Popis:	The acoustic radiation power of a thin annular plate, clamped with both its edges — internal and external — into a planar rigid and infinite baffle has been analyzed. Some processes sinusoidally varying in time have been considered. The acoustic radiation power integral formula has been transformed by introducing contour integral in a complex variable plane. An elementary form of the acoustic wave radiation formula, useful for computations for high frequencies, has been presented. The formula represents the acoustic power with the assumption that the annular plate vibrates with n-th axially-symmetric mode.
