High Precision Method of Measuring the Velocity of Sound With Simple Apparatus
Hansen, Russell C.
Physics Teacher, 13, 2, 101-105, Feb 75
A capacitor is discharged to generate an acoustical pulse and start a digital counter which is stopped by a microphone. Differences are accurately measured by positioning the sensing microphone on an optical bench. Results are discussed and extended experiments are suggested. The sources of some components are given.
