22 Nov 2017 Request (PDF) | Sound transmission l | Honeycomb sandwich panels used for commercial applications are typically stiff and lightweight. They are optimized for mechanical performance, but have poor acoustical performance. Transmission loss (TL) is one of the metrics used to assess the acoustical
This study combines Bloch-wave analysis and the finite element method to understand wave propagation and hence sound transmission in sandwich panels with a D. Palumboa and J.

30 Jan 2015 It is highly desirable for ship, railway, and aerospace industry. The reason is that honeycomb panel excels in strength and in its weight. However in terms of insulation, it is a little bit insuffi- cient to commonly use sandwich-panel. In this paper, Moor's theory is used to predict sound transmission loss (STL).
Light composite sandwich panels are increasingly used in automobiles, ships and aircraft, because of the advantages they offer of high strength-to-weight ratios. However, the acoustical properties of these light and stiff structures can be less desirable than those of equivalent metal panels. These undesirable properties can
transmission loss of the laminate composite structures. This approach was successfully employed for the acoustic design of curved sandwich composite panels with noise controi treatments [10, 11]. In the context of predictive SEA, a wave approach for curved sandwich panels was proposed by K. Heron [12]. The dispersion

14 Jun 2012 is used to predict the sound transmission loss of honeycomb panels. Honeycomb is an anisotropic material which when used as a core in a sandwich panel, results in a panel with anisotropic properties. In this thesis, honeycomb panels are treated as being or- thotropic and the wavenumbers are calculated
