Can a gun break glass with just sounds alone?

vis4valentine@lemmy.ml to No Stupid Questions@lemmy.world – 75 points –

I was thinking about how fire guns are very loud and how its worst in close environments (I had never shot a gun cuz im not american) and I remembered the Mirror room scene in John Wick Chapter 2.

I was thinking if by shooting once, many mirror could break because of the sounds of a gun alone. Has someone tried this or see it happen?

Sound waves are energy traveling through the air. Energy is what causes stress, strain and failure in materials. Yes, a loud gun, especially at the right frequency, could break things with a relatively low failure point.

Explosions frequently break glass and a gunshot is basically a small, controlled explosion.

Small being the operative word. Gunshot explosions don't have enough energy to break glass in most circumstances.

I think you are assuming a lot of things here. Modern guns and modern glass, for instance.
