Abstract
The expected influence of humidity on the speed of sound in standard atmospheric air at various temperatures is presented. The prediction is based on theoretical [G.S.K. Wong and T.F.W. Embleton, J. Acoust. Soc. Am. 76, 555–559 (1984)] and experimental [G.S.K. Wong and T.F.W. Embleton, J. Acoost. Soc. Am. Suppl. 1 76, S65 (1984)] data obtained for the variation of the ratio of specific heats γ in humid air. Over a temperature range from 0° to 30 °C, the maximum uncertainty on the sound speed ratio ch/c0, is estimated to be less than 400 ppm; where ch and c0, are the sound speed in humid and in dry air, respectively. Comparisons are made with known experimental measurements and theoretical data.
