Enhanced experimental approach to measure the absolute ultrasonic wave attenuation

The absolute ultrasonic wave attenuation is an important input parameter for mathematical models, which play an increasingly important role in non-destructive testing. The measurement of the absolute ultrasonic wave attenuation however is a difficult task. When conventional measurement techniques are applied, corrections to the raw data are required to account for apparent losses. In this study, a modified experimental approach is proposed to determine the absolute ultrasonic attenuation without any further corrections of the raw data.
