Abstract

A hearing aid is provided that avoids disturbing acoustic effects caused by on, off, or switchover events. The signal processing in the hearing aid is switched in sliding fashion from a first operating condition into a second operating condition. According to the invention, both operating conditions are simultaneously present in the hearing aid during the switching event. The sliding transition ensues by a parallel signal processing in at least two signal paths of the hearing aid, whereby a signal that results from the first operating condition and a signal that results from the second operating condition are added in changing weighting.
