Re: 3D printed ring cuts sound by 94%
It's the volume of gas expanding faster than the speed of sound that gives you the report of the gun fire, much like the crack of a whip.
Sound from speakers travel at the speed of sound in the media the wave propagates.
The application (in the vid), for right now, seems to apply to a limited frequency, one encountered in industrial machinery.
