Abstract
Vibrations of a homogeneous and isotropic single elastic plate driven by a spherical sound wave and the sound transmission through it, are investigated theoretically by means of the classical thin plate theory. A plate of infinite extent and a finite circular plate, on the normal central axis of which a sound source is located, are studied. For the former, comparison between the effects of plane wave incidence and spherical one is made, and for the later, using the distance from the origin of the central axis to the sound source as a parameter, vibrating plate profiles and transmission characteristics are presented. As a result, it is found that the flexural wave is caused more easily and the sound is radiated from the plate more efficiently with decrease of the distance between the sound source and the plate, i. e. , with increase of the spherical influence of the incident wave.
