Technologies

An expert in acoustics and electronics since 1927, the ELNO Group boasts an extremely dynamic R&D department. The Group is constantly innovating, supporting its customers and helping them reach their goals in France and throughout the world.
ELNO does not only specialise in traditional electro-acoustics. Its expertise also lies in sophisticated patented technologies such as AAB (Atténuation Active de Bruit or Active Noise Attenuation) and bone conduction (osteophony), and the Group is also developing systems involving IP network technologies.

 

 



ANR - Active Noise Reduction
ANR - Active Noise Reduction
  • 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 earplugs, the double protection provides the advantage of being protected against impulse noises (shots) as well as transients (missile departures).

    • Cartilaginous sound conduction
    • Microphone ambiant noise reduction
    • Noise reduction using double protection
    • 3D TalkThrough® three dimensions external listening
    • Ergonomic equipment
    • Optimization of passive mode noise protection
