It is shown theoretically and experimentally that acoustic isolation or "noise reduction" (NR) of spacecraft structure can be computed and measured by conventional methods developed for rectangular box; some features of NR of axisymmetric spacecraft shells are then discussed and it is indicated how these calculations relate to LF (below 50 cps) noise reduction of rectangular box; finally, effect of double-wall sandwich construction of current space vehicle on its acoustical behavior is discussed.
