This paper briefly describes experimertal results of propeller cavitation noise in uniform dilute solution of polymers. The motion equation of spherical bubble is derived by means of Oldroyed's constitutive equation which is applied to uniform dilute solution of polymers. The dimentionless parameters controlling noise radiation of spherical bubbles in the solution of polymers are obtained. These parameters are (1) bubble Reynolds number Re, (2) elastic paramerter of solution T~*, and (3) concentration parameter of solution c'[η].The effect of these parameters on noise radiation of spherical bubble is qualitatively discussed as well. The experimental results of propeller cavitation noise are explained by this spherical bubble theory. Limitation of this theory and further research proposals for this subject are also discused.
