    摘要: The invention relates to a method for setting a frequency-dependent amplification of a hearing aid (30), wherein the amplification is automatically adjusted according to the frequency. The method comprises the following steps: selecting a sound having specific frequency (f1...fn); outputting the sound by means of a transmission element (42), in particular a speaker; detecting an analysis noise, which comprises an ambient noise (32), if present, and a reflection (48) of an output noise (46), which is output by means of the transmission element (42), by means of a sensor element (34), in particular a microphone; extracting a rejection of the fed-in sound from the detected analysis noise; determining a reflection component (S1...Sn) for the specific frequency (f1...fn) of the fed-in sound; and adapting the amplification in a frequency-specific manner on the basis of the reflection component determined in such a way.
