Hi guys!
I have a model muffler of an exhaust that will to analysis. i will to measure Sound intensity(db)
& frequency of outlet. i show a picture of my muffler in this picture(I show inlet & outlet,too):

I have several question:
1- Which calculator should I use(which interfaces?(pressure acoustics(frequency domain(acpr)) or...))?
2- How to meshing?
My Assumptions is on inlet:
frequency range: 1000hz to 20000hz
Sound intensity range: 30db to 130db
Now, I will calculate sound intensity & frequency of outlet. I will to know that my muffler how Reduced the sound intensity & frequency of outlet.
How to do this job?
please help me!
