Using the mechanical resonance of continuous sound waves with frequency higher than 5 MHz, an automatic measurement system is set up for simultaneous measurements of sound velocity and attenuation coefficient in thin disk samples. It is confirmed that the change of sound velocity Δυ_s/υ_0, can be measured automatically with relative accuracy within 10^<-5> with changing temperatures at rates from 60 k/h to 3 k/h.
