Abstract
A hearing aid device has an input converter for receiving an input signal and converting the signal into an electrical input signal, a signal processing unit for processing and frequency-dependent amplification of the electrical input signal and generating an electrical output signal, an output converter for converting the electrical output signal into an acoustic output signal, and a sound detector facility for identifying sounds in a signal. Facilities increase an amplification above a normal amplification for a frequency range in which an identified sound contains signal components. Further facilities set the normal amplification of an electrical input signal in dependence on a signal frequency. The amplification is restricted to a maximum amplification in a specific frequency range. The amplification exceeds the normal amplification or the maximum amplification for the duration of the identified sound and at most for a duration which lies below a setting time of a feedback whistling.
