RÉSUMÉ

The problem of sound radiation of plates influenced by nonuniform random fields of pressure fluctuations is solved. A nonresonant sound radiation procedure is considered. The expressions for estimation of sound pressure and sound power spectral density emitted by the plate at its inertial behavior are obtained. The influence of exciting field parameters on the sound power emitted by the plate is analyzed.
