The overall aim of this research is to establish an effective method for accurately estimating the noise power radiating from gear blanks. For this purpose, the basic theory for estimating the frequency response of radiated sound power was proposed in previous papers, and was applied to a circular plate with a solid shaft subjected to an axial load, in which the circular plate was a simple model of gear blanks. The basic theory was extended in previous papers to the circular plates excited three-dimensionally similar to that for helical gears. In this paper the basic theory has been further extended to include the rigid-body modes of vibration as well as the natural modes of flexural vibration of the circular plates. Consequently, the estimation of radiated sound power was much improved in a low-frequency range below 3 kHz, where the rigid-body modes existed.
