| Summary: | The energetic aspect of sound radiation by a~clamped
annular plate has been considered. The total sound power, active and reactive,
was computed using the impedance approach, which makes possible to correctly
design some acoustic systems. The plate was excited by the external pressure of
an axisymmetric and time-harmonic distribution on the plate's surface. The
Kelvin-Voigt theory of a~visco-elastic plate was employed. The results of
a~modal analysis of an annular plate's in-vacuo motion were used. |
