Considering limited available information on uncertainties in structural-acoustic coupled
systems, two methods namely the vertex method and the Legendre orthogonal polynomial …

Statistical modal energy distribution analysis (SmEdA) extends classical statistical energy
analysis (SEA) to the mid frequency range by establishing power balance equations …

An automatic methodology for identifying SEA (statistical energy analysis) subsystems within
a vibroacoustic system is presented. It consists in dividing the system into cells and grouping …

The vibration transmission path systems are generally composed of the vibration source, the
vibration transfer path and the vibration receiving structure. The transfer path is the medium …

When solving a vibroacoustic problem in a physical system, a fundamental goal is to
determine how energy is transmitted from a given source to any part of the system. This …

Finding the contributions of transmission paths in statistical energy analysis (SEA) models
has become an established valuable tool to detect and remedy vibro-acoustic problems …

Statistical energy methods in vibroacoustics, like the statistical energy analysis (SEA) or the
statistical modal energy distribution analysis (SmEdA), rely on specific modal coupling …

A description of coupled structures, and structures with blocked degrees of freedom, is
presented in terms of direct transmissibility functions (DTFs) as an alternative to the standard …

This article presents a new idea by applying different sound package parameters of to
improve the acoustic performance of the commercial vehicle cab. A statistical energy …

In this work, we explore under which conditions transmission path analysis (TPA) developed
for statistical energy analysis (SEA) can be applied to the less restrictive energy distribution …
