Comments on ‘‘The variation of the specific heat ratio and the speed of sound in air with temperature, pressure, humidity, and CO2 concentration’’ [J. Acoust. Soc. Am. 93, 2510–2516 (1993)]

Abstract

In the subject paper, Cramer calculated the sound speed in air at 273.15 K and 101.325 kPa based on parameters such as the ideal gas specific heat at constant pressure and the second virial coefficients of the constituents of air. Cramer underestimated the uncertainties of the above parameters and arrived at several misleading conclusions. The uncertainties in Cramer’s calculation are re-assessed and confirm that the sound speed c0=331.29 m s−1 is within the range of estimated uncertainties.
