Abstract
An adaptive level estimator for providing a level estimate of an electric input signal representing sound is provided. The adaptive level estimator comprises a first level estimator that provides a first level estimate of the electric input signal in a first number Kof frequency bands; a second level estimator that provides attack/release time constants associated with a second level estimate of the electric input signal in a second number Kof frequency bands, wherein Kis smaller than K; and a level control unit that provides a resulting level estimate based on said first level estimates and said attack/release time constants associated with said second level estimates. The level estimator may be used in devices or applications that benefit from a dynamic adaptation of an input signal level to a listener's dynamic range of sound level perception, or to any other specific dynamic range deviating from that of the environment sound.
