The ultrasonic spectroscopy (broadband pulse) technique was applied to simultaneously measure phase velocity and attenuation coefficient of shear waves in a solid in the megahertz frequencies. This technique is an extension of the ultrasonic spectroscopy technique currently used in determining dispersion of longitudinal waves. Sources of error in measurements including diffraction loss and nonlinear distortion will be discussed. [Work supported by Hewlett--Packard Co.]
