Measure Speed of Sound in Air Using Cross Correlation with white noise or MLS

This video demonstrates how to measure the speed of sound in air using cross correlation. Continuous white noise, MLS and sine waves as well as their burst types are used respectively as the test signals. Their differences are shown. The robustness of this measurement method is demonstrated.
