Hearing aid device and method for operating a hearing aid device

摘要

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.

1. A hearing aid device, comprising:
an input converter for receiving an input signal and converting the input signal into an electrical input signal; a signal processing unit for processing and frequency-dependent amplification of the electrical input signal and for generating an electrical output signal; an output converter for converting the electrical output signal into an output signal which can be perceived by a user as an acoustic output signal; a sound detector facility for identifying sounds in a speech signal going into the hearing aid device; means for briefly increasing an amplification above a normal amplification for at least one frequency range, in which an identified sound contains signal components; means for setting the normal amplification of the electrical input signal in dependence on a signal frequency, whereby:
the amplification is restricted to a permanently possible, maximum amplification at least in a specific frequency range;the amplification being set such that the amplification exceeds the normal amplification or the permanently possible, maximum amplification at least essentially for a duration of the identified sound; andthe amplification can be set such that the amplification exceeds the normal amplification or the permanently possible, maximum amplification at most for a duration which lies below a setting time of a feedback whistling.
