We proposed a method for determining accurate acoustical physical constants at wide temperature range by combining the resonance method with the UMS technology taking LTGA single crystal. Obtaining the accurate constants and their temperature coefficients by the UMS technology even for narrow temperature range around room temperature, we demonstrated that we were able to calibrate the resonance method and to conduct more reliable determination of constants.
