San Jose police are to begin using high tech sound wave weapons that are designed to disperse crowds by firing concentrated beams of sound at 150 decibels, causing intense pain and possible deafness.

The police department is to get $27,000 in state grant money to purchase the device, which is the exact same model used by armed forces against insurgents in Iraq and Afghanistan.

The dish-shaped, sonic weapon is officially called a Long Range Acoustic Device — or L-RAD.
