Hearing system with at least one hearing instrument worn at the head of the user and procedures for operating such hearing system

摘要

A hearing system (2) shall be specified to support the hearing ability of a user comprising at least one hearing instrument worn on the head of the user (4). A procedure for operating the hearing system (2) is also indicated. At least two input converters (6) of the audio system (4) record a sound signal from a user environment and convert it into input audio signal (I1, I2). The input audio signals (I1, I2) are processed in a signal processing step to produce an output audio signal (O),which is issued by means of an output converter (8) of the hearing aid (4). In the signal preparation step, the input audio signals (I1, I2) or audio signals derived from them by pre-processing (I1',I2') dampened by means of an adaptive amplifier (28) according to a variable directional characteristic with a directional force (s) in order to produce a directional audio signal (R1). The directional characteristic is varied with a specified adaptation speed (v1) such that the energy content of the directed audio signal (R1) is minimized. Adaptation speed (v1) and/or directional strength (s) shall be based on an analysis of the input audio signals (I1, I2) or the pre-processed audio signals (I1',I2') variable.
