Abstract: The invention relates to a method and an apparatus for performing a microphone matching of a hearing aid comprising a first microphone, a second microphone and a receiver in a predetermined spatial arrangement to each other. The method comprises the steps of: generating an output sound signal by means of the receiver; picking up a first and second input sound signal by the first and second microphones while the output sound signal is generated; converting the first and second input sound signals into a first and second electrical microphone output signal by means of the microphones; determining a first and second microphone response of the microphones; determining a microphone response difference between the first microphone response and the second microphone response; determining a matching difference between the microphone response difference and a predetermined reference microphone response difference; and adapting at least a first microphone gain of the first microphone according to the matching difference to reduce the matching difference.

Abstract: An audio system includes a headset and a portable computing device. The headset includes a first speaker and a first microphone, a second speaker, a second microphone and a processing unit. The first microphone and the second microphone output a first signal and a second signal, respectively. The processing unit combines the first electrical signal and the second electrical signal into a third electrical signal, and communicates the third electrical signal to a portable computing device through an output channel. The portable computing device preferably includes an application that separates the third electrical signal into the first electrical signal and the second electrical signal. The application compensates the first electrical signal and the second electrical signal for a hearing loss of an individual.

Abstract: 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.

Abstract: A hearing aid includes an input providing an input signal representing sound in an environment, the input signal including no speech signal, or one or more speech signals from one or more speech sound sources and additional signal components, termed noise signal, from one or more other sound sources, an own voice detector, a voice activity detector, and a talker extraction unit to determine and/or receive one or more speech signals as separated one or more speech signals from speech sound sources other than the hearing aid user and to detect the speech signal originating from the voice of the user. The talker extraction unit provides separate signals, each including, or indicating presence of, one of the one or more speech signals. A noise reduction system determines speech overlap and/or gap between the speech signal originating from the user's voice and each of the separated one or more speech signals.
