Abstract

A method and an apparatus for determining parameters of a room, such as a contribution thereof when sound is generated therein. These parameters and this contribution may be used for adapting sound fed to the room to counteract these. The parameters are generated on the basis of a trend of quantified sound pressure in the room after a sound has been generated.
