The invention relates to a method for processing an acoustic input signal, preferably a speech signal, said method comprising the following steps: a) receiving a digital representation (S) of an acoustic input signal, b) calculating at least one statistical parameter (P) of the digital representation (S) of the acoustic input signal, c) calculating a compression ratio function (CR) based&#x2014;on a prescribed constant compression ratio (CR), said prescribed constant compression ratio (CR) uniformly mapping acoustic input signals of a selected magnitude to acoustic output signals of a selected magnitude, and&#x2014;on at least one statistical parameter (P) calculated in step b), and d) applying the non-uniform compression ratio function (CR) according to step c) on the digital representation (S) of the acoustic input signal delivering a digital representation (S) of an enhanced acoustic output signal.
