| Abstract: | In this paper, the radiating sound powers of two stiffened cylindrical shells are determined in an underwater semi-reverberant environment. The measurement method is verified by similarity relation of underwater acoustic radiation, which shows that the difference in the measured results is about l-2dB at the higher frequency range. |
