Tinnitus & Hyperacusis
Center, University of Maryland at Baltimore
"...Tinnitus Retraining Therapy (TRT), uses a combination of low
level, broad-band noise and counseling to achieve the habituation of
tinnitus, that is the patient is no longer aware of their tinnitus,
except when they focus their attention on it, and even then tinnitus
is not annoying or bothersome."
