Abstract
Adaption of signal processing for actively reducing occlusion in hearing apparatuses, and in particular in hearing aids, is to be automated further. For this purpose, a transducer transmission function, which is defined for the transmission path from the input of a receiver via the auditory canal to the output of a microphone, be subjected to an automatic plausibility check. An adjustable filter via which the microphone signal is fed back is only altered if the transducer transmission function is plausible according to a predefined criterion.
