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.

Method and device for generating a database of noise

What is described is a method for associating noises of at least one signal class (like disturbing noise) of a plurality of signal classes (like disturbing noise and non-disturbing noise). The method has the steps of 'receiving environmental noises' and 'establishing whether the environmental noises or a set of parameters derived from the environmental noises fulfill/s a predefined rule which describes the signal class of the plurality of signal classes'. Starting from this, the steps of &#x201c;logging that the predefined rule has been fulfilled&#x201d;, &#x201c;recording the environmental noises received for a migrating time window&#x201d;, &#x201c;deriving a set of parameters from the environmental noises for the migrating time window and storing the set of parameters&#x201d; or &#x201c;emitting an activation signal for another device for associating a noise&#x201d; are performed.
