  Hi Cristiano, are you using APDL or Mechanical? There is an example in APDL on transmission loss of muffler that you can find at this linkfrom Acoustic user's guide. From your first image, looks like you just have one inlet and one outlet (on which we would place the port for TL evaluation), could you clarify the concern of two ducts? n
