ABSTRACT:
In a talk/listen headset, essentially comprising two ear protection capsules (1, 2) connected to one another via a headband (3), two microphones (6, 7) are located in one of these along a vertical (9) which runs, projected on the head of the wearer, through the middle of the temporal bone and extends up to the mandibular angle. While the upper microphone (6) acts in the area of the end of the zygomatic arch, the lower microphone (7) is located in the area of the articular process of the ascending ramus of the jaw. Both microphones (6, 7) react to solid-borne sound and are piezoelectric resonators with a mass-forming body, an impedance converter and a filter/equalizer, the microphones being connected to one another in terms of voltage in order to absorb or compensate the local tone amplitudes to the bottom and to the top caused by the reproduction. This has the effect that this indirect reproduction of the voice is optimised in terms of tone and timbre. The ear protection capsules (1, 2) also contain earphones (4a, 4b) and one receiving element (12a, 12b) each. The latter are directed towards the background noises. Microphones (6, 7), earphones (4a, 4b) and receiving elements (12a, 12b) interact with an electronic component (13) integrated in the ear protection capsules, the circuit of which component has, inter alia a communication priority in favor of the microphones and earphones and not in favor of the receiving elements.
