2.3 FEA model coupled with BEM
Sometimes a detailed analysis is preferred to get the acoustic modes and sound pressure values at any point
between the source and the receiver location. This requirement calls for building an acoustic cavity analysis, which
takes the vibration inputs from a FEA model [8]. The acoustic cavity model using CAE can also be used early in the
development cycle, the steps used for acoustic analysis is shown in Figure-3. However, unlike acoustic modal
testing, the CAE normal mode solution cannot scale the relative amplitudes of the modes. The sheer number of
acoustic modal frequencies to be avoided can be a serious deterrent during the early design phase. This work gives
