Active hearing protection utilizes sound dampening technology that can work independently or with passive methods to reduce noise levels for users. Active noise reduction works well with frequencies below 500 Hz and passive takes over for frequencies above 500 hertz.
Active noise reduction comes to play to protect hearing against possible damage from sudden, sharp sounds. These range from barking dogs and talking people, to other music sounds that vary from moment to moment. Active noise reduction works best with a continuous sound that maintains the same pitch for an extended period, so that the system can intercept and effectively block it. Our solution for this is Hunter-1 and Active Guard. In addition to noise cancellation, it protects the hearing from impulse noise above 85 dB spl.
