✦ Synopsis

In several recent papers, Munt has solved the problem of the radiation of sound out of a jet pipe by the Wiener-Hopf technique. In this extension of his work explicit formulae are given for both the far field radiation and the sound reflected back up the pipe for an incident plane wave. These formulae, which are valid to second order in the ratio of duct diameter to wavelength, are shown to be in excellent agreement with Munt's exact numerical computations.
