The Pentagon’s Secret Scream

Sonic devices that can inflict pain–or even permanent deafness–are being deployed. “Marines arriving in Iraq this month as part of a massive troop rotation will bring with them a high-tech weapon never before used in combat — or in peacekeeping. The device is a powerful megaphone the size of a satellite dish that can deliver recorded warnings in Arabic and, on command, emit a piercing tone so excruciating to humans, its boosters say, that it causes crowds to disperse, clears buildings and repels intruders.” —LA Times
