The H540 Series is a high performance hearing protector and has been developed for use in extremely noisy environments. The protection is based on a technology with a double casing minimising resonance in the casing giving optimum high-frequency attenuation. An acoustic connection between the inner and outer casings provides maximum low-frequency attenuation. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure.
Other Features include:
- Effective hearing protection for noise exposures up to 105dBA.
- Noise Reduction Rating (NRR) of 33 dB Class 5, highest available in over-the-head style earmuffs.
- Represents the ultimate in earmuff technology by combining extreme noise protection with exceptional wearer comfort.
- Patented liquid & foam filled cushions provide a quality noise seal with low pressure for all day wearer comfort.
- Stainless steel headband wired with four point suspension helps distribute cushion pressure evenly & earcups pivot for consistent fit.
