EarPro, recently acquired by SureFire LLC, introduces a passive hearing protection system, the EP-3 Sonic Defenders. Sonic Defenders are designed to help prevent hearing damage from noise above 85 decibels while facilitating conversation by permitting passage of lower-level sounds. The use of a proprietary design incorporating the patented Hocks Noise Breaker filter enables the Sonic Defenders to convert the energy from harmful sound levels into insignificant amounts of harmless heat energy. In addition to being more comfortable than common foam plugs, Sonic Defenders don't muffle ambient sounds or compromise directional hearing nor do they require a visit to a specialist for a custom fitting.
