DI Industrial Mesh Filters, Clear Outer Casing

Industrial filters with extra high frequency protection. The DI series is designed specifically for industrial applications. Industrial noises have a tendency to be louder at higher frequencies. The DI filters have been designed to provide relatively flat attenuation to remove low frequency noise and aid communication, then a progressive attenuation increase at approximately 4 k Hz to remove irritating high frequency sounds. The filter ensures the user has air constantly flowing into the ear, reducing the occlusion effect and irritation within the ear canal to maximize user comfort. Available by the pair.
