Absorptive Muffler

Absorptive Muffler

The sound level from a car depends to a great extent of the quality of the muffler. Over the years, researchers in car industry have struggled to produce mufflers that are efficient in both acoustic and 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.
