ANR - Active Noise Reduction

The principle behind ANR lies in the destructive wave theory. An out-of-phase noise is superimposed over the undesirable noise to cancel it out.
With ANR headphones, an electronic system is connected to a microphone that captures ambient noise and a speaker that generates the out-of-phase noise.

  • 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).
