For example, if you are strong enough to tear apart a piece of plastic - it will make a distinctive sound. If you break it - it too makes a sound. Even if you tear apart paper - it makes sound. But why does this happen?
If you smash solid objects - they make sound, but this is somewhat understandable - high speed, high energy, momentum, boom and they create a soundwave.
But if you just tear something apart, for example, a piece of paper - it is less understandable.
