I find that when you hold a balloon of mylar or latex filled with air or helium in close proximity to many, not all, peoples ears they remark that they "feel" pressure,as if they were changing altitude. I have had the same experience but am unconvinced if the sensation is due to pressure or sound absorbtion. It is not the same as holding a shell to your ear, or holding a solid surface next to your ear. It is not obvious, or does not occur, with inflated plastic bags or air filled balls. It is most remarked upon when an inflated mylar type balloon is held approximately 5-15mm from the ear, with no obstruction such as hair. Thank you.
