Vibroacoustic Analysis of a Rectangular Enclosure Bounded by a Flexible Panel with Clamped Boundary Condition
Figure 10
(a) Ratio between the panel vibration energy and sound field energy for two acoustical modes: (0,0,1) enclosure-controlled mode and (3,1) panel-controlled mode. (b) Resonance frequencies of two acoustical modes, the (0,0,1) uncoupled enclosure mode, and the (3,1) panel mode. (c) 60 dB modal decay time . (d) Resonance frequencies of two acoustical modes with different truncation numbers. m, s, s.
