Abstract:
In a hearing device with multiple microphones, and a signal generation method, the dynamic range of hearing devices is improved by using a combination including a silicon microphone and an electret microphone for the hearing device input. Low frequencies thus can be acquired by the silicon microphone and high frequencies can be acquired by the electret microphone, in order to generate a wide-band hearing device input signal. The fact that a silicon microphone possesses a lower internal noise than a conventional electret microphone at low frequencies is utilized.
