ABSTRACT:
An arrangement for reproducing audio signals includes a pitch control device for increasing or decreasing the amplification of audio signals in one or more defined frequency ranges and a volume control device for increasing and decreasing the amplification of the audio signals in a full effective frequency range of the audio signals wherein the pitch control device reduces the amplification in the defined frequency ranges if the amplification of the audio signals in the full effective frequency range is increased by the volume control device and wherein the pitch control device increases the amplification of the audio signals in the defined frequency ranges if the volume control device decreases the amplification of the audio signals in the full effective frequency range. In order to compensate for noise interference signals which occur and in order to suppress them in the audio signal sound pattern which can be heard by a human being, an additional amplification component is added to the frequency curve in at least one of the defined frequency ranges in which noise interference occurs.
