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.



ANR - Active Noise Reduction

    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 earplugs, the double protection provides the advantage of being protected against impulse noises (shots) as well as transients (missile departures).
