The loud squeaks of shoes on a basketball court result from parts of the sole slipping in pulses that repeat thousands of times a second Read Full Article #courtnoises #sneakerloops #squeakscience #basketballmotion #gameaudioeffects
👟 Physicists have discovered the "stick-slip" motion behind basketball shoe squeaks. This is a stop-and-go process where parts of the sole stick while others slide, creating regular pulses that generate the sound.
🔬 High-speed video revealed that these pulses, repeating about 4,800 times per second, alter air pressure to create the squeak. The rate of these pulses directly matches the sound's frequency and pitch.
💡 Research showed that ridges on a sneaker's tread are crucial for a clear squeak. The thickness and stiffness of the sole influence the pitch, suggesting silent shoes could be made by tuning the squeak to inaudible ultrasound frequencies.
