The velocity of sound in liquid n-tetradecane has been studied 
experimentally in the interval of temperatures from 303 to 433 K and pressures
to 100 MPa. The maximum measurement error amounts to 0.1%. Experimental 
data on the velocity of sound in liquid n-tetradecane in the region 
of the state variables p = 50-100 MPa and T >> 373 K have been obtained 
for the first time. It has been shown that the new data demonstrate the 
reliability of the structure-property quantitative correlation proposed 
earlier for the acoustic quantity in the series of n-alkanes.
