Popular Mechanics: The U.S. Army Is Rolling Out Superhuman Hearing to Soldiers
Wearable tech also saves troops' hearing from the din of war.
Now, the U.S. Army's PEO Soldier program has come up with the best of both worlds. TCAPS is $2,000 pair of earbuds designed to limit battlefield noise exposure, cutting off noise that reach a set decibel threshold. The wearer can still hear gunshots and estimate their direction, but the noise is dampened to a non-damaging level thanks to microphones that detect the noise, and internals that use sound canceling technology to modify it for a wearer's ears.
At the same time, the decibel cap allows TCAPS-equipped soldiers to hear the voices of others around him, including through radios and other communications equipment.
Not only is TCAPS a safety device, it's also an acoustic sensor: The same microphones the system uses to constantly detect and screen noise can be turned up to detect sounds even the naked human ear would have trouble finding.
