ÂTinnitus, a condition of ringing or buzzing in the ears, afflicts over 40 million Americans, and millions more people worldwide. A quarter of these people are severely debilitated,Â said Dr. Dennis Woo (PhD), Vice President of Spectral Visualization and Development (SVD) Inc. SVD is a software company in Canada that has developed a revolutionary new product, called Quiescence, for diagnosing and treating tinnitus.
ÂQuiescence allows audiologists to precisely model the patientÂs tinnitus,Â said Dr. Woo, Âand reproduce a sound that exactly matches the tinnitus pitch of the patient. When this sound is played to the patient, the majority of tinnitus patients will experience a silencing of the tinnitus known as residual inhibition. This sound is recorded into an audio CD or other popular format such as MP3 players that patients can use to relieve the tinnitus as needed.Â
ÂThis is a nice means of getting patients to participate in their own treatment,Â said Dr. Tom Robertson from the Beltone Hearing Clinic in Springfield, Illinois. ÂItÂs non-invasive, and allows patients to lead more normal lives.Â
A recent study undertaken by the School of Human Communications Disorders at Dalhousie University in Nova Scotia used Quiescence to examine the effectiveness of frequency matched masking and residual inhibition in tinnitus therapy.
ÂThe results confirmed our assumptions that residual inhibition is an effective means of treating tinnitus,Â said Dr. Woo, Âand that Quiescence is an effective tool for targeting a patientÂs specific tinnitus sound and quickly creating an exactly matched tone that will bring relief.Â
ÂMatching the tinnitus pitch and frequency does a much better job of producing residual inhibition than when it is not matched,Â said Dr. Jack Vernon, Professor Emeritus of Otolaryngology at the Oregon Health & Science University. Dr. Vernon is commonly acknowledged as the Âfather of modern tinnitus masking.Â.
ÂFrom the findings of this study,Â said Dr. Vernon, Âit looks like Quiescence does this successfully.Â
Dr. Ravi Sockalingham of Dalhousie University supervised the study. ÂThe software itself is easy to use,Â he said. ÂEverything is software-driven. You just point and click at features that are well laid out.Â
ÂThere are many other tools for tinnitus,Â said Dr. Woo, ÂBut Quiescence is unique because it actually finds out where the tinnitus is located. Other tools basically just cover up the tinnitus no matter where it is, a sort of one-size-fits-all approach. Quiescence allows audiologists to make a CD that is customized for the patientÂs specific tinnitus.Â
ÂQuiescence is also very affordable and convenient,Â said Dr. Woo. ÂAudiologists will simply purchase their licenses and use Quiescence on as many patients as they want at no additional charge. And all the patients need is a CD player that they can use at home or even while driving. Plus, the tinnitus parameters obtained by Quiescence can be incorporated into devices such as hearing aids to increase the level of tinnitus relief.Â
