Abstract
A portable device for accurately measuring acoustic velocities in solids. This portable hand-held device (100) uses dual receiving transducer tips (110, 112) to allow differential measurement of acoustic velocity in a solid. A body having a handle uses a transmitting transducer tip (108) to transmit acoustic energy to a solid. The first receiving transducer tip (110) is used in conjunction with a second receiving transducer tip (112) mounted on the body a fixed distance from the first (110). The device (100) uses the differences in the time of arrival of the wavefront at the first and second transducers to calculate the acoustic velocity in a given solid. This differential measurement method reduces acoustic velocity measurement inaccuracies.
