Tinnitus: Temporary Relief

There are only a few times where I have experienced an absolute silencing of the ringing. I am a volunteer scuba diver at the Monterey Bay Aquarium. Every other Monday I drop into the Kelp Forest and perform a feeding show. During the show and for two hours afterward I experience absolutely no ringing. It is incredible. Then after about two hours it is like a lightswitch that flicks on and the ringing starts again. I would like to see someone research the effects of placing tinnitus sufferers into a hyperbaric chamber for temporary relief.
