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?

    Yeah. But the frequency of the sound has to match the resonance of the glass. Any sound can break any glass if they resonate strongly enough to make the glass vibrate violently enough to break. This is pretty hard to do, even when you can control the acoustics of the sound being using to shatter the glass (IE when a singer breaks a wine glass). Finding the right gun and right glass to make it work would be like finding a needle in a haystack.

    Using a large enough gun that creates a sonic boom I’m not sure counts. It’s not the sound itself that is breaking the glass at that point, but the concussive force of the wave traveling at high speed.

      Guns would break glass by essentially turning air into a hammer rather than resonance. Also lots of rifles are capable of firing bullets that make sonic booms, it’s just not that powerful when it’s a tiny bullet.

      Basically every modern cartridge is supersonic unless they’re specifically underpowered to make them subsonic.

      The smallest thing you’re going to regularly encounter is .22 LR- for context this is the kind of thing you’d use to hunt very small animals- and even that straddles the line of super/subsonic.

      Basically what I’m getting at is that it doesn’t need a “large gun”.
