hearing

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.

New research out of the University of Washington finds hearing-impaired kids can train their ears and brains to hear better in a noisy classroom. Students with limited hearing have an especially tough time making out what someone is saying if, say, kids in the back are whispering, or a classmate has a cough.
