DOI: 10.1177/0954406218780894
Abstract: A modal impedance-based statistical energy analysis for point, line, and area connected complex structural-acoustic systems is introduced. The proposed methodology is applied to perform mid- and high-frequency vibro-acoustic analysis of a cabinet model. The cabinet… read more here.

DOI: 10.1177/0954406219843571
Abstract: The Statistical Energy Analysis (SEA) approach has largely been used in vibro-acoustic modelling to predict the averaged energy in coupled vibrating structures and acoustic cavities. The average is performed over an ensemble of nominally identical… read more here.
