When I was in High School I would hear the same thing, It sounded like a man and woman talking and I couldn't hear them but I could feel the
vibrations if that makes any sense. It was always about 11 or 12 at night, and the TV was on as my dad would watch it, but the sound definately did
not come from the TV. I haven't heard the noise though since then, so not sure what it was.
I also wanted to add, that my mom heard the same thing except she was actually in that room and she freaked out, she said the talking was coming from
the closet, She blamed the TV but her and my dad I don't think they believe in ghosts and are in denial that we have/had one.
