Correspondingly, what causes the sound of a gunshot?
The hot gas pushing the bullet out of the barrel is at very high pressure (11000 to 55000 pounds per square inch). So the gas exits the muzzle with explosive speed and pressure creating a “blast” of sound waves of very short duration.
Also, what sound does a gun make onomatopoeia? “BAM,” “BOOM,” “BANG” and “POW” are used to convey the sound of a gunshot in English.
Subsequently, question is, what is the sound of a gun called?
A gunshot is a single discharge of a gun, typically a man-portable firearm, producing a visible flash, a powerful and loud shockwave and often chemical gunshot residue. The term can also refer to a ballistic wound caused by such a discharge.
What determines how loud a gun is?
It would seem that it's the pressure in the barrel at the time the bullet leaves the muzzle that determines how loud a gun is.
