    摘要： A method is described for reduction of occlusion effects in an acoustic appliance 1 which closes an auditory channel, wherein an audio signal S in the transmission path of the acoustic appliance 1 is processed by a signal processing unit DSP and is emitted via an output transducer R, which is arranged in the auditory channel, as an acoustic signal. A resultant sound signal Y is then detected by an auditory channel microphone M and is supplied to a variable loop filter B which is arranged in a feedback loop of an occlusion reduction unit 10 for the acoustic appliance 1. The output signal T from the loop filter B is injected into the transmission path of the audio signal S. The occlusion reduction unit 10 is in this case controlled adaptively, with at least one signal X, W, Z from the transmission path of the audio signal S and/or from the feedback loop being used to control the loop filter B for the occlusion reduction unit 10.
