VISCOELASTICITY CHARACTERISTICS MEASURING APPARATUS AND VISCOELASTICITY CHARACTERISTICS MEASURING METHOD

PROBLEM TO BE SOLVED: To provide a viscoelasticity characteristics measuring apparatus and a viscoelasticity characteristics measuring method, capable of efficiently measuring viscoelasticity characteristics, by suppressing the influences due to the temperature dependence of acoustic waves. SOLUTION: A reference data memory section store a two-dimensional reference data set, specified by the delay member temperature and the elapsed time from a reference point that is the start timing at which incident acoustic waves are emitted. A corrected reference data determining section decides the corrected reference data, corresponding to the temperature measurement value of the delay member which is measured by a temperature measuring section, based on the reference data set of each of temperature of the delay members stored in the reference data memory section. As an example, the corrected reference data determining section determines a corrected reference data set from among a plurality of reference data sets stored in the reference data memory section, which has a corresponding delay member temperature that is closest in value to the measured temperature value.
