The temperatures of three model specimens placed in a 
nonheated air flow under convective and acoustic drying have been 
measured. It has been shown that in the dry specimens containing no 
water there occurs an appreciable heating of the internal region of 
the specimens by the acoustic field. The values of the moisture-exchange 
coefficients of the specimens averaged over the drying period have 
been found.
