This volume is a record of the proceedings of the Symposium on Statistical Energy Analysis (SEA) held at the University of Southampton in July 1997 which was held under the auspices of the International Union of Theoretical and Applied Mechanic~. Theoretical SEA is form of modelling the vibrational and acoustical behaviour of complex mechanical systems which has undergone a long period of gestation before recent maturation into a widely used engineering design and analysis tool which is supported by a rapidly growing supply of commercial software. SEA also provides a framework for associated experimental measurement procedures, data analysis and interpretation. Under the guidance of the members of a distinguished International Scientific Committee, participants were individually invited from the broad spectrum of 'SEAfarers', including academics, consultants, industrial engineers, software developers and research students. The Symposium aimed to reflect the balance of world-wide activity in SEA, although some eminent members of the SEA community were, sadly, unable to attend. In particular, Professor Richard Lyon and Dr Gideon Maidanik, two of the principal originators of SEA, were sorely missed. This publication contains copies of all the papers presented to the Symposium together with a summary of the associated discussions which contains valuable comments upon the contents of the formal papers together with the views of participants on some fundamental issues which remain to be resolved.

Some perspectives on wave-mode duality in SEA.- Wavelength scale effects on energy propagation in structures.- On the validity domain of some high frequency energy models.- Some energy relations for mechanical systems.- The energetic mean mobility approach (EMMA).- Irregularity, damping and coupling strength in S.E.A..- An approach to the statistical energy analysis of strongly coupled systems.- The energy flow equation of continuum dynamics.- A note on conservative and non-conservative coupling.- Predictive SEA using line wave impedances.- Statistical energy analysis of beams which are line-connected to plates.- Vibrational energy flows between two plates forming an ‘L’-shape and joined by compliant and dissipative couplings.- SEA coupling factors for regular and irregular structures.- Prediction of structure borne sound of low modal density structure by using SEA.- Power-flow analysis of quasi-one-dimensional systems with distributed coupling.- The estimation of dynamic stress and strain in beams, plates and shells using strain-velocity relationships.- Statistical energy analysis of parametric resonance in structural members.- On the external input power into coupled structures.- Statistical energy analysis in view of stochastic modal analysis.- Input power modulation method.- An indicator of coupling strength between SEA subsystems.- On the calculation of confidence levels of the experimentally derived internal and coupling loss factors.- The practical implementation of SEA.- Application of statistical energy analysis (SEA) to the development of a light truck sound package.- Predicting noise transmission in a truck cabin using the statistical energy analysis approach.- Statistical energy analysis of fluid-filled pipes.- SEA for predicting the efficiency of noisereduction solutions applied to an air conditioner unit.- Statistical energy analysis of nonconservatively coupled systems and its applications to engineering.- Calculation of structure-borne sound and radiation from automotive silencers using SEA and FEM.- Sound transmission through buildings using SEA.- The relationship between transmission coefficient and coupling loss factor.- Short communication on SEA applied to ship structures.- Summary of discussions.
