1. A hearing aid system, comprising:
- a first and a second hearing aid, each comprising;
an input transducer for receiving an input signal and converting into an electrical input signal,a signal processing unit for processing and amplifying the electrical input signal and emitting an electrical output signal,an output transducer for converting the electrical output signal into an output signal perceivable by a user as an acoustic signal, anda wireless signal transmission between the hearing aids,wherein a signal transmitted wirelessly from the second hearing aid to the first hearing aid is received in the first hearing aid,wherein the first hearing aid automatically switches the respective hearing aid on or off based on a field strength of the received signal,wherein for the automatic switching the respective hearing aid on or off, the field strength or a variable dependent on the field strength is at least approximately determined by the first hearing aid, andwherein the determined field strength or the determined variable dependent is compared with a first threshold value, andwherein the first hearing aid is automatically switched on or off when the determined field strength or the determined variable dependent exceeds the first threshold value.

Abstract
In a hearing aid system comprising two hearing aids between which wireless signal transmission is provided. The hearing aids are automatically switched on and off. To this end, a field strength or value of an electromagnetic signal received by a hearing aid that is transmitted from the respective other hearing aid may be determined. The determined value is compared with a threshold value, the relevant hearing aid being switched off (sleep mode), as long as the field strength is greater than the threshold value and the hearing aid being switched on as long as the measured field strength is lower than the threshold value.
