- Long-range acoustic device - Wikipedia
A long-range acoustic device (LRAD), acoustic hailing device (AHD) or sound cannon is a specialized loudspeaker and sound weapon that produces sound at high power for communicating at a distance

Review the basics of sound and discover exactly how the LRAD produces its "beam of sound " We'll also explore LRAD's hailing and warning abilities and other uses for sound
- The Sound Engineering Behind LRAD Technology - GraySpark Audio
The directional acoustic beam formed by an LRAD (typically 15-30 degrees) employs the same wave physics principles that sound designers use for line array systems in concert venues, but with specialized optimizations for extreme distances and intelligibility
