A method for generating a database, having “receiving environmental noises” (e.g. disturbing noise) and “buffered environmental noises for a migrating time window” (like 30 or 60 seconds) alternatively “deriving a set of parameters relative to the environmental noises” and of “buffering the set of parameters for the migrating time window”, he buffered environmental noises or the buffered set of parameters being generally referred to as recording, furthermore “obtaining a signal”, which identifies a signal class (like disturbing noise) of a plurality of signal classes (disturbing noise and non-disturbing noise) in the environmental noises, and “storing the buffered recordings responsive to the signal” in a memory (e.g. internal or external memory). Obtaining and storing are repeated in order to set up the database which has a plurality of buffered recordings for the same signal class.
