Abstract: A method operates a hearing aid system in which a dynamic range scheme for an automatic gain control is modified depending on the situation. A gain factor is set by the automatic gain control which has a dynamic range processor operated with a dynamic range scheme defining the gain factor in dependence on a level of an input signal. A corresponding hearing aid system carries out this method.

Abstract: A method for rejecting inherent noise of a microphone arrangement that includes a first microphone and a second microphone. The first microphone generates a first microphone signal from an ambient sound signal and the second microphone generates a second microphone signal from the ambient sound signal. A measure of correlation between the first microphone signal and the second microphone signal is ascertained, and inherent noise of the first microphone and/or of the second microphone in the first or second microphone signal is rejected on the basis of the measure of correlation.

Abstract: A hearing system contains a hearing instrument and the hearing instrument is configured to support the hearing of a hearing-impaired user. The hearing instrument is operated via an operating method. The method includes capturing a sound signal from an environment of the hearing instrument, processing the captured sound signal to at least partially compensate the hearing-impairment of the user and outputting the processed sound signal to the user. The captured sound signal is analyzed to recognize speech intervals, in which the captured sound signal contains speech. During recognized speech intervals, at least one time derivative of an amplitude and/or a pitch of the captured sound signal is determined. The amplitude of the processed sound signal is temporarily increased, if the at least one derivative fulfills a predefined criterion.

Abstract: A method operates a hearing device where a first directional signal and a second directional signal are generated in the hearing device from a sound signal of the environment. A parameter is determined based on the first directional signal and the second directional signal, which represents a quantitative measure of the stationarity of a sound signal. A noise-optimized signal is generated from the first directional signal and the second directional signal based on the parameter. The method is performed by a hearing device having a first microphone and a second microphone for generating a first directional signal and a second directional signal. The hearing device is configured to implement the corresponding method.
