碩士 / 國立臺灣大學 / 造船及海洋工程學研究所 / 85 / Experimental measurements of underwater sound attenuation and phase speed in a mixture of air bubbles in water were conducted. The bubble sizes in the mixtures were controlled to be about 1-mm to 3-mm in average diameter, and the source frequencies are from 700 Hz to 20 kHz. The measurements of attenuation and phase speed show good agreements with the theoretical values in the region investigated.
