This is for a set of 2 aids from Hear Again, LLC in Topeka, KS. Every time you shoot a gun without proper hearing protection you are assaulting your ears with up to 150 decibels (dB) of deafening sound. Repeat exposure over 90 dB will result in permanent hearing loss while a single gun blast of more than 120 dB can do the same. More than 50 million shooters in the U.S. are currently at risk for developing some degree of noise-induced hearing lossthe worlds most common and preventable disability. These small over-the-ear devices are so light, youll forget youre wearing them! Whether you are hunting or competing in an event, the advanced technology used within our ear protection gives you a competitive advantage allowing you to hear natural sounds other shooters cannot. While wearing your hearing protection, youll be the first to hear the launch of a trap or the flush of a bird. At the same time the internal electronics immediately limit any noise over 82 dB. Weak noises are amplified tenfold and loud noises dampened to the permissible limit. You can have normal conversation in a duck blind or converse clearly with friends on the Sporting Clays course. All-the-while, your fragile hearing will remain properly protected from damaging noises such as gunfire. Save yourself from a lifetime of hearing problems or complete hearing loss with our advanced line of hearing protection products.
