Abstract
In a sound velocity measurement in solid, the properties of electrical source and ultrasonic transducer bonded to a solid material become the error sources. In this paper, the error sources are estimated from the simulation using transmission line model of a measurement system and their experiments. A novel method for correcting the measured values of sound velocity by a numerical fitting is suggested. The usefulness of our method is demonstrated by comparing with other methods. Sound velocity measurement with the accuracy better than 1% without regard to the electrical and mechanical effects or bonding layers effects have been successfully accomplished.
