Abstract: The preferred direction of a directional microphone of a hearing device and, in particular, a hearing aid should be selected automatically in a quick and reliable fashion. To this end, provision is made for a method for operating a hearing device with such a microphone which can be switched into at least a first and a second directional characteristic. Initially, respectively one signal-to-noise ratio is determined for the first and the second directional characteristic. Subsequently, the directional microphone is switched into that one of the two directional characteristics which leads to the higher signal-to-noise ratio. In particular, the total signal powers of different directional microphone signals can be determined to this end and the interference signal powers can be calculated in parallel thereto in a channel-specific fashion. Corresponding SNR values then result from the differences in the logarithmic power values.

Abstract: The acoustic radiator of a coaxial structure of an active region surrounded by a passive region wherein the operating area of the active region is also included as a part of the passive region. The active region includes for example a fully assembled audio speaker that is flexibly suspended in an enclosure with the flexible suspension connected between the audio speaker and the opening of the enclosure with the audio speaker never coming into direct contact with any portion of the enclosure when energized or unenergized. In such configuration, the area of the audio speaker functions as active region the audio speaker of the acoustic radiator. The passive radiator function includes both the area of the complete audio speaker and the area of the enclosure that surrounds the audio speaker. In this configuration the audio speaker is a central portion of the passive radiator and thus it can be seen that the audio speaker and the passive radiator are effectively coaxially mounted one with the other.
