3D printed ring cuts sound by 94%

How about usng the design for ear plugs or ear muffs? If they can reduce the size.

That's a great idea! And something the plastic should be able to withstand with ease

[Gun]

A speaker and a vun shot are way different. The volume of expanding gas compared to the acoustic wave from a speaker propagates sound quite differently. Maybe as an adjunct to a suppressor after the violence is subdued.

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.
