Abstract
To provide a hearing aid system (1000) performing dichotic-listening binaural hearing aid processing which improves the clarity of speech and maintains the spatial perception ability. Each of first and second hearing aid devices (1100, 1200) includes a sound pickup unit (1110, 1210) and an output unit (1120, 1220) outputting a sound indicated by a suppressed acoustic signal. The hearing aid system (1000) includes: a first band suppression unit (1300) generating the suppressed acoustic signal indicating the sound outputted from the output unit (1120), by suppressing a signal in a first suppression-target band out of the acoustic signal outputted from the sound pickup unit (1110); and a second band suppression unit (1400) generating the suppressed acoustic signal indicating the sound outputted from the output unit (1220), by suppressing a signal in a second suppression-target band out of the acoustic signal outputted from the sound pickup unit (1210). The suppressed acoustic signals indicating the sounds outputted respectively from the output units (1120, 1220) include, in common, a signal in a non-voice band included in the acoustic signal.
