PCMsoundie Posted September 8, 2021 Report Share Posted September 8, 2021 Quote 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. https://www.newscientist.com/article/2287973-sneaky-us-navy-feedback-device-could-stop-people-being-able-to-speak/ patent filed in 2019 a better photo is here. 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.
