LRAD Sound Cannons to Deter Speeders

The LRAD first came to prominence over the last decade, as it was found to be a non- lethal cure all for riotous crowd control, and also pirate defense. Point an LRAD at someone who finds whatever your doing disagreeable, fire the sucker up, and suddenly they are blasted with up to 153 decibels of noise. Permanent hearing loss begins at 130 decibels.
