Sound Pressure Distributions and Radiation Impedance for Flexible Disks. Part III.

Abstract

In two previous memoranda, methods were described for calculating the sound pressure on circular flexural disks and obtaining their radiation impedance. Unfortunately, it was only feasible to obtain the sound pressure by means of an electronic computer, and the radiation impedance data had to be obtained by numerically integrating this computer data for the sound pressure. In this memorandum the double integrals needed to compute the radiation impedance are evaluated. Simple expressions are given for radiation impedance suitable for direct hand calculation. (Author)
