Summary = A new study undertaken at the School of Human Communications
Disorders at Dalhousie University used a new software product called
prove that a form of tinnitus treatment called residual inhibition is an effective means for offering relief to sufferers of this mostly
incurable condition. The study results were greeted with optimism
by leading tinnitus researchers, including leading tinnitus researcher
Dr. Jack Vernon of the Oregon Health & Science University.
Body = “Tinnitus, 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,”
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.
allows audiologists to precisely model the patient’s tinnitus,”
said Dr. Woo, “and 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.”
is a nice means of getting patients to participate in their own
treatment,” said Dr. Tom Robertson from the Beltone Hearing
Clinic in Springfield, Illinois. “It’s non-invasive,
and allows patients to lead more normal lives.”
A recent study
undertaken by the School of Human Communications Disorders at Dalhousie
University in Nova Scotia used Quiescence to examine the effectiveness
frequency matched masking and residual inhibition in tinnitus therapy.
confirmed our assumptions that residual inhibition is an effective
means of treating tinnitus,” said Dr. Woo, “and that
Quiescence is an effective tool for targeting a patient’s
specific tinnitus sound and quickly creating an exactly matched
tone that will bring relief.”
the tinnitus pitch and frequency does a much better job of producing
residual inhibition than when it is not matched,” said Dr.
Jack Vernon, Professor Emeritus of Otolaryngology at the Oregon
Health & Science University. Dr. Vernon is commonly acknowledged
as the “father of modern tinnitus masking.”.
the findings of this study,” said Dr. Vernon, “it looks
like Quiescence does this successfully.”
Dr. Ravi Sockalingham
of Dalhousie University supervised the study. “The software
itself is easy to use,” he said. “Everything is software-driven.
You just point and click at features that are well laid out.”
are many other tools for tinnitus,” said Dr. Woo, “But
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 patient’s specific tinnitus.”
is also very affordable and convenient,” said Dr. Woo. “Audiologists
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.”
