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.

  • FPH500 - Fighter pilot helmet

    FPH500 provides the highest level of protection and communications which is required by the fighter’s crew.

    • 2 integrated visors
    • Wide field of view
    • Optimized center of gravity
    • NVG usable with 2 visors
    • Accepts main types of NVG’s
    • Available receptacles for different O2 masks
    • ELNO communication kit for noisy environment

  • 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).
