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.
Some do, some don't. The bullet from a .45ACP is subsonic. There are a number of planes that fly at supersonic speeds.
Subsonic signals are sounds or vibrations that have a frequency lower than that which may be heard by the human ear as a discernable tone. Vibrations lower than 30 Hz (30 cycles per second) are considered subsonic.
Subsonic is below or slower than the speed of sound, and supersonic is above or faster 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.
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.
The .45 is a naturally subsonic round, and can be suppressed quite easily. However, you will still hear the noise of the action being worked as the weapon is fired, which will be very audible.
Because the bullet shoots out and let's a big bang of pressure

Loud. This is because there is much more gunpowder involved and all the components in the "bullet" are not in a case so it allows the sound to travel more.
