Sound Insulation of Corrugated-Core Sandwich Panels With the extension of the applications of sandwich panels with corrugated core, sound insulation performance has been a great concern for acoustic comfort design in many industrial fields. This paper presents a numerical and experimental study on the vibro-acoustic optimization of a finite size sandwich panel with corrugated core for maximizing the sound transmission loss. The numerical model is established by using the wave-based method, which shows a great improvement in the comp... more

Sandwich panels typically consist of an upper and a lower painted metal skin and an insulating core made of rigid polyurethane foam. Before production, the skin layers are laminated with a protective film that must withstand all of the processing steps: from profiling and preheating, the application of the polyurethane core and its exothermic foaming reaction through to the cutting and stacking of the finished panels.
