HEARING INCLUDING A SEPARATE MICROPHONE DEVICE TO CALL A USER'S VOICE

摘要

The application relates to a hearing system comprising a hearing device and a separate microphone unit adapted for picking up a voice of a user. The microphone unit comprises a) a multitude M of input units for picking up or receiving a signal representative of a sound from the environment, M bering ‰¥ 2; b) an adaptive multi-input unit noise reduction system for providing an estimate S of a target signal s comprising the user's voice, the multi-input unit noise reduction system comprises a multi-input beamformer filtering unit configured to determine filter weights w(k,m) for providing a beamformed signal, wherein signal components from other directions than a direction of a target signal source are attenuated, whereas signal components from the direction of the target signal source are left un-attenuated; and c) antenna and transceiver circuitry for transmitting said estimate S of the user's voice to another device. The hearing system facilitates communication between a wearer of a hearing device and another person via a telephone. The invention may e.g. be used in hearing aids in connection with handsfree telephone systems, mobile telephones, teleconferencing systems, etc.
