A bone anchored hearing device includes an electromagnetic vibrator for generating a vibration in order to transmit sound through a bone of a user to an ear of the user; and a compensator for at least in part compensating a distortion in the vibration of the electromagnetic vibrator. Further, a signal processing method for a bone anchored hearing device includes providing, by an input transducer, an electric input signal representing sound of a surrounding of a user of the bone anchored hearing device; processing, by a signal processing unit, the electric input signal and providing a processed electric signal; generating, by an electromagnetic vibrator, based on the processed electric signal, a vibration in order to transmit sound through a bone of the user to an ear of the user; and at least in part compensating, by a compensator, a distortion in the vibration of the electromagnetic vibrator.

Distortion compensation for bone anchored hearing device

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.
