3M Peltor ComTac III MT17H682FB-47 SV. Shooting Range, Military Tactical, Shooting, Hunting. Talk-Through Level Dependent Functionaility, commonly referred to as talk-thru, is a means of allowing safe audio sounds to bypass the individual hearing protection while still protecting against harmful noises. This can be accomplished with a proprietary digital audio circuit integrated into the headset. A microphone will receive sounds outside its headset and transmit those to a speaker inside the headset. This Level Dependent Digital Audio Circuit easily senses noise levels above the desired threshold and compresses each to a safe decibel level or amplifies weak sounds to an audible level. Clipping 3M has incorporated compression technology to remove the clipping effect heard in common talk-thru systems. Clipping can result in missing the first syllable of important commands. This technology resolves that issue and dramatically improves speech intelligibility. Fail Safe ComTac External Communication i. Radio or intercom and talk thru are completely independent of one another. In the unlikely event of electronic failure or battery depletion, external communications will continue to function.
