"Squeaking occurs across various contexts including shoes, bike brakes, rubber tires, and biomedical implants when soft and hard surfaces contact each other. Researchers used high-speed photography to study a rubber block sliding across hard acrylic to identify the source of these sounds. The investigation revealed that pulses similar to earthquake dynamics drive the squeaking phenomenon."
"Tiny bolts of lightning initiate the pulses that cause squeaking when rubber slides across hard surfaces. Understanding this mechanism has potential implications for advances in engineering, metamaterials development, earthquake research, and potentially new musical instrument design."
