Sound Radiation by a Disc in Acoustically Rigid Baffle

Pavel Lukyanov

Abstract

A solution of the problem on sound radiation by a disk in an infinite plane baffle is given. Radiation impedance for arbitrary radial velocity distribution is obtained using the Fourier series and integral approach. Various cases of boundary conditions for the disk's edge in the baffle are considered. The obtained solution is compared with well-known ones by Rayleigh, Bouwkamp, Pritchard and Porter.
