@Article{JICS-2-61, author = {}, title = {Improved Method of the Four-Pole Parameters for Calculating Transmission Loss on Acoustics Silence}, journal = {Journal of Information and Computing Science}, year = {2024}, volume = {2}, number = {1}, pages = {61--65}, 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. }, issn = {1746-7659}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/jics/22821.html} }
