Abstract (en)
[origin: EP2104376A2] The method involves receiving sound in an auditory canal (11) by a microphone (17) by outputting microphone signals. The signals are filtered by a loop filter (18). The filtered signals are feedback to an input of a receiver. Part of transducer transmission function defined for a transmission path (19) from the input of the receiver via the canal to the output of the microphone, is measured. The filter is adjusted based on the function, which is subjected to an automatic plausibility check. The filter is only altered if the function is plausible according to a predefined criterion. An independent claim is also included for a hearing aid for active occlusion reduction.
