The exact solution for radiation from a cylindrical pipe obtained by using the Wiener}Hopf method has been available for over 50 years. Approximate solutions can be used to simplify the problem, and their accuracy compared with the exact solution. Firstly, the exact solution can be simpli"ed by usin

Some issues involved in establishing a numerical model for sound radiation from a straight duct are addressed in this paper. The main ingredient of the numerical method is solutions of linearized Euler equations using a high order compact scheme. Farfield directivity is estimated through an integral
