Patent Images
1. A hearing aid device, comprising:
- an acoustic pick-up for picking up an acoustic signal;
an induction pick-up for picking up an induction signal;
a control device for controlling the hearing aid device;
a comparison device configured for comparing a picked-up acoustic signal to a picked-up induction signal and supplying a comparison result to the control device for controlling the hearing aid device on the basis of the comparison result.

Abstract
A beneficial automatic switching and control of hearing aid devices is based on a respective auditory situation. An acoustic signal and an induction signal are picked up for controlling the hearing aid device. Subsequently, the acoustic signal is evaluated and compared to the induction signal in view of prescribed parameters such as level, carrier frequency, modulation frequency, degree of modulation and/or estimated signal-to-noise ratio. Finally, the hearing aid device is controlled on the basis of the comparison in view of the input signal, individual hearing aid parameters or entire hearing programs.
