Title: HEARING DEVICE WITH ACOUSTIC SHOCK CONTROL AND METHOD FOR ACOUSTIC SHOCK CONTROL IN A HEARING DEVICE
Abstract:
The present invention pertains to a hearing device for being worn at or at least partly within an ear of a user and comprising an acoustic shock detector (4) for detecting an acoustic shock event present in an input audio signal from an input transducer (1) and providing shock detection information related to the acoustic shock event. The hearing device further comprises an acoustic shock controller (5) for determining a first gain factor (Gb) and a second gain factor (Gp) in dependence of the shock detection information, a first attenuator (6) for attenuating a processed input audio signal by the first gain factor (Gb) and providing an attenuated audio signal to an output limiter (2) providing a limited audio signal, and a second attenuator (7) for attenuating the limited audio signal by the second gain factor (Gp) and providing a further attenuated audio signal to an output transducer (3). The present invention further relates to a corresponding method for acoustic shock control in a hearing device.
