ViTac™ NRF
Noise Reduction Filters

Protect Your Hearing Whilst Allowing Situational Awareness In The Cluttered Digital Battlefield. 

ViTac™ Noise Reduction Filters (NRF) provide protection from a variety of impulse sounds including:
  • Automatic Fire
  • Single Gun Shots
  • Artillery Fire
  • Armoured Fighting Vehicle (AFV) Operation

 

Crucially when sound peaks are not present, ViTac™ NRF allows ambient sound to travel through the filter straight into the ear, ensuring voice and background noise can be heard, whilst maintaining directional hearing with the minimum occlusion effect.

 

This unique filter technology retains spatiality and sound directionality in critical operational or combat situations in the field.

ViTac™ - Noise Reduction Filters
 

Developed for Military use, ViTac™ Noise Reduction Filters use an ANSI IPIL certified filter (ANSI/ASA S12.42-2010) for shocks up to 166 dB, providing up to 33 dB of attenuation.

This unique filter technology retains spatiality and sound directionality in critical operational or combat situations in the field.
