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, or Tactical Communication and Protective System, and about 20,000 of the new TCAPS devices have been deployed in the field so far.
