subsonic
Speed has nothing to do with where you are. You can travel below the speed of sound pretty much anywhere.
The antonym for subsonic is supersonic.
Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the speed of sound.

A subsonic aircraft doesn't produce a sonic boom because it is subsonic, and cannot produce enough speed to do so. A sonic boom is created when an aircraft becomes supersonic, accelerating past the speed of sound. Since it is traveling near the speed of sound at this time, the sound waves build up around it, finally traveling through the air as it is left behind by the aircraft.
The main difference is the speed of the object in relation to the speed of sound. Subsonic refers to speeds slower than the speed of sound, while supersonic refers to speeds faster than the speed of sound. In the case of supersonic speeds, objects are traveling faster than the speed at which sound waves propagate in the medium.

Subsonic flow is commonly used in various engineering applications, such as in the design of aircraft wings, wind turbines, and ventilation systems. Understanding subsonic flow is crucial for optimizing the performance and efficiency of these systems.
subsonic is moving below the speed of sound, supersonic is faster than speed of sound
Subsonic speed refers to speeds below the speed of sound in a medium. In water, the speed of sound is higher than in air, so typical speeds of objects moving through water are considered subsonic.
