US Navy Develops Weapon That Could Make It Impossible To Speak


Recommended Posts



A non-lethal device developed by the US Navy aims to surreptitiously render a person unable to speak.

The device, called a handheld acoustic hailing and disruption (AHAD) system, records a target’s speech with a long-range microphone and plays it back to them with a tiny delay. 




patent filed in 2019

I knew when I used a Nagra IV and had it monitoring off the playback head if I tried to slate a scene or a head of a new roll I couldn't concentrate. A real non-leathal weapon.
