Hunting Hearing Aids
Hunting hearing aids are small devices that usually fit behind the ear, and connect via a hollow tube to a tip that fits into the ear canal opening. These devices then amplify ambient sound so the wearer can hear his surroundings better than he could without the device - until a weapon is fired. Then the amplifier circuit reacts instantly, limiting volume in your ear to a safe level. Once the loud sound passes, the device resumes amplifying the ambient sound.
A new type of hunting hearing aids are now available. These electronic ear plugs have no behind the ear piece or sound tube, with the ear plug doing all the work itself. Providing smart protection and enhanced situational awareness in a highly compact in-ear design, electronic ear plugs are a step up from most in-ear hunting hearing aids, and they effectively serve as the in-ear equivalent of a really high-end electronic shooter's ear muff.
Low cost hunting hearing aids generally give less hearing protection and have a lower quality of sound amplification than do more expensive digital models. In many cases hunting hearing aids offer similar performance to traditional hearing aids, but at a fraction of the cost, leading some to buy these devices as an alternative to the more expensive medical hearing aids.
