The Navy wants to weaponize your own voice against you
The Navy may have a new non-lethal weapon to play with sooner rather than later.

A Navy engineer has developed a new non-lethal device designed to render targets incapable of speech by turning their own voice against them, according to a new patent application.
Invented by Christopher A Brown of the Naval Surface Warfare Center – Crane Division near Bloomington, Indiana, and patented in late June, the so-called ‘acoustic hailing and disruption’ (AHAD) system is elegant in its simplicity. The device records incoming voices, amplifies them, and plays them back in two distinct sounds, one “nearly simultaneously” with the original speech and one on an ever-so-slight delay.
The result is what’s called delayed auditory feedback, which refers to the delay between speech and hearing one’s own voice. Normally, the human body is used to the phenomenon, but when deployed at the right interval by the device, the delayed auditory feedback “alters the speaker’s normal perception of their own voice” and confuses the speaker — not unlike, say, the disorienting experience of trying to talk over on the phone while someone else talks over you.
