Patent ID: 8670583

Claim:
A hearing aid system comprising: a sound source input section configured to receive sounds from sound sources as an input thereof and to convert the input sounds to first acoustic signals; a sound source separating section configured to separate the first acoustic signals converted by the sound source input section into sound source signals corresponding to respective sound sources; a binaural microphone disposed at left and right ears and, and being configured to receive the sounds from the sound sources as an input thereof and to convert the input sounds to left and right second acoustic signals; a directional sense component calculating section configured to calculate a directional sense component representing a directional sense of the sound sources with respect to the binaural microphone as a base point, based on the left and right second acoustic signals converted by the binaural microphone; an output signal generating section configured to generate left and right output acoustic signals by synthesizing the sound source signals and the directional sense component; and a binaural speaker configured to output the left and right output acoustic signals generated by the output signal generating section.
