Swatcom SC21 Pro Impulse Universal in ear hearing protection

SWATCOM SC21 Pro Impulse are reusable ear plugs designed to reduce loud noises to safe levels. The ear tip design provides a comfortable and discreet fit, and instead of blocking noise which leads to a muffled sound, the filter reduces noise levels allowing you to hear both safely and clearly.

The Pro Impulse filters provide a constant 15dB (SNR) reduction, but can react to sudden loud noises (such as gunshot) to provide a brief higher level of protection before returning to the normal constant level.


For higher levels of noise protection the PRO Impulse can be worn in conjunction with over-ear headsets.

The new universal fit version with soft in-ear tips is now available for ‘off the shelf’ convenience.

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 so limiting the causes of inflammation and infection.

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.

ANSI IPIL certified impulse protection is 33.1 dB maximum.

Please ensure that a noise assessment is carried out on site before purchasing your hearing protection as it is imperative the correct protection level is used.
