[EN] The main objective of this Thesis is the development, design and implementation of an experimental test rig to obtain the acoustic characterization of mufflers and other elements of the exhaust line of internal combustion engines in the presence of mean flow. It has also been carried out a review of the models typically found in the literature for characterizing absorbent materials and perforated surfaces. Next, it has been studied the different indices representing the acoustic response of mufflers, and has been selected as most suitable index the transmission loss. First, a theoretical study of the governing equations of the acoustic phenomenon in ducts in the presence of mean flow has been carried out. Also, a review of the typical ...
