Why do some shoes squeak on some surfaces but not others?
In: Physics
the squeak is caused by the rubber of your shoe dragging on a surface, and then losing grip and going back into shape. It would normally sound like a dull thud as would any other thing when it hits a big solid surface like the ground. In the case of a squeak it’s often that this cycle happens so fast that it can produce enough thuds to form a sound wave with a pretty well defined frequency. This happens usually when you see wet shoes on slick surfaces because the shoe is no longer able to maintain traction.
