Abstract
A method is described for reduction of occlusion effects in an acoustic appliance which closes an auditory channel, wherein an audio signal in the transmission path of the acoustic appliance is processed by a signal processing unit and is emitted via an output transducer, which is arranged in the auditory channel, as an acoustic signal. A resultant sound signal is then detected by an auditory channel microphone and is supplied to a variable loop filter which is arranged in a feedback loop of an occlusion reduction unit for the acoustic appliance. The output signal from the loop filter is injected into the transmission path of the audio signal. The occlusion reduction unit is in this case controlled adaptively, with at least one signal from the transmission path of the audio signal and/or from the feedback loop being used to control the loop filter for the occlusion reduction unit.
