Abstract
In a recent presentation an attempt was made to introduce basic concepts in the development of the elements of the statistical energy analysis (SEA). [G. Maidanik, J. Acoust. Soc. Am. Suppl. 1 79, 511 (1986)]. The analytical definitions and manipulations were exercised on a simple dynamic system so that they could not clutter unduly the conceptual understanding of SEA. Moreover, although SEA is devised to deal mostly with the dynamic behavior of interacting structural system, many of the basic concepts that underlie SEA can be explained and understood employing a single noninteracting dynamic system. The modal approach was used and the division of the energy stored in the dynamic system into a resonant and a nonresonant part was derived. The significance of this division was briefly discussed. This paper discusses more recent concepts such as the division of stored energy into a direct and a reverberant part.
