- 摘要：
- The acoustical reciprocity theorem can be used to solve the problem of vibroacoustic
coupling. However, the theorem can be used only on the presupposition that the scattered
sound 'eld of the elastic surface concerned is known. This is the key point and the most
di$cult point for many complicated surfaces, such as a multicavity structure. A new method,
covering-domain method, which transforms the calculation of scattered sound 'eld of an
arbitrary-shaped closed shell into that of a series of simply closed spherical shells, is applied
in this paper to calculate the scattered sound 'eld of a multicavity structure with elastic
surfaces. So the radiated sound pressure of an elastic multicavity structure excited by an
external force can be predicted by using the acoustical reciprocity theorem. It is veri'ed to be
correct by a corresponding test in this paper.
