    Abstract: A hearing aid comprises at least one input unit for providing at least one stream of samples of an electric input signal in a first domain; at least one encoder configured to convert said at least one stream of samples of the electric input signal in the first domain to at least one stream of samples of the electric input signal in a second domain; a processing unit configured to process said at least one electric input signal in the second domain, to provide a compensation for the user's hearing impairment, and to provide a processed signal as a stream of samples in the second domain; a decoder configured to convert said stream of samples of the processed signal in the second domain to a stream of samples of the processed signal in the first domain. The at least one encoder is configured to convert a first number of samples from said at least one stream of samples of the electric input signal in the first domain to a second number of samples in said at least one stream of samples of the electric input signal in the second domain. The decoder is configured to convert said second number of samples from said stream of samples of the processed signal in the second domain to said first number of samples in said stream of samples of the electric input signal in the first domain. The second number of samples is larger than the first number of samples. The at least one encoder is trained, and at least a part of said processing unit providing said compensation for the user's hearing impairment is implemented as a trained neural network. A method of operating a hearing aid is further disclosed. Thereby an improved hearing aid may be provided.

The hearing aid comprises a microphone system comprising a multitude of M of microphones arranged in said hearing aid and adapted to provide M corresponding electric input signals xm(n), m=1, . . . , M, n representing time. The environment sound at a given microphone comprises a mixture of a) a target sound signal sm(n) propagated via an acoustic propagation channel from a direction to or a location (θ) of a target sound source to the mth microphone of the hearing aid when worn by the user, and b) possible additive noise signals vm(n) as present at the location of the mth microphone, wherein the acoustic propagation channel is modeled as xm(n)=sm(n)hm(θ)+vm(n), and wherein hm(θ) is an acoustic impulse response for sound for that acoustic propagation channel. The hearing aid system comprises A) a processor connected to said number of microphones, and B) a database Θ comprising 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 (θ), and frequency dependent (k) propagation of sound from a direction or location (θ) of a target sound source to each of said M microphones, k being a frequency index, k=1, . . . , K, where K is a number of frequency bands, when said microphone system is mounted on a head at or in an ear of a natural or artificial person (p′), and wherein each of said dictionaries Δp comprises ATF-vectors for a given person (p) for a multitude of different directions or locations θj, j=1, . . . , J, relative to the microphone system. The processor is configured to, at least in a learning mode of operation, determine personalized ATF-vectors (ATF*) for said user based on said multitude of dictionaries Δp of said database Θ, said electric input signals xm(n), m=1, . . . , M, and said model of the acoustic propagation channels.

The selector/mixer is controlled by a source selection control signal provided by a source selection processor. The source selection processor is configured to determine said source selection control signal in dependence of a comparison of said beamformed signal and said external electric sound signals or processed versions thereof. A hearing device, and a method of operating a hearing system is further disclosed. The invention may e.g. be used in hearing aids, headsets, active ear protection devices, headphones, etc.
