Acoustic system with automatic switchover
First Claim
1. A hearing aid system, comprising first and second hearing aids, the first and second hearing aids each comprising:
- a microphone device;
an output device;
a signal processing device for picking up a first input signal generated by the microphone device and for outputting an output signal to the output device; and
a receiver device for receiving electromagnetic signals and for outputting a second input signal to the signal processing device, whereinthe signal processing device;
comprises a high-frequency detector for analyzing the second input signal output to the signal processing device, andis configured to generate an output signal for controlling the signal processing device based on the analyzed second input signal, wherein the signal processing device of either the first or second acoustic system comprises a signal measurement device for determining a level of or a level difference between the output signals generated by the high-frequency detectors of the first and second acoustic systems, the level or level difference used for adjusting signal processing.

Abstract
The automatic switching of acoustic systems and especially of hearing aids into different processing programs is to be improved. To this end there is provision for the signal processing device of the acoustic system to feature a high-frequency detector for analysis of an input signal, with the output signal of said device being able to be used for processing one or more input signals by the signal processing unit. Specifically the presence of an active mobile telephone which emits electromagnetic radiation in the high-frequency range can be established in this way. This enables the system to be switched into telephone made with a high degree of certainty to suit a particular situation.
