<p>A hearing aid is provided with a microphone (101), an external input terminal (102), a hearing aid processing unit (150) to which sound signals from the microphone (101) and external input terminal (102) are input, and a receiver (113) to which sound signals processed by this hearing aid processing unit (150) are output. The hearing aid processing unit (150) comprises a mixing unit (112) which mixes the sound signals from the microphone (101) with the sound signals from the external input terminal (102) and outputs sound signals to the receiver (113), a mixing ratio determining unit (111) which determines the mixing ratio, at this mixing unit (112), for the sound signals from the microphone (101) and the sound signals from the external input terminal (102), and a face movement detection unit (110) which is connected to this mixing ratio determining unit (111).</p> |
