Investigation of the efficiency of various reactive mufflers by noise reduction and transmission loss analyses

Transmission loss and noise reduction of reactive mufflers are determined by linear acoustic theory and unsteady flow field study, respectively. The effects of extending the inlet tube of the muffler, adding holes to the extension, and the number of holes on both transmission loss and noise reductio...
