How long does it take to get a Hearing?

I finally got my decicision after waitng a year and of course it was denied for PTSD from MST. I asked a hearing, so now how long does that take before I am noifitied of whne and where that will take place. I have new evidence to submit. It's an assessment from two of the Dr's I saw while my claim was being decided. The assessment was never included. with the other evidence. This assessment says that my word of being assaulted can be taken as true due to my condition, even though I never reported the assault, even in other couseling and hospitailizations. It also says that it is more likely then not that MST is the cause of my depression and other issues. Is this going to help me or not?
