How loud does a sound have to be to break stuff?
Let's say we're trying to break a glass wine under 30 seconds with pure sound. Let's also assume that the sound we're emitting perfectly matches the glass's frequency (resonance). Approximately, how loud should the sound be in db? Maybe 100?
Another question: Do small, handheld electronics like iPhone or Nintendo 3DS break easily from sound like glass does?
It would have to be a LOUD SCREACH like a little girl going AHH times 10
Your ears would pop kid

- Why does my iPhone 5s play music out loud, even on silent? When the switch on the side of my phone is switched to silent (red bar showing), my phone will still play music, videos, or sounds from apps out loud unless I turn the volume all the way down using the volume buttons. I thought the silent switch was supposed to prevent any sounds.
- Why Do I Have To Click The Sound Thing On Instagram To Play The Sound? For some reason the sound hasn't been working on my iPhone for Instagram. Someone said to click on the moving sound bars on the top right of the video and that it will play sound. Well, it worked. But my question is why the hell should I do that? Can't it just automatically play?
