Bilsom's new patented Air Flow Control© technology delivers optimal attenuation across all frequencies, without increasing earcup size or weight. As sound travels through the air in the earcup, a patented baseplate chamber and high-tech non-woven layer inside the ear cushion manage the flow of air and controls how sound reaches the ear. The result is better, more consistent overall attenuation for almost all industrial noise environments. Air Flow Control is a standard feature on all Leightning and Thunder series earmuffs.
