The existing sandwich structure of the aircraft cabin demonstrates a good sound insulation
effect in medium and high frequency bands, but poor in the low frequency band. Therefore …

An analytical method is developed to study radiated sound power characteristics from an
infinite submerged periodically stiffened cylindrical shell excited by a radial cosine harmonic …

Cylindrical structures are used in various fields owing to their good mechanical properties.
At the same time, the requirements for their acoustic performances continue to increase in …

The large-eddy simulation (LES) with the dynamic Smagorinsky model is used to predict the
interior sound of an idealized vehicle cabin under the excitation of the wall pressures from …

In this paper, an accurate and efficient numerical method for sound transmission analysis is
presented. As an alternative to conventional numerical methods, such as the Finite Element …

This paper deals with the deduction of new homogenized models for the flexural wave in bi-
periodic beams. According to the homogenization theory, the long-wave assumption is used …
