摘要：
The present invention relates to a new method for the detection of whistling in an audio system in general and a hearing aid in particular, the method comprising the steps of 1) determining an average frequency of an input signal of the audio system, and 2) determining whether feedback related whistling is present in the input signal of the audio system by evaluating the stability of the average frequency.
