“…Due to space limitations, the one design that gives more TL with less volume will be the best design for the muffler. [5][6][7] For the analysis purpose single chamber and double chamber, reactive mufflers with pores and without pores are considered. Figure 2 shows double chamber muffler with pores.…”

“…They found that the proposed muffler is effective to reduce the both wide band noise and narrow band noise. Chao et al 6 have explained the application of parametric optimization techniques for acoustic performance analysis of the reactive mufflers. They found that by using the optimization technique, the Nelder Mead algorithm can minimize the pressure drop and maximize the TL with the given weight factor.…”

“…Orthogonal experimental design was initially used in conjunction with test experiments [10]. The results of early studies showed that the structural parameters of muffler units, such as the expansion and resonance cavities, significantly impacted acoustic performance [10]. The use of orthogonal analysis became widespread with the development of threedimensional numerical simulations.…”

“…Transmission loss and pressure drop predictions for exhaust mufflers have undergone significant improvement over the past decades [10]. The modeling uncertainty and sensitivity must be explained so that the potential benefits of unconventional configurations, which are outside of the range of empirical models, can be reliably assessed.…”

“…Much of the literature on the optimization techniques and sensitivity analysis in the acoustics of ducts and mufflers are deterministic methods for evaluation of the effects of different geometry configurations on the acoustic performance of the whole structure [10][11][12]. In these researches, the results of different modeling techniques for acoustic characteristics are compared for each geometry separately.…”
