On Liberty Avenue Police use LRAD Sonic Weapon (Long Range Acoustic Device) to try to disperse crowd.

If you look close, there are two LRAD's; one on top of the truck (ATC LRAD 500x), and one on the back of a very large pickup truck (ATC LRAD 1000x)

I believe the 500x was used for announcements while the 1000x was wailing the siren.
