sorry for being off topic

offtopic schmofftopic- welcome fellow auditory freak-of-nature!

I tried your little experiment and didn't hear the sound through my mouth. It seems possible that it could have something to do with Eustachian tubes. The sinuses in the face and head also have astounding acoustical properties. (Another experiment to try at home kids! Open your mouth like your blowing a smoke ring and rap the very top of your head with your knuckles, HARD. Now try it again, but this time manipulate the sound by varying the size of the imaginary smoke ring!)
