In establishing an effective method for accurately estimating the frequency spectrum of noise power radiated from gears, a basic theory was proposed in previous papers using a circular plate with a solid shaft as a simple model of gear blanks. The basic theory was theoretically extended in another paper for the case in which the exciting force was applied in a spatial, three-dimensional direction, such as for helical gears. In this paper, the extended theory is applied to a circular plate which has a single helical tooth excited in its normal direction in order to verify that the extended theory is effective. The estimated sound power compared well with the value measured by the sound intensty method. Also, an interesting result is obtained; sound power radiated from a circular plate with a helical tooth is proportional to sin^2β, whereβ is the helix angle. In other words, the axial exciting force has large influence on the sound power radiated due to the flexural vibration of the circular plate.
