Abstract:
A listening device includes a) an input transducer; and b) an output transducer for converting a processed electric signal to an output sound; a forward signal path being defined there between and comprising c) a signal processing unit for processing an electric input signal or a signal derived therefrom and providing a processed output signal; d) a manually operable user interface located on the listening device allowing a user to control a function of the listening device; e) a feedback estimation system for estimating a feedback path from the output transducer to the input transducer, the feedback estimation system comprising e1) an adaptive filter having e11) a variable filter part and e12) an algorithm part comprising an adaptive algorithm.
