Method of operating a hearing aid and hearing aid

Abstract

The procedure for operating a hearing aid involves the following steps: Processing of an incoming hearing signal with the aid of signal processing and outputting of a processed hearing signal which is at least in parts shifted by a frequency shift with respect to the incoming hearing signal and which is amplified by an initial amplification factor, Determining an amplitude ratio of the direct hearing signal and the processed hearing signal at a place of superposition where the two hearing signals superpose in a user's ear, Adjusting the initial amplification factor for the processed hearing signal depending on the amplitude ratio. This reduces or avoids unwanted artifacts caused by a superposition of the processed hearing signal and the direct hearing signal at the place of superposition (eardrum).
