Abstract

In a method for tuning at least one parameter of a noise cancellation enabled audio system with an ear mountable playback device (HP) comprising a speaker (SP) and a feedforward microphone (FF_MIC) the playback device (HP) is placed onto a measurement fixture (MF), the speaker (SP) facing a test microphone (ECM) located within an ear canal representation (EC). The parameter is varied between a plurality of settings while a test sound is played. A measurement signal from the test microphone (ECM) is received and stored in the audio system at least while the parameter is varied. A power minimum in the stored measurement signal and a tune parameter associated with the power minimum are determined in the audio system from the plurality of settings of the varied parameter.
