone, said at least one first input transducer being located to allow picking up sound from the environment of the user, b2) an audio signal processor comprising a gain unit for applying a frequency and/or level dependent prescribed gain to compensate for a hearing impairment of the user to said at least one first electric input signal, or a signal or signals originating therefrom, and configured to provide a processed signal in dependence thereof, b3) an output transducer for providing stimuli perceivable as sound to the user in dependence of said processed signal. The hearing aid further comprises c) at least one second input transducer providing at least one second electric input signal representing said sound as received at the at least one second input transducer, the at least one second input transducer being located in said ITE-part to pick up sound at the eardrum of the user, d) a correlator configured to determine a correlation measure between the at least one second electric input signal, or a signal originating therefrom, and a signal of the forward path and e) a gain modifier configured to modify said gain of the gain unit in dependence of said correlation measure. A method of operating a hearing aid is further disclosed.

Abstract: A method of defining and setting a nonlinear signal processing of a hearing device, e.g. a hearing aid, by machine learning is provided. The hearing device being configured to be worn by a user at or in an ear or to be fully or partially implanted in the head at an ear of the user, the method comprising providing at least one electric input signal representing at least one input sound signal from an environment of a hearing device user, determining a normal-hearing representation of said at least one electric input signal based on a normal-hearing auditory model, determining a hearing-impaired representation of said at least one electric input signal based on a hearing-impaired auditory model, determining optimised training parameters by machine learning, where determining optimised training parameters comprises iteratively adjusting the training parameters, and comparing the normal-hearing representation with the hearing-impaired representation to determine a degree of matching between the normal-hearing representation and the hearing-impaired representation, until the degree of matching fulfils predetermined requirements, and, when the degree of matching fulfils the predetermined requirements, determining corresponding signal processing parameters of the hearing device based on the optimised training parameters. A hearing device is further provided.

Abstract: A binaural hearing system comprises A) left and right hearing devices, each comprising a1) an input unit providing an electric input signal representing sound; and a2) an output unit, B) a binaural level and/or gain estimator comprising b1) left and right level estimators, each comprising respective fast and slow level estimators configured to provide respective fast and slow level estimates of respective electric input signals, b2) a fast binaural level comparison unit receiving the fast level estimates of the respective left and right fast level estimators and providing a fast binaural level comparison estimate; and b3) a fast binaural level and/or gain enhancer providing respective left and right binaural level and/or gain modification estimates, in dependence of said fast binaural level comparison estimate at said left and right ears, respectively, of the user. The binaural hearing system provides that the interaural level cues are either compressed, maintained or enhanced independent of each other.

Abstract: The invention relates to a binaural hearing aid device, comprising a first hearing aid and a second hearing aid, respectively. Each hearing aid comprises a microphone unit, a receiver unit, an audio processor and a speaker unit. The microphone unit is configured to receive an acoustic front tone, indicative of a front part of a surround sound, and to convert the acoustic front tone into an electric front signal. The receiver unit is configured to receive a wireless rear communication signal, indicative of a rear part of the surround sound, and to convert the rear communication signal into an electric rear signal. The audio processor is configured to receive the electric front signal and the electric rear signal and to determine a processed electric rear signal with respect to the electric front signal, by adjusting a time delay between the electric rear signal and the electric front signal and by adjusting a sound level of the electric rear signal according to a sound level of the electric front signal, wherein the audio processor of the first hearing aid is configured to adjust the time delay and the sound level of the electric rear signal differently than the audio processor of the second hearing aid, such that the combined acoustic output of the first hearing aid and of the second hearing aid form the rear part of the surround sound.
