Abstract

Ultrasonic wave attenuation (α) measurement by pulse-echo method exhibits pronounced dependence on experimental conditions. It is shown to be an inherent characteristic of the method itself. Estimation of α from the component wave amplitudes in the frequency scale gives more accurate and consistent value. This technique, viz., the Fourier spectrum pulse-echo (FSPE) is demonstrated to determine the ultrasonic velocity (v) and attenuation constant (α) in ultrapure de-ionized water at room temperature (25 °C) at 1 and 2 MHz wave frequency.
