Tinnitus, or ringing in the ears, affects 32% of the general population. An effective treatment for tinnitus using destructive interference has been developed and proven effective.
A sound wave can be cancelled by meeting a reciprocal wave (180° opposite) of the same pitch and volume. Using this law of physics, Columbia and Bell Labs scientists, Dr. Daniel Choy and Ivan Kaminow, created a successful treatment for tinnitus, or ringing in the ears. It is in use in the U.S., Europe and Asia and is called the Padden-Choy procedure. The procedure uses a phase-shifted signal that fades away tinnitus symptoms.
A patient determines the pitch (frequency) and volume (loudness) of his/her tinnitus. This wave is sequentially shifted out of phase and played back through headphones for 30 minutes.
FDA approval was granted in July, 2003.

Same for an Apple version a buddy tried out for me on his iPod. Dr. Choy, you need a new programmer, someone with lots of experience writing for mobile devices.

Does not even open. You get fifteen minutes and after that you're stuck with it. Do not buy this app!
