Abstract

A noise cancellation enabled audio system for tonal tinnitus treatment using ambient noise comprises an audio processor (PROC) and at least one filter having an adjustable filter function. An ear mountable playback device (HP) further comprises a speaker (SP) and at least one feedforward microphone (FF_MIC). The audio processor (PROC) is configured to receive an input signal (Z(s)) from the feedforward microphone (FF_MIC) indicative of ambient noise and determine a filter transfer function (HF(s)) to realize a predetermined target transfer function (HT(s)), wherein the target transfer function (HT(s)) is configured to attenuate and/or amplify the input signal (Z(s)) in a predetermined frequency range. The filter function is adjusted depending on the filter transfer function (HF(s). The filter is configured to provide a system output signal (Y(s)) by filtering the input signal (Z(s)) depending on the filter function.
