Phantom Noise

Or pulse synchronous tinnitus (a whooshing thump that is the sound of your own heartbeat). This can be quieted down sometimes by pressing on the jugular vein for a few seconds. Do this several times, if it continues after that, put on a heavy metal album and shadow dance the night away - you won't be getting any sleep that night pal! Ha ha - heee. e

Or you can get Intracranial noise. This is the weird crackle and pop of the hollows in your head gurgling full and empty as the pressure rises and falls. You kind of feel/hear these noises - it is very odd.
