A while back I read a meterology text book to learn about the atmosphere and on one of the pages there was a factoid about the human jaw resonating at an infrasonic frequency between .4-.8 mhz. I think it can be heard when you clench your jaw and release it. I believe this is relevant because most of information about infrasound I find talks about how it can cause anxiety and other phsyiological changes in the body, but finding the information about the jaw is difficult. Links would be awesome. I recieved an infraction from an admin. because I asked a question about this factoid and would like to know if it can be verified.
