Abstract

The purpose of this study is to identify parameters that affect the rate of sound transmission loss. Mathematical model of sound transmission loss (STL) is developed for laminated glass and maximize the STL of laminated glass by using response surface methodology (RSM). The main objective of this study is to determine the type of material and number of interlayers for laminated glass on the STL performance. The two-load transfer function method (TFM) coupled with LMS Test Lab Acoustic software to determine the STL. The analysis was made by observing the performance of STL with respect to different materials used, such as glass and Perspex. Besides that, number of interlayers for laminated glass also had been studied for the performance of STL. Next, the RSM will be applied to develop mathematical modelling of STL for laminated glass. Optimization on the variable of laminated glass also has been conducted to obtain optimum variable of laminated glass in order to deliver optimum STL performance.KeywordsLaminated glassSound Transmission Loss (STL)Response Surface Methodology (RSM)Mathematical modelling
