ST7-1.40.130.5 Acoustic Cavity Modes with Flexible Boundaries
The acoustic cavity modes described in ST7-1.40.130.1 Calculating and Analysing Acoustic Cavity Modes are calculated under the assumption that the walls of the cavity are rigid. For a cavity with very thin walls, it is possible to get a strong interaction between the wall vibrations and the acoustic resonance inside the cavity. This Webnote presents the analysis of an acoustic cavity, which is coupled to a flexible wall.
