Abstract
Acoustic signal frequency dependences were measured and theoretically calculated. A comparative analysis was carried out for measured (approximated using the Lorentzian function) and theoretically calculated dependences. It was shown that the difference between the shape of the maximum for the theoretically calculated frequency dependence and that of the conventional approximating function results in a shift of up to 1 mK in the measured absolute temperature.
