134 ABSTRACT Investigating the characteristics
of sound propagation in several orthotropic
materials will be presented. The Transfer matrix
method (TMM) was applied to calculate the sound
transmission loss in several orthotropic plates
made of fiber reinforce plastics (FRP).
Traditionally, the TMM is applied in the
isotropic materials. However, here we present a
new technique of solving the FRP laminate (an
anisotropic material) by combining the wave
equation and the TMM. The results from the sound
transmission level (STL) of the FRP will also
presented.
