Army’s Smart Earplug Damps Explosive Noise, But Can Enhance Whispers
Since 2014, the U.S. Army has gradually been deploying the latest version of a hearing protection system that protects users from loud noises while still letting them hear the world around them.
The system is called TCAPS — Tactical Communication and Protective System — and about 20,000 of the new TCAPS devices have been deployed in the field so far.
Hearing loss is a big problem in the military. According to Defense Department statistics, more than half of all troops returning from Iraq or Afghanistan suffer from some sort of damage to their hearing.
