Abstract:
An analytical
model based on statistical energy analysis (SEA) is developed
for the sound pressure levels inside a box-like structure due to
wide-band random excitation applied at a prescribed point on the
structure. Some conditions that the sound field inside cavity
must adapts to SEA assumes are given. The sound responses inside
the box structure for four different input mobilities are
predicted using the SEA model and compared with experimental
results. On the basis of these results, possible ways of
reducing the noise inside the box structure are suggested.
