Tinnitus Retraining Therapy
Tinnitus Retraining Therapy-Stops Your Tinnitus Forever
Tinnitus is a disorder in which the patient tends to take notice of sounds
which appear to be coming from the head. Contrasting ordinary sounds, these
sounds are not created by any external source. Neither is there in the least vibratory
cochlear movement which happens in case the sound is produced by various
It goes to saying that such a noise can upset the affected individual who may
possibly get agitated from his daily work which requires focus.
The restorative treatment which involves medications is not enough in
curing the problem . It might only curb the levels which will arise as an after
effect. Surgery furthermore does not prove to be the definitive cure for this
It was established that most of the people who faced this problem did not
allow the sounds affect them negatively. This surveillance was helpful in the
emergence of TRT or tinnitus retraining therapy
http://www.tinnituseardr.com/retraining-therapy This latest model has its roots
embedded in the neuro-physiological and psychological principles.
The foremost principle of this model is that the limbic system which controls
emotions and the autonomic nervous system, controls the body functions that are
associated to the tinnitus crisis. According to the TRT model it is the limbic and
the autonomic nervous system which verify level of annoyance caused by tinnitus.
When there is no positive or negative reaction to the tinnitus sounds, habituation or
filtering out of the needless sound takes place.
On the other hand, where the tinnitus noise is related with negative emotions
then people are likely to concentrate on that reverberation. This can be the
consequence of incorrect counseling in which the medical doctors will tell the
patients that the trouble may be due to a brain tumor. Or else they may discourage
the patients by saying disappointing things like tinnitus is untreatable. This may
bring to mind a negative response and can exacerbate the problem.
Most of the time, our brain does not disburse any attention to those sounds
which it considers to be of no implication. Such sounds sooner or later get filtered
out. Habituating or filtering out of the tinnitus sounds is the objective of the
tinnitus retraining therapy. This can be achieved by exercising the brain into
filtering out the tinnitus sounds.
The tinnitus retraining therapy comprises of a sound rehabilitation as well as
the greatly desired direct counseling and direction, all the way through the
The sound therapy aims at manipulating the surrounding sounds in such a
way that they be converted into less obvious. At times when there is silence, the
tinnitus sounds becomes quietly apparent and distressing. This problem is rectified
by the use of the following devices such as:
Noisy electric fans, ticking of the clocks, the rush of running water or tuning
the radio in connecting two stations facilitate in getting one’s mind off the tinnitus
Hearing aids can be of assistance in masking the tinnitus sounds if the
hearing failure is in the frequency range of the tinnitus.
Tinnitus masks generate external sounds reminiscent of the artificial white
noise or the pink noise. The pleasant external sound as a result created helps in
masking the tinnitus sound.
Cochlear implants grant the much required electrical stimulation to the
Beside with these aids, the patients are counseled cut the pessimism allied
with the tinnitus sounds. The patients are educated with reference to the auditory
system and the human brain along with their responsibility in tinnitus. The
initiative behind enlightening is that the recognized perils do not stir up a strong
reaction. Once the intention of training is fulfilled, then the TRT can be
TRT has proved to be one of the most efficient and harmless treatments for
tinnitus and has shown enormous outcome
Tinnitus Retraining Therapy was developed in the late 1980’s by Pawel
Jastreboff, Ph.D., Sc.D. whilst working at Yale University; Dr. Jastreboff
developed his model of tinnitus which postulates the participation of the limbic
(emotional) and autonomic nervous systems in the insight of tinnitus. His research
began with the enduring effort at that time to explain the acoustics of tinnitus.
The probability was that by describing the tinnitus unerringly in terms of
pitch and loudness, diverse categories would be recognized and definite treatments
could be applied to each type with expected outcomes. Instead of the expected
results, on the other hand, researchers establish something entirely unpredicted and
More or less 75% of all the people who experience tinnitus are not affected
as a result of it and they take care of tinnitus resembling any other sound to which
they can easily habituate. They hear it parallel to the way we hear the sound of the
refrigerator in our kitchen, of which we are not usually aware and when we do hear
the sound, it is not annoying.
The researchers establish there is no dissimilarity in the acoustical
distinctiveness of tinnitus amid those who are not disturbed by it and those who
have a medical condition from it.
This was a reflective discovery and led directly to Dr. Jastreboff’s
supposition of a further cause for the agony caused by tinnitus. The physiological
and psychological practicalities of his tinnitus model are these:
1. The processing of information occurs on several levels for each sensory
system, each level contributing to the final stage when a signal reaches the cortex.
2. The auditory system is closely connected with the part of the brain that
controls emotions (limbic system) and the automatic response of the body to
danger (autonomic nervous system).
3. Connections within the nervous system are continuously modified,
resulting in the enhancement of significant signals and a decrease of neuronal
response to irrelevant signals.
4. Sounds that are new, or associated with a negative experience, are treated
as significant, evoke an emotional response that triggers the body to “fight or
flight.” The repetition of these sounds results in enhancement of their perception
and in a resistance of the perception to be suppressed by other signals. The
repetition of signals not associated with positive or negative reinforcement results
in the disappearance of a response to their presence, i.e., in habituation.
To understand how tinnitus develops, it’s helpful to understand how sound is
processed in the auditory pathways. In the absence of noticeable sound levels there
is still a high level of neuronal activity in the auditory nerve and pathway, but this
activity is random. The nervous system filters out this activity and it is not
perceived as sound. When we are exposed to a measurable amount of sound the
activity within the auditory system increases and becomes more regular and
synchronized. This activity undergoes extensive processing in several subcortical
centers within the auditory pathways before reaching the cortex where perception
of sound occurs.
This processing of information results in continuous changes of the
connections within the brain that are involved in transmitting signals from the ear
to the cortex. Repeated activations by a sound not associated with anything of
significance will result in decreased activation of the cortical and limbic areas. On
the other hand, sound associated with a significant event, particularly related to
danger, will be enhanced and will strongly activate the cortical areas and emotional
response. Our brain sorts sounds according to their significance, giving important
sounds high priority and filtering out, or habituating, insignificant sounds. The
rules controlling sorting priorities are in flux and change throughout an
individual’s lifetime. TRT postulates that with the proper training one can enhance
their perception of some sounds while training their brain to filter out other sounds.
This is the basis of TRT, training the brain to habituate tinnitus sounds and
classifying them to represent a neutral, insignificant signal. To achieve this it is
necessary to fulfill two basic conditions:
1. Removal of the negative association attached to tinnitus perception.
2. Preservation of tinnitus detection, but not necessarily perception, during
Signals that induce fear or indicate danger cannot and should not be
habituated. We must not habituate sounds that provide warning signals. The
decreased negative association of tinnitus is achieved through directive counseling.
The patient is taught the basic function of the auditory system and the brain
relative to tinnitus. Decreasing the reaction of the autonomic nervous system is a
primary goal of the therapy.
The second condition is less obvious but equally important. In order to
retrain the neuronal networks, it is imperative that tinnitus be detected. Retraining
cannot be achieved for a signal that is masked or undetectable. Thus, for
habituation oriented therapy, masking of tinnitus is counterproductive.
Low level, broad band sound is used to facilitate tinnitus habituation. Silence
actually enhances tinnitus and patients undergoing TRT are advised to avoid
silence. They should immerse themselves in a low level, emotionally neutral sound
environment. TRT involves use of in-the-ear sound generators to provide this
neutral sound environment. The sound generators are operated at a low enough
level that the tinnitus can still be detected. Broad band sound contains all
frequencies which gently stimulate the nerve cells in the subconscious networks
allowing them to be more easily reprogrammed or habituated, to no longer notice
The sound generators are worn continuously and can be taken out for sleep
or left in. The cost of the generators is about $2,200.00 to $2,600.00. The cost of
directive counseling is added to this. Therapy typically lasts for 12 to 24 months.
It is nearly impossible to conduct a double-blind, placebo controlled study
on TRT. It’s difficult to imagine how to construct a placebo that would seem like
TRT but be totally ineffective. Because of this there is no wealth of clinical
evidence as to its efficacy. Dr. Jastreboff claims that he has treated about 1,000
patients in his clinic at Emory University in Atlanta, GA and that 80% of these
have experienced significant improvement. Dr. Jastreboff however does not define
or qualify the term “significant improvement.”
