Direct Measurement of the Speed of Sound Using a Microphone and a Speaker
Gómez-Tejedor, José A.; Castro-Palacio, Juan C.; Monsoriu, Juan A.
Physics Education, v49 n3 p310-313 May 2014
We present a simple and accurate experiment to obtain the speed of sound in air using a conventional speaker and a microphone connected to a computer. A free open source digital audio editor and recording computer software application allows determination of the time-of-flight of the wave for different distances, from which the speed of sound is calculated. The result is in very good agreement with the reported value in the literature.
