Chladni Patterns on Drumheads: A "Physics of Music" Experiment
Worland, Randy
Physics Teacher, v49 n1 p24-27 Jan 2011
In our "Physics of Music" class for non-science majors, we have developed a laboratory exercise in which students experiment with Chladni sand patterns on drumheads. Chladni patterns provide a kinesthetic, visual, and entertaining way to illustrate standing waves on flat surfaces and are very helpful when making the transition from one-dimensional systems, such as string and wind instruments, to the two-dimensional membranes and plates of the percussion family. Although the sand patterns attributed to Ernst Florens Friedrich Chladni (1756-1827) are often demonstrated for this purpose using metal plates, the use of drumheads offers several pedagogical and practical advantages in the lab.
