AB -  The  boundary  element  method  (BEM)  is  sufficient  for  calculating  Transmission  Loss  in  the 
acoustics  silencer  systems.  BEM  will  be  implemented  by  either  the  conventional  four-pole  transfer  matrix 
method or the recently developed three-point method, but there are some short for each method. The three-
point method is easier to use, and faster than four-pole methods. It does not produce the 4-pole parameters, 
the section being evaluated cannot be inter-linked with other sections. In order to perform such an evaluation, 
in this study, an improved method based on the four-pole parameters for use in the BEM is presented. The 
major advantage of the improved method is that it not only provides a very fast method for computing the TL, 
but it also produces the four-pole parameters.
