Abstract (en)
[origin: US2018255407A1] A method for the frequency distortion of an audio signal includes splitting the audio signal into a plurality of specified frequency bands, in which a band limit frequency is defined in each case by two respective immediately adjacent frequency bands. A first frequency band and a second frequency band lying immediately above the first frequency band are determined on the basis of the audio signal. A distortion of the frequencies differing from the distortion applied to signal components in the second frequency band is applied to signal components in the first frequency band, and a frequency-distorted signal is generated as a result. A method for suppressing an acoustic feedback in an acoustic system and a hearing aid are also provided.
