摘要： It is described a method for controlling an adaptation of a behavior of an audio device (100) to a current acoustic environmental condition. The method comprises (a) monitoring an audio output signal (x(t), x'(t)) being provided to an acoustic output device (110) of the audio device (100) for outputting an acoustic output signal, (b) measuring an audio input signal (z(t)) being provided by an acoustic input device (120) of the audio device (100), wherein the audio input signal (z(t)) is indicative for a feedback portion of the acoustic output signal and for the current acoustic environmental condition, (c) determining a relation between the audio output signal (x'(t)) and the audio input signal (z(t)) and (d) adapting the behavior of the audio device (100) based on the determined relation. Further, it is described a data processor, a computer-readable medium and an audio device, which are adapted to control and/or to carry out the above mentioned method for controlling an adaptation of the behavior of an audio device (100) to a current acoustic environmental condition.
