Influence of perforation and sound-absorbing material filling on acoustic attenuation performance of three-pass perforated mufflers
The finite element method is employed to calculate the transmission loss of three-pass perforated reactive and hybrid mufflers. The effects of perforated tubes and bulkheads on the transmission loss of three-pass reactive mufflers are investigated numerically. Two types of hybrid mufflers are consid...
