Subsonic ammunitions are ammunitions designed to operate at velocities below the speed of sound (Mach 1), which at standard conditions is 340.29 m/s (1,116.4 ft/s). This avoids the supersonic shockwave or "crack" of a supersonic bullet, which, particularly for suppressed firearms, influences the loudness of the shot.
One of his experiments was an infrasonic whistle, an oversized organ pipe. [3] [4] [5] As a result of this and similar incidents, it has become routine in new architecture construction to inspect for and eliminate any infrasonic resonances in cavities and the introduction of sound-proofing and materials with specialized sonic properties.

Police car equipped with an LRAD-500X sonic weapon (Warsaw, Poland, 2011).. A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams.
The AA-12 (Auto Assault - 12), originally designed and known as the Atchisson Assault Shotgun, is a fully automatic combat shotgun developed in 1972 by Maxwell Atchisson. . However, the original development by Atchisson seems to have produced only a few guns at prototype-level, with the development that ultimately led to the gun entering the market being done later by Military Police Systems ...
The Whisper family was developed as a line of accurate, multi-purpose cartridges using relatively heavy rifle bullets for a given caliber in subsonic loads. [ 1 ] [ 2 ] [ 3 ] The intention was to create an extremely accurate cartridge family for military, police, competition and specialized hunting markets that could also be easily sound ...
