How Can Some People Hear Their Own Eyeballs Move?

A disorder of the inner ear called superior canal dehiscence syndrome causes every sound within the body to be amplified, even the movement of one’s eyeballs, all the time. Sounds strange, but it is true (and treatable) … Believe It or Not!

It sounds like something out of an Edgar Allen Poe tale of horror. A man becomes agitated by strange sounds only to find that they are emanating from inside his own body—his heart, his pulse, the very movement of his eyes in their sockets.

Such a breach results in distortion of hearing and, often, impaired balance.
