When a balloon pops, what is actually creating the sound I hear?
In: Physics
Think of air as a spring that goes in all directions – the air in the balloon is compressed, while the air outside the balloon is not (well, it’s less compressed). When the rubber breaks, the inside spring expands and causes the outside springs to compress as it does so. This will oscillate a bit until equilibrium has been settled upon, and these oscillations in the air are what we perceive as sound.
