[efoods]Vancouver police have a new crowd control device capable of emitting painfully loud blasts of sound, just in time for the 2010 Winter Olympics, CBC News has learned.
The long range acoustic device (LRAD) can use sound as a weapon, emitting levels that cross the human threshold of pain and are potentially damaging to hearing. But it is also designed as a communications device that’s clearly audible up to a kilometre away.
Const. Lindsay Houghton said the device was first tested this summer as a public address system during the Celebration of Light fireworks events in Vancouver.
