Structural vibrations couple with interior and exterior acoustic fields to produce sound. A vibrating structure generates sound waves in an acoustic field, and conversely, the acoustic pressure affects the structural vibration, along with stresses that may degrade structural integrity. Structural and acoustic regions may be assembled to capture waveforms and their interactions, while various boundary conditions and forcing functions are generally applied. This chapter first gives an overview of the traditional finite element (FE), boundary element (BE), and statistical energy analysis (SEA) vibroacoustic methods. This is followed by an overview of the alternative newer methods, hybrid FE/SEA, hybrid transfer path analysis (TPA), energy FE analysis (EFEA), and wave-based structural modeling, that have been developed. The modeling, computational, and application considerations for choosing the different methods are then described, followed by an outline of the book organization.
