• The finite element method is applied to acoustic field around a cylindrical tank in order to analyze the diffraction effects. The method used in this study is the so-called hybrid-type infinite element method. The cylindrical tank situated in a finite domain perturbs the acoustic field radiated from a point source. The finite domain is divided into many finite elements, which are combined with the infinite elements on the inter-element boundary using an arbitrary interpolation function. The numerical result is compared with an experimental result which was obtained for acoustic field around a water tank of a thermal power plant. From these studies, it can be seen that the hybrid technique using the combined finite and infinite elements is useful for the analysis and prediction of noise around some obstacle like a water tank.
