The effect is also noticed on frequencies above and below human hearing, providing a significant gain over a wide window of frequencies The transducer used now is a special issue unit that has considerably more sound pressure level than standard units. The 12" aluminum parabolic dish increases the amount and sensitivity of collected sound (increases the reception of fainter sounds, or those from a longer distance), and provides more of a directional target location. Some articles suggest the drivers inside the device use piezoelectric transducers, which convert electrical impulses to high-speed vibrations, emit sound waves in the ultrasonic range. Military officials asked the LRAD Corporation (now Genasys) for a device with two functions: to communicate at a distance with potential threats, and to disperse them with an unbearable alarm-like sound.
