The DECx Multi-Mode Impulse Acoustic Filter is a combined impulse noise filter with a on/off switch. It was developed for the military to protect the user from gunfire, artillery noise and impulse sounds. It is also useful with industrial noise such as stamping machinery, nail guns, riveting, or jack hammers.
In the acoustic “active” mode, the DECx variable-attenuating filter starts at a NRR 18 and has been tested to as high as 166dBs for an overall noise protection performance rating of 33.7! As your surrounding noise environment increases, so does your protection level. In the “non-active” mode, the DECx will provide a NRR of 26.
The small size of DECx makes them unobtrusive and comfortable to wear, fitting easily under communications headsets or earmuffs where double protection is required.
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 minimizes the occlusion effect and reduces irritation within the ear canal, maximizing user comfort so limiting the causes of inflammation and infection.
The DECx has undergone full environmental testing for humidity, hot and cold temperatures, 12-hour comfort and sand storms. They are fully washable with water and normal detergents and suitable for all outdoor and indoor situations
