Abstract (en)
[origin: EP1571880A2] The hearing aid system uses a silicon microphone [SM] for low frequencies and an Electret microphone [EM] for the high frequency range. The outputs are fed respectively into low pass [TP] and high pass [HP] filters and the outputs summed [A] before being fed to a signal processor.
