Disclosed is a hearing aid system capable of increasing the clearness of sound spoken by a speaker while reproducing the incoming direction of the sound spoken by the speaker without using an inverse mapping rule. The hearing aid system includes a sound source input section which receives sounds coming from sound sources as input to convert the input sounds to first acoustic signals, a sound source separating section which separates the first acoustic signals converted by the sound source input section into sound source signals corresponding to the sound sources, a binaural microphone which is disposed on left and right ears, and receives the sounds coming from the sound sources as input to convert the input sounds to second acoustic signals, a directional sense component calculating section which calculates directional sense components representing the directional sense of the sound sources with the binaural microphone as a base point from the left and right second acoustic signals converted by the binaural microphone, an output signal generating section which generates left and right output acoustic signals on the basis of the sound source signals and the directional sense components, and a binaural speaker which outputs the left and right output acoustic signals generated by the output signal generating section. |
