Abstract
A novel solution of measuring the acoustic power for a convergent cylindrical wave is proposed based on the self-reciprocity method, which turns the acoustic-power measurement to an electrical-parameters measurement. The formula for estimating the acoustic power was derived for a cylindrical concave transducer. The diffraction and the reflection corrections were also investigated for the precise measurement of the acoustic power. The performance of this method was compared with that of the radiation force balance (RFB) method. The experimental results showed good agreement. Moreover, the self-reciprocity method is more robust to the environment than the traditional RFB method and in practice can be extended to low-level acoustic power measurements.
