In a hearing aid device system with a hearing aid device which can be worn on or in the left ear of a user and a hearing aid device which can be worn on or in the right ear of the user for the binaural supply of the user, the aim is to reduce feedback tendency. To this end, it is proposed to transmit audio signals resulting from the microphone signals of the hearing aid devices in a crosswise fashion between the hearing aid devices and thus to emit an acoustic signal recorded by the microphone of a hearing aid device, after the signal processing and amplification, by means of the receiver of the respective other hearing aid device. In this way, the distance between each receiver and microphone, between which a feedback path exists, is essentially increased for the relevant audio signals.

Method for operating a hearing aid device system for the binaural supply of a user

The invention relates to a hearing aid which, with the aid of an integrated positioning unit or a positioning unit integrated in a mobile activation device automatically sets operating parameters of the hearing aid as a function of the location of the hearing aid or of the activation unit.

Method for setting a hearing aid, hearing aid and mobile activation unit for setting a hearing aid

Directional hearing is improved given the binaural coverage for a hearing aid user with two hearing aid devices wearable at the ears. The respective signal transit times and/or signal amplitudes and/or amplifications of an electrical signal are respectively measured in a signal path between an input transducer and an output transducer and that data with respect to the measured signal transit times and/or signal amplitudes and/or gains is transmitted onto the respectively other hearing aid device. As a result, the signal transit times and the signal amplitudes of the electrical signals through the two hearing aid devices can be matched to one another. The hearing aid devices thus cause no phase or amplitude distortion, and the natural phase shift as well as the natural amplitude difference of a sound signal incident from a specific direction are thus preserved. The directional information is thus also preserved for the hearing aid user.
