The unique feature of sound propagation is the fact that, in the large majority of the experimental situations, it is an adiabatic process: sound velocity data give direct and precise information on the adiabatic properties of the fluid.

On the other hand pressure calibration is difficult at temperatures far from room temperature, for instance close to absolute zero. The problem of temperat
