A sound wave can be cancelled by being exposed
to a reciprocal wave (180° opposite) of the same pitch and volume.

Using this law of physics, Columbia and Bell Labs scientists, Drs. Daniel Choy and Ivan Kaminow, created, in 2000, a successful treatment for tinnitus (ringing-in-the-ears) which, according to the American Tinnitus Association, affects over 50 million Americans and some 250 million people worldwide.

The treatment, known as the Padden-Choy procedure, was granted FDA approval in 2003 and is now in use in the U.S., Europe and Asia. The procedure is being made available via apps developed for Apple and Google mobile platforms that will enable tinnitus sufferers to self-treat essentially anytime, anywhere.

Using the new app, called “Phase-Out,” a patient determines the pitch (frequency) and volume (loudness) of his/her tinnitus. This wave is shifted out of phase by the app by six degrees or 30 sec., sequentially, and sent into the brain via earphones for 30 minutes (360°).

It can be proven mathematically that a patient’s tinnitus wave is cancelled one-third of the time.

From 2000 to 2007, with a three decibel reduction (50% on a linear scale) as the success level and a treatment schedule of once a week, for three weeks, the success rate for the procedure world-wide was 61% with an average fall of 8.5 decibels.

From 2007 to 2010, with the treatment schedule compressed to three times per week, the success rate increased to 81%, with an average fall of 7.6 decibels.

In 2011, when the treatment schedule was further compressed to three consecutive days, 67 of 67 patients dropped their volumes by 8.4 decibels (86% on the linear scale). At this level, no tinnitus is audible.

We are not claiming 100% success because there is no 100% success in medical research. Patient number 68 may fail, but this is unlikely.

These data have been published in the peer reviewed literature and presentations have been made to every international symposium on tinnitus since 2004.
