Investigation of Experimental and Demonstrating Methods for the Measurement of the Speed of Sound from the Acoustic Resonance of Air Column, by Using the Clarinet

摘要

We have investigated the experimental and demonstrating methods for measuring the speed of sound for students. Many experimental exhibitions to calculate the speed of sound from the acoustic resonance of air column by using the clarinet, a pipe, and water filled in a bucket, were performed at various educational facilities. The estimation of each performance gave us feedback on the next practice. This method would arouse interest of (junior) high-school students and should make them have a deeper understanding in the physics of sound and the theory of wind instruments. The latest improved method demonstrated with PowerPoint presentation, was detailed in the following report.
