THE MUTUAL RADIATION IMPEDANCE OF CIRCULAR RINGS ON OBLATE SPHEROIDAL BAFFLES

Abstract

A pulsating circular ring of short axial length radiating sound from its exterior surface is idealized to be equivalent to an equatorial zone in a flat oblate spheroidal baffle. The velocity potential of such a zone is studied in detail. Two such zonal radiators are fixed upon a common axis coinciding with the axis of revolution. Formulas for the mutual radiation impedance coefficient between these rings in the absence of scattering are derived and discussions upon them are made. Numerical calculations are however not included because of the complexity of the derived equations. (Author)
