Why do balloons make a ‘bang’ sound when they’re popped?

When I watch a balloon pop in slow motion, the material appears to tear and contract instead of exploding. It seems like if it were to make any sound then that sound should be a tearing sound.

It’s not the rubber skin making the sound. It’s the compressed air inside that is suddenly released and expanding in all directions that you hear.
