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.

Military marksmen and police units may use subsonic ammunition in suppressed rifles when minimal noise is more important than range and energy. [58]
