Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the speed of sound.
Sonic if at a distance...
It is a bullet for a .22 caliber rifle which is very quiet as the bullet travels slower than the speed of sound
Some do, some don't. The bullet from a .45ACP is subsonic. There are a number of planes that fly at supersonic speeds.
A wadcutter is a special-purpose bullet designed for shooting paper targets, usually at close range and subsonic velocity.
Depends on the range at which the rifle is zeroed.
It depends on a couple of factors, but it can range from none (on a subsonic round) to a couple of grains.
The antonym for subsonic is supersonic.
They are actually quieter than supersonic bullets. When a gun is fired, noise comes from 3 sources- the main one being the sudden blast of gasses that are released from the muzzle as the bullet leaves. That still exists with subsonic bullets- they are just traveling slower than the speed of sound (ABOUT 1200 feet per second) The second part of the noise is from the bullet breaking the sound barrier- a high pitched CRACK sound. Subsonics do not do that. Third part of the sound is from the action of the firearm extracting the fired cartridge, and loading a new one.

Supersonic
Transonic being past the speed of sound and subsonic is below the speed of sound.
