Simulate the transmission loss of a muffler

I want to use the acoustic capability of code aster to obtain the transmission loss of an automotive muffler.
For the mechanical analysis, there are a lot of tutorial and example, but I found nothing for acustic.
Then, I don't know how to start. Anyone can help me?

Thank you

Hi

Perhaps here is a good place to start?  (cannot post links)
Index» Code_Aster usage» Acoustics - Internal Wall/Hard Boundary

You can use CA to calculate TL but only without Mach compensation.

TL keeps popping up for acoustics. It is good to search the forum on Acoustics.
