(57) A method for detecting and automatically selecting an input signal in a hearing aid in which at least two analog input signals are available, comprises the steps of
  • analysing the analog input signals and detecting, for each analog input signal, whether it comprises a relevant signal,
  • selecting, according to results of said analysis, at least one selected input signal that comprises a relevant signal for further processing, and
  • controlling a signal routing means (4) to selectively route each one of the at least one selected input signals to further processing means (6).

A hearing aid according to the invention comprises means to perform the above method.
