Designer Mufflers

Mufflers are used to attenuate noise emitted by a combustion engine, for example, and should typically perform well in a specific frequency range. Attenuation is measured through transmission loss, which gives the damping in dB as a function of frequency.
The Absorptive Muffler Designer simulation app is used for studying and designing a simple resonant muffler with a porous lining. With the app, you can perform an analysis of both inductive and resistive damping in a muffler of your choosing.
The app enables you to study the results after changing the dimensions of the muffler, the ambient working conditions, and the material properties of the porous liner.
