Abstract Authors present a study on transmission loss and absorption of corrugated PVC panels. Tests were conducted in reverberation room and it has been proven, both theoretically and experimentally, that there is a relationship between the panel type and its transmission loss and absorption. Panel size and thickness was also taken into consideration during testing procedure. Analyses also show that the Hansen model was not perfectly accurate when predicting the transmission loss for some of the tested samples.
The primary goal of this research was to study transmission loss and absorption of fluted PVC panels using experimental and theoretical methods. During these studies, the link between panel size, thickness, transmission loss, and absorption was considered. We measured the transmission loss and absorption in reverberation rooms according to ISO standards. Hansen’s theoretical model was also used to predict the transmission loss. Agreement between TL prediction according to Hansen’s model and measured results for some of the studied panels were observed. However, the analytical prediction, according to Hansen’s model, for heavy fluted PVC panels must be used with caution. The absorption properties of the studied fluted PVC panels are also connected with their resonance, and, in addition, the resonance frequency is associated with the space between the ribs and wave propagation in the panel’s plane.
