Abstract
Methods to predict a fairing's vibration level and interior sound pressure level were examined for the case in which the sound environment around the spacecraft is a progressive plane wave field. The following results were obtained: 1) The fairing's exterior sound pressure level can be predicted by using the analytical method for the infinite column of received progressive inclined plane wave. 2) The fairing's vibration level and the interior sound pressure level can be predicted with fairly good accuracy by the finite element method for the low-frequency range and by acoustic statistical energy analysis which considers the energy flow between exterior and interior acoustic field for the high-frequency range. In this case, the locality of the exterior acoustic pressure level should be considered.
