Tiny microphones fitted in army helmets to reduce risk of hearing injuries

Tiny microphones almost invisible to the naked eye are being knitted into the fabric covering army helmets to help reduce the risk of soldiers developing hearing injuries.

Research by Nottingham Trent University helped develop the technology to measure and record the levels of noise which soldiers experience in the field to prevent hearing damage.

The microphones, when knitted into the fabric covering regular personnel headwear, will be undetectable to the user and avoid interfering with military activities.
