The sound level from a car depends to a great extent of the quality of the muffler. Over the years, researchers in the car industry have struggled to produce mufflers that are efficient from both an acoustic and an environmental perspective.
This model describes the pressure wave propagation in a muffler for an internal combustion engine.
The model also shows how to analyze both inductive and resistive damping in pressure acoustics.
