Tinnitus and Harmonic Therapy

Ringing in the ears According to Tinnitus treatment expert, Tinnitus is the perception of sound in the absence of any real sound.  These sounds are heard as periodic or constant noises. Ringing in the ears type noises are usually described as ringing, hissing, humming, buzzing, roaring, chirping or whistling. Tinnitus may be the result of hearing loss, sounds produced by adjacent structures, or other disease processes. While tinnitus has traditionally been thought to be produced in the ear, research has shown that tinnitus is produced by electrical activity in the brain (see the figure below or to the right).

To understand why this happens, we first have to explain how hearing works says tinnitus treatment specialist. See the figure below for the anatomy.

  1. Sound, which is transmitted as sound waves (vibration of the air), enters the ear canal and reaches the eardrum.
  2. The sound waves lead to the vibration of the eardrum, which also vibrates the small bones behind the ear drum.
  3. The vibration motion of the bones makes the fluid in the inner ear or cochlea to vibrate.
  4. The vibration waves in the inner ear fluid causes the sensory (hair) cells in the inner ear (cochlea) to bend. The hair cells change the movement into electrical signals.
  5. These electrical signals are transmitted through the hearing (auditory) nerve and up to the hearing part of the brain (auditory cortex), where they are interpreted.

In this way, the pitch (frequency) of a sound is translated to a physical space located in the inner ear.  For this reason, we say that the cochlea is “tono-topically” organized, meaning that each spot in the inner ear picks up a certain pitch of sound say tinnitus treatment specialist. If you were to take the inner ear membrane and flatten it out, it would be organized exactly like the keyboard of a piano.  This organization is maintained from the inner ear all the way up to the brain.

Tinnitus occurs when there is damage to the inner ear.  Further, the “ringing” that we hear approximates to the region of the inner ear that is damaged.  If the area  of the inner ear that detects high pitch sounds is damaged (for example by loud noise exposure, aging, hereditary, or toxic reasons), we hear a high pitched “ringing”.  When the damage corresponds to lower pitches, we hear a “buzz” or a “hum”.   Interestingly, most people with tinnitus have a high pitch ringing because the area of the inner ear that detects high frequencies is closest to the middle ear, and is therefore more susceptible to damage from infection, noise damage, aging, and general wear and tear says Tinnitus therapy specialist.

There is one more important concept to understand about why tinnitus happens, and this one is the most counter-intuitive.  It has to do with how the brain interprets signals coming from the inner ear.  One would expect that when there is silence, the brain is not receiving signals from the inner ear.  This is actually not the case.  Instead, the brain receives a constant and steady source of information from all areas of the inner ear.  The way that the brain interprets sound is by picking up increases in this steady state of background activity in the hearing areas of the brain.

Neuromonics for Tinnitus Treatment

Neuromonics is a device that is dispensed by an audiologist or a doctor that uses music for tinnitus treatment. Because music routes through the hearing parts of the brain, there is the potential for music to mask tinnitus.  Perhaps more importantly, music also has clear associations with the emotional parts of the brain.  Even passive listening to pleasant music can stimulate the parts of the brain that are associated with pleasant emotional states.

The use of music as a masker had been proposed as early as the late 1980’s, and the successful applications of music therapy for tinnitus has been demonstrated by numerous institutes.  Newer more sophisticated approaches are using music signals to achieve neuroplastic changes in the brain in order to achieve tinnitus relief.  For instance, in the Neuromonics approach, the music signal is adjusted to conform to the hearing test of the tinnitus sufferer, such that the frequency profile of the music is amplified in regions of hearing loss and attenuated in regions of normal hearing.

In a study performed by the company, Davis and colleagues (2008) compared the effectiveness of a customized sound/music tinnitus retraining (Neuromonics Tinnitus Treatment) with counseling alone. Patients were divided into one of four groups: 1) Neuromonics device at high intensity for two hours per day, 2) Neuromonics device at a lower intensity, 3) tinnitus therapy with a broadband stimulator and counseling, or 4) counseling alone. Subjects were instructed to listen to the devices for two hours per day at the time of day when symptoms were most severe.

Tinnitus Reaction Questionnaire (TRQ) improved over the 12 months of the study for the Neuromonics group. TRQ scores were not significantly improved in the control groups. At the six-month follow-up, 86% of patients in the customized acoustic stimuli groups had met the definition of success based on 40% improvement in the TRQ scores. Normalized visual analogue scores for tinnitus severity, general relaxation, and loudness tolerance were improved relative to both baseline and control group’s scores at 12 months. Perceived benefits were also greater with the customized acoustic stimulus.

What’s The Latest Treatment to Cure Tinnitus?

Tinnitus Sound Treatment

Are you hearing a ringing sound even though there is no external source? This is the reason why the condition Tinnitus is known as “ringing in ears.”  A person may perceive a sound other than ringing and that kind of sound that a person hears is often dependent on the root cause of Tinnitus. Tinnitus sufferers may experience intermittent or constant noises in one ear or in both ears or even throughout their entire head. The noises can take many different forms and occur at different volumes. The volume of the tinnitus sounds has been described subjectively by sufferers as ranging from soft to extremely loud.  The most common types of sound described has been, ringing, buzzing, hissing, clicking or chirping.

Each tinnitus sufferer experiences different levels of ringing in their ears. The sound can be ignorable for others, but it can also get so loud that it interferes with your daily activities. In fact, reports show that an estimate of 12 million people in the United States have been severely affected by the loud ringing sound that they are not able to live normally. It can also interfere with your ability to concentrate and sleep well, and it can lead to depression, among others.

Finding a tinnitus treatment that will cure ringing ears is important. In order to find the right Tinnitus cure, you need to do your best to ascertain what is causing the ringing. For many, the traditional Tinnitus rehabilitation is administered, allowing you to undergo therapy while listening to your own favorite music. Tinnitus sound therapy experts have found that traditional white noise works by covering up all frequencies, but in reality is unnecessary.

If very particular frequencies are covered up, then patients can actually listen to music or other ambient sounds on the rest. It leaves patients with the enjoyable experience of being able to rehabilitate their brain’s production of the tinnitus sound by listening to their favorite music as they go about their day. Tinnitus sound therapy allows the tinnitus sufferer to mix the therapeutic sounds that reduce the tinnitus with music. These special sounds, that are mathematically calculated, work on the parts of the brain that reduce tinnitus. By having the ability to mix your own music, you have the flexibility to listen to music you enjoy, not those preselected by a company.

 

What Should I do if I have Tinnitus?

Tinnitus is a noise that originates within the ear rather than from the outside environment.  The sound may have been described variously as a “ringing” sound, “whistling” sound, “buzzing” sound, or other type of noise that seems to originate in the ear or head. In many cases it is not a serious problem or disease, but rather very bothersome for says Tinnitus treatment specialist.  Nearly 36 million Americans suffer from this disorder and in almost all cases only the patient can hear the noise.

In addition to the noises associated with tinnitus, certain other symptoms may accompany this condition. These include:

Dizziness

Pain in the ear

A sense of fullness in the ears

Headache

What causes tinnitus?

According Tinnitus relief expert, some tinnitus or head noise is normal. Tinnitus can arise in any of the following areas: the outer ear, the middle ear, the inner ear, or by abnormailities in the brain. If a person goes into a sound proof booth and normal outside noise is diminished, one becomes aware of these normal sounds. We are usually not aware of these normal body sounds, because outside noise masks them. Anything, such as wax or a foreign body in the external ear, that blocks these background sounds will cause us to be more aware of our own head sounds. Fluid, infection, or disease of the middle ear bones or ear drum can also cause tinnitus.

In order to understand what causes tinnitus, and eventually how to cure tinnitus, it’s important to understand how the ear works. The ear is a fairly complex organ that converts sound waves into brain signals by passing the waves through the ear canal, onto the ear drum and then through the ear bones into the cochlea (inner ear), a small shell like structure that picks up individual frequencies. The cochlea works by transmitting different frequencies from the point where it receives the frequency to the corresponding point in the brain. The brain and cochlea are arranged exactly alike, with the frequencies (pitches) that are next to each other on the cochlea being exactly next to each other in the brain as well.

Tinnitus is caused when a particular frequency range in the cochlea is damaged and no longer sends information to the brain. This may seem strange at first as tinnitus is caused by the brain NOT receiving signals rather than receiving too many. To explain this, we need to understand one more piece of the puzzle of hearing: what do you hear when you hear nothing? Your brain is actually hearing a steady state of sounds, however soft, at every frequency simultaneously. Your brain tells you that you hear sounds only when it detects a pattern in the consistent noise it’s receiving. So, when you stop receiving signals from a particular frequency, it can no longer detect any patterns so you will at first hear nothing at that frequency. If you don’t hear anything at a particular frequency at first, why do you eventually hear too much at that frequency?

Your brain is incredible and is very, very good at reusing space. For example, if you are blind your brain will often convert the areas traditionally used for image processing to instead process extra audio, smell, and taste sensations. In the case of tinnitus, your brain quickly recognizes that you no longer have a use for the space reserved for the frequencies that are damaged in your cochlea, so it reuses the space for other frequencies. The frequencies near the damaged frequencies are given extra processing power. So they become better at detecting patterns and also tend to spontaneously fire more often. Unfortunately, that means they detect sounds much more regularly than other frequencies are detected, prompting the brain to create ringing or tinnitus.

Traditional Treatments of Tinnitus

Tinnitus can be treated with Tinnitus hearing therapy. Since tinnitus doesn’t actually affect the damaged regions of the cochlea, but instead affects the areas directly around the damaged zones in the brain, we need to focus on those frequencies and how to affect their brain functioning. As we found out in the causes section, those frequencies are now overly active in detecting sounds. In the past, the thinking has been pretty simple: just play sounds on the affected frequency to allow the ear to detect an actual noise instead of a perceived noise says Tinnitus hearing therapy specialist.

That treatment works a little bit, but it has serious drawbacks because you are only temporarily moving the tinnitus from inside the brain back to the ear that is hearing the actual sound. You will still hear the high pitched frequency; it just isn’t being created by your newly overactive brain any longer, it actually exists.

Doctors have experimented with using “white noise” to create sounds on all frequencies rather than just the one frequency that is affected with quite a bit of success. This way the brain hears sounds equally across all frequencies, affecting all parts of the brain. The affected areas are part of the white noise, so they hear actual sounds and the random, spontaneous noise stops showing up as often. Also, if you are hearing a lot of random noise then painful tinnitus gets lost in the noise. This is good news for tinnitus sufferers because now they have a solution that can help them get better.
