Long Range Acoustic Device (LRAD) (body worn (i.e. over shoulder) (left) / embedded in a riot control shield (right))

Technical Info:
Emits a “deterrent tone” to disperse a crowd or can be used as a mega phone-type device to convey instructions over a large area.
Can be free-standing, vehicle-mounted, embedded in a riot control shield or body-worn (i.e. over the shoulder).

Concerns:
Indiscriminate – not targetable at an individual – affects innocent bystanders.
Risk of permanent hearing damage, ear drum rupture, loss or equilibrium / balance.
