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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hearing aid system comprising a database of acoustic transfer functions","description":"A hearing aid microphone system includes M microphones providing corresponding electric input signals.
