This paper proposes a method to estimate the radiational sound field from circular pipe structures which have vibration surface. Laplace transform and the Wiener-Hopf technique are used to analyze the sound propagation and radiation. After this analytical formulation, a computer simulation algorithm has been derived as a form of matrix equations. Experimental investigation has also been performed using model acoustic tubes to verify analytical results. Sufficient agreement has been found between the numerical calculation and the measured response, and this concludes that the method proposed here can be practically applied to estimate the acoustic behavior of some machine components, as mentioned above.
