DTIC ADA286731: Proceedings of the Second International Congress on Recent Developments in Air- and Structure-Borne Sound and Vibration (2nd) Held in Auburn University, Alabama on 4-6 March 1992. Volume 2

Topics covered in the Proceedings include Sound Intensity, Structural Intensity, Modal Analysis and Synthesis, Statistical Energy Analysis and Energy Methods, Passive and Active Damping, Boundary Element Methods, Diagnostics and Condition Monitoring, Material Characterization and Non-Destructive Evaluation, Active Noise and Vibration Control, Sound Radiation and Scattering, and Finite Element Analysis. In the last 30 years, improvements in computers have allowed rapid developments in both theoretical and experimental analysis of acoustics and vibration problems. Power flow in structures also now can be determined with the use of structural intensity measurements. Sound and vibration signals are being used increasingly to diagnose the condition of machinery and to detect faults or to determine the properties of materials through non-destructive evaluation. There is also increased knowledge in sound radiation and scattering; in particular advances have occurred in scattering theory and in numerical solution techniques.
