- Opis:
- A computation method and the resultant formulas for the active sound power of axisymmetric free vibrations of a circular plate simply supported by a planar rigid baffle have been presented in the paper. Processes sinusoidally varying in time have been considered. It has been assumed that there are no reflexive influences of the air column over the plate and the baffle on the plate's vibrations. The integral formula for the active sound radiation in the Hankel's representation of null order has been transformed to a formula in an elementary form. This elementary formula contains the Bessel's and the Struve's functions of null and first orders and is valid for a relatively wide range of low frequencies.
