Adjusting hearing aid with microphone system with variable directional characteristic involves adjusting directional characteristic depending on acoustic input signal frequency and hearing threshold

摘要

The method involves determining the quiet listening threshold of a hearing aid wearer depending on the signal frequency of a test signal that is fed into the wearer's ear and adjusting the directional characteristic of the microphone system (1-3) depending on the frequency of the acoustic input signal and the determined threshold. Independent claims are also included for the following: (a) a hearing aid with a microphone system with a variable directional characteristic (b) and a programming device for programming a hearing aid.
