The new PRO Impulse filter has been specially developed to reduce sudden high volume sounds from being transmitted to the inner ear, giving the wearer protection when they need it while allowing normal hearing at all other times.
The filter gives a constant noise reduction of approximately 15dB, increasing to a maximum of 33dB when activated by sudden high noise. For higher levels of noise protection the PRO Impulse can be worn in conjuction with over-ear headsets.
The small size of Impulse filters makes them unobtrusive and comfortable to wear, fitting easily under communications headsets or earmuffs where double protection is required.
Developed for military use the Impulse filter protects hearing from gunfire, artillery noise and impulse sounds from nail guns, drop hammers and riveting. Designed to allow air to enter the ear, this unique filter technology retains spatiality and sound directionality as required in hunting and combat situations. Unlike competing products this ventilation minimises the occlusion effect and reduces irritation within the ear canal, maximising user comfort.
The Impulse filter has undergone full environmental testing for humidity, hot and cold temperatures, 12-hour comfort and sand storms. Fully washable with water and normal detergents, Impulse is suitable for all outdoor and indoor situations. The Impulse filter with custom mould has a constant noise SNR value of 15dB (estimated), suitable for continuous safe use to 100dB.
