Abstract
An ultrasonic measurement apparatus () estimates a property/state of a test object () that allows an injected ultrasonic wave to propagate as plate waves (UW) of propagation modes. The ultrasonic measurement apparatus () includes: a receiver () configured to receive a detected signal obtained by detecting the plate waves (UW) propagating through the test object () to output a received signal indicating a time-domain waveform of the detected signal; an intensity detector () configured to detect the signal intensity of a waveform part corresponding to a first propagation mode, and the signal intensity of a waveform part corresponding to a second propagation mode; and an estimator () configured to make a comparison between the signal intensities to estimate a property/state of the test object () on the basis of a result of the comparison.
