How reflection is modeled in acoustic module?

Recently I am modeling a transmission and reflection problem using background pressure field+PMLs. I found that the scattered field (acpr.p_s) can only be visualized in background field. The value of acpr.p_s is the same as the total pressure filed (acpr.p_t) on all the other domains. My questions are:
- Is there a prefered practice on where to assign the background pressure field?
- Is the acpr.p_s still accouted during the calculation but not stored in all the other domains?
- Can pressure acoutics module capture multiple reflections in the domain? A simple case is a point source in the room, instead of being only one time reflection, in deed there will be multiple times of reflection.
- If it's capable of capturing this, is there a limit on how many times the software can capture?
