METHOD OF CONTROLLING AN EFFECT STRENGTH OF A BINAURAL DIRECTIONAL MICROPHONE, AND HEARING AID SYSTEM

摘要

A hearing aid system has at least two hearing aid devices to be worn on both sides of a wearer's head. The hearing aid devices have a transducer for picking up an acoustic signal and converting same into a first audio signal in each case. A signal processing unit processes audio signals received from each hearing aid device through a signal connection. The signal processing unit evaluates a signal component from a preferred direction in relation to the head of the wearer in the first audio signals. By way of the first audio signals the signal processing unit generates a first binaural directional microphone signal and adjusts its directional characteristic as a function of the evaluation.

1. A method of operating a hearing aid system having at least two hearing aid devices to be respectively worn on two sides of the head of a wearer, each of the hearing aid devices having a transducer for picking up an acoustic signal and converting the acoustic signal into a first audio signal, and the hearing aid system having a signal processing unit for processing audio signals and a signal connection for transmitting a first audio signal from each hearing aid device to the signal processing unit, the method comprising:
evaluating with the signal processing unit a signal component from a preferred direction in relation to the head of the wearer in the first audio signals; and based on the first audio signals, generating with the signal processing unit a first binaural directional microphone signal and adjusting a directional characteristic of the signal as a function of the evaluating step.
