The paper deal with the basic problem connected with the free vibration of finite cylindrical steel shell immersed in water. At the first there is described the theoretical model of this problem by means of the Helmholtz equation with the von Neumann boundary condition on the radiated surface. Next the results of a numerical investigation are presented. The final results are the acoustic characteristics obtained in the sea. These ones were compared to the numerical results.
