The Long Range Acoustic Device (LRAD) is powerful enough to cause permanent auditory damage and has been used for the first time on USA streets.
The device was originally intended to be used by American warships but it is now being used for crowd control by the US Government. These devices are also currently used at Camp Bucca, Iraq, and are being tested in regions of Baghdad, Fallujah, along with other regions of Iraq.
According to Foreign Policy magazine, LRADs have been sold to the government of the People’s Republic of China, even thought American companies can not sell weapons to China since the Tiananmen Square massacre.
