ABSTRACT:
To improve the speech comprehensibility given treatment with a hearing aid device, during the operation of the hearing aid device speech signal levels and noise signal levels are determined in a plurality of frequency bands of an input signal. An automatic adjustment of the amplification follows, dependent on the determined signal level and the signal frequency. The determination of amplification parameters thereby ensues under inclusion of a loudness model and a speech comprehensibility model.
