We all know exactly what those squeaks sound like. It has a unique sound, and a characteristic frequency. What is it that makes rubbing of the sole against the court produce such a characteristic sound, so different to other friction sounds such as a shoe sliding across a normal pavement?<\/p>\n<p><iframe loading=\"lazy\" title=\"USA Basketball Training for the 2012 London Olympics\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/nR2cpQs-ETA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><strong><span style=\"font-size: 10pt;\">Squeaking sounds are an inseparable part of the game\u2019s soundtrack. (USA Basketball national team practice ahead of the 2012 London Olympics)<\/span><\/strong><\/p>\n<p>A recent study [1] took this question seriously. The researchers recreated the squeaking sound made by a basketball shoe sole sliding over a smooth surface, recorded the sounds, and filmed the contact region between the sole and the surface. Video footage of the contact region between the basketball shoe sole and the surface reveals a complex dynamic of contact and separation as the shoe slides. The shoe clearly slides forward uniformly, but some parts of the contact region detach while others adhere to the surface. This cycle of detachment and contact is known as detachment waves.<\/p>\n<p><iframe loading=\"lazy\" title=\"Gym Shoes Squeak Because of This Physics Phenomenon\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/syVweYvqsz8?start=22&amp;feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><strong><span style=\"font-size: 10pt;\">In this video from the researchers\u2019 experiment, detachment waves between the shoe sole and the sliding surface can be seen on the left.<\/span><\/strong><\/p>\n<p>Imagine a detachment wave, it's like dragging a heavy rug across the floor. The \u201cbrute-force\u201d approach is to pull the rug from one end while struggling to drag along the floor. An easier way to do this is to shake the rug by quickly lifting and lowering the side you are holding. This creates a vertical wave in the rug that travels away from you in the opposite direction to the pull. The rug will move towards us in the section of the rug that is lifted off the floor at that moment, that is, where the wave passes. This is a detachment wave that is larger than those formed in a sports shoe sole. It is designed to make dragging the rug easier.<\/p>\n<p>Similarly, detachment waves allow the sole to move across the surface. In fact, the shoe\u2019s seemingly smooth, uniform motion across the surface takes place in a series of strip-by-strip detachment waves.<\/p>\n<p>The phenomenon of detachment waves has been recognized for several years as a mechanism by which two materials with different elastic properties can slide over one another [2]. This phenomenon is also sometimes observed in earthquakes, when ground motion advances in the form of a pulse, essentially, a large detachment wave. This occurred in the famous 2015 Gorkha earthquake in Nepal. This powerful magnitude-7.8 earthquake caused widespread destruction and claimed many lives. Analysis of the ground motion after the earthquake revealed that the tectonic structure in the region produced a 20-kilometer-wide pulse in the ground that traveled for about 140 kilometers. This is contrary to the traditional rupture model where the two sides of a fault slide continuously past one another.\u00a0 In practice, it was an enormous detachment wave [3, 4].<\/p>\n<p>We can now see that detachment waves are also responsible for the familiar squeaking sound. Since these waves only form when the sole is dragged across a smooth surface, the squeak can be heard on a hardwood basketball court, but not on a dusty outdoor concrete court.<\/p>\n<p>The frequency of the squeak is determined by the density and speed of the detachment waves. But what determines the density of these waves? In order to characterize the properties of the waves precisely, the researchers prepared rubber samples with different groove patterns, essentially \u201csole samples\u201d, as well as smooth samples. Images of the surfaces and recordings of the resulting squeaks showed that smooth patterns produce irregular detachment waves of different sizes traveling in different directions. Accordingly, the sound produced does not have a particular characteristic frequency, but rather consists of many frequencies of similar intensity, much like white noise. In contrast, the patterns with orderly grooves produced regular detachment waves, generating sounds with several distinct frequencies. Together, these create the distinctive, familiar squeak.<\/p>\n<p>The phenomenon whereby grooved surfaces produce distinctive sounds when slid across, while smooth surfaces produce noisier sounds, is also familiar from everyday life. Try dragging your finger across a smooth surface, such as a window, with your fingerprint ridges facing downwards. Compare this with the sound produced by dragging the heel of your palm across the same surface. You will probably notice that dragging a finger produces a more distinct squeaking sound, whereas dragging the heel of the palm produces a duller sound. In the study, the researchers quantitatively measured precisely this difference.<\/p>\n<p>The researchers characterized the relationship between sample dimensions and the sound produced using several rubber samples and sole samples of different dimensions. In principle, this makes it possible to engineer patterns that produce precise, tuned musical sounds when rubbed against a smooth surface.<br \/>\nA study of this kind would not be complete without a symphony of squeaks.
