Abstract : By means of a simple error propagation formula, it is shown that the usual variations in atmospheric composition may introduce an error no greater than about two centimeters per second in the computation of the sound speed and, therefore, should be of negligible concern in the routine utilization of acoustics in either sound ranging or sonic thermoanemometry.
