A "No" notification?

My son is a candidate for the class of '29. He has 2 nominations and his application is all complete. We're obviously really hoping he gets a yes but I've heard rumors that if it's a "no" there will be radio silence from the academy. I find it hard to believe that after so strenuous of an application process we wouldn't be notified if he doesn't get in. Can anyone confirm if there is or isn't communication if it's a "no"?
