Bone conduction

The bone conduction is the phenomenon of distribution of the sound up to the internal ear via the bones of the skull.

Listening is carried out directly by the vibrations of the skull, and thus overcomes the passage through the auditory canal, it is called "bone conduction headphones."In the same way the voice is transmitted to a vibration sensor that detects vibration of the jaw bone, it is called "bone conduction microphone."

This principle is covered by patents in France, in Europe and in some countries outside Europe such as North America and some Asian countries.

The advantage is that the user does not have the ears plugged, or mouth obstructed by a microphone. He keeps in touch with the immediate environment, can be understood in a noisy environment, can use a mask or even use it underwater.

  • HOPLITE - CARTILAGINOUS CONDUCTION STEREOPHONIC HEAD-MOUNTED EQUIPMENT

    HOPLITE provides a high level of ease of use and passive protection thanks to its ergonomic ear pads and allows communication in noisy environments. Cartilaginous conduction offers the operator the possibility of using ear plugs for double hearing protection in very noisy environments.
    Thanks to active noise attenuation (ANR), the noise level is considerably reduced (especially: low frequencies).
