Analytical and computational acoustic modelling of side outlet muffler and its extension in the modelling of tapered side outlet [PDF]
Archives of Acoustics, 2022 Mufflers are popular in the suppression of noise levels coming from various machinery. The most common parameters for the evaluation of the performance of mufflers are transmission loss, noise level, and insertion loss. The transmission loss is evaluated

Transmission Loss of Plasterboard Walls [PDF]
The Journal of the Acoustical Society of America, 1966 Although test data are available for many variations of the typical plasterboard wall, there are enough minor variations in construction or test technique that it is difficult to deduce accurately the effects of the various parameters. Accordingly, a systematic study has been made of a number of experimental and practical walls.

Transmission loss predictions for dissipative silencers of arbitrary cross section in the presence of mean flow [PDF]
, 2003 A numerical technique is developed for the analysis of dissipative silencers of arbitrary, but axially uniform, cross section. Mean gas flow is included in a central airway which is separated from a bulk reacting porous material by a concentric ...

Local model of plane acoustic waves propagation in multilayered infinite sandwich structures
Archives of Mechanics, 2011 A local model for computing the coincidence frequencies and the transmission loss of multilayered infinite sandwich plates composed of isotropic layers is presented in the paper. The model is derived within the local theory of linear elastodynamics under
