HEARING AID WITH SPATIAL SIGNAL ENHANCEMENT

摘要

A new binaural hearing aid system is provided with a hearing aid in which signals that are received from external devices, such as a spouse microphone, a media player, a hearing loop system, a teleconference system, a radio, a TV, a telephone, a device with an alarm, etc., are filtered with binaural filters in such a way that a user perceives the signals to be emitted by respective sound sources positioned in different spatial positions in the sound environment of the user, whereby improved spatial separation of the different sound sources is facilitated.

主权项

1. A binaural hearing aid system comprising:
a first input for provision of a first audio input signal representing sound output by a first sound source and received at the first input; a second input for provision of a second audio input signal representing sound output by a second sound source and received at the second input; a first binaural filter for filtering the first audio input signal and configured to output a first right ear signal for a right ear of a user of the binaural hearing aid system and a first left ear signal for a left ear of the user, wherein the first right ear signal and the first left ear signal are (1) phase shifted with a first phase shift with relation to each other, (2) equal to the first audio input signal multiplied with a first right gain and a first left gain, respectively, the first left gain being different from the first right gain, or (3) equal to the first audio input signal multiplied with the first right gain and the first left gain, respectively, and phase shifted with the first phase shift with relation to each other; a first ear receiver; and a second ear receiver; wherein one of the first ear receiver and the second ear receiver is configured to provide an acoustic signal for transmission towards an eardrum of the first ear of a user of the binaural hearing aid system based on the first right ear signal, and the other one of the first ear receiver and the second receiver is configured to provide an acoustic signal for transmission towards an eardrum of the second ear of the user of the binaural hearing aid system based on the first left ear signal.
