Abstract Honeycomb structures have recently, replaced with conventional homogeneous materials. Given the fact that sandwich panels containing a honeycomb
core are able to adjust geometric parameters, including internal angles, they are
suitable for acoustic control applications. The main objective of this study was
to obtain a transmission loss curve in a specific honeycomb frequency range along
with same overall dimensions and weight. In this study, a finite element model
(FEM) in ABAQUS software was used to simulate honeycomb panels, evaluate
resonant frequencies, and for acoustic analysis. This model was used to obtain
acoustic pressure and then to calculate the sound transmission… More >
