Navy Device Prevents People From Talking – Nonlethal Weapon

Source: The Navy Invented a Device to Prevent People From Talking

The U.S. Navy has invented a new device to prevent people from speaking, one that people with siblings will recognize instantly. The handheld acoustic hailing and disruption device records a person’s speech and spits it back out again, disrupting their concentration and discouraging them from speaking further. Although an interesting—and very familiar—concept it’s unlikely this tech will ever see use on the battlefield.
