Just as you will hear the sea if you put a shell to your ear, in a cup held to your ear you will here the tea.
(Actually the other answerer is correct, it is not a well-understood phenomenom. Suffice to say that "sound" is just your brain's interpretation of the movement of tiny hair-like structures inside your inner ear, closing the 'outer ear' from the eardrum to the cup seems to create a sort of "pre-amp" that is further amplified by your regular inner ear, so you "hear" all those gas molecules rushing about!)

Probably your own pulse, or the sound of your own breathing.
