Abstract: 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 (Sin) of an acoustic input signal, b) calculating at least one statistical parameter (P) of the digital representation (Sin) of the acoustic input signal, c) calculating a compression ratio function (CRf) based—on a prescribed constant compression ratio (CRpr), said prescribed constant compression ratio (CRpr) uniformly mapping acoustic input signals of a selected magnitude to acoustic output signals of a selected magnitude, and—on at least one statistical parameter (P) calculated in step b), and d) applying the non-uniform compression ratio function (CRf) according to step c) on the digital representation (Sin) of the acoustic input signal delivering a digital representation (Sout) of an enhanced acoustic output signal.

Abstract: The invention relates to a method for enhancing the configuration of a hearing aid device (2) of a user, said method using an external configuration unit (3) accessing a database of previously known user records, wherein the hearing aid device (2) is arranged to be configured according to an individual set of configuration parameters.
