Tooth mesh frequency sound generated aerodynamically in the region of meshing was investigated to determine the general characteristics of the sound emission as well as its detailed source locations. Sound pressure response measurement for various facewidths revealed that emission is expressed in terms of a similarity law as a function of a parameter b/λ, the ratio of facewidth to wavelength of the sound. The effect of dimensions such as the module and number of teeth were derived by means of a dimensional analysis with respect to pumping action of the cavity between driving and driven gears. Throughout several kinds of experiments, one source was located at the middle of the meshing exit, which becomes prominent as the axial air flow reaches a certain speed. Another source is estimated to spread over both faceends, of which the radiation characteristics are closely related to the distribution and the solid boundary of the gear pair.
