Story summary
- The study, led by Professor Katia Bertoldi and her team, analyzes the squeaking of basketball shoes on polished courts to reveal friction mechanics.
- They filmed the shoe–surface interaction and found that the squeak pitch correlates with the sole's stiffness and thickness.
- Ridged soles produced consistent sounds, whereas smooth surfaces yielded irregular noises.
- Future research will explore how complex surface textures affect friction and acoustic output.
