Abstract
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.
