The Brain: "Ringing in the Ears" Actually Goes Much Deeper Than ThatResearch on tinnitus has shown that it's rooted in the very way we process and understand sound. Today tinnitus continues to resist medicine’s best efforts, despite being one of the more common medical disorders.
When Schlee compared people who suffer a lot of distress from tinnitus with those who are not much bothered by it, he found that the more distress people felt, the stronger the flow of signals out of the front and back of the brain and into the temporal cortex. Such complexity may explain why so many different tinnitus treatments work, but only modestly: Each attacks just one part of the tinnitus network. Clearly the auditory cortex is just an early stop on the journey that sound takes from the outside world to our awareness. Steven Cheung and Paul Larson, two doctors at the University of California, San Francisco, set out to reproduce Lowry’s experience. Once signals travel from the ear to the auditory cortex, caudate, and putamen, they eventually make their way to regions of the brain that carry out more sophisticated sound information processing: connecting the sounds with memories, interpreting their meaning, giving them emotional significance. There are many reports of teenagers going to discos listening to loud music, and afterwards later in life experiencing this annoying ringing.
In bed, however, it gets louder, and when they are under a lot of stress, it gets too loud. Vibratory tinnitus is caused by mechanical sounds created by muscle contractions near the ear, changes in the ear canal, or blood flow problems involving the face or neck. If you are hearing persistent buzzing, clicking, ringing, or tapping noises inside your ear, you are just one in over 40 million Americans who is experiencing this disturbing sensation.

Some were convinced it was caused by wind that got trapped inside the ear and swirled around endlessly, so they tried to liberate the wind by drilling a hole into the bones around the ear or using a silver tube to suck air out of the ear canal.
Surveys show that between 5 and 15 percent of people say they have heard some kind of phantom noise for six months or more; some 1 to 3 percent say tinnitus lowers their quality of life. The vibrations cause nerve hairs in the inner ear to shiver, and that triggers electric signals that travel along the auditory nerve into the brain.
Things may start to go awry when toxic drugs, loud noises, or even whiplash cause damage to the nerve hairs in the ears. Christo Pantev of the University of Münster in Germany and his colleagues, for example, have brought some relief to people with tinnitus by rewiring their tone map. Some neurons in the auditory cortex extend branches down to the brain stem, where they link to a pair of regions called the caudate nucleus and putamen.
The experience left him with partial hearing loss and a high-pitched ringing in his ears that plagued him for 40 years. It is precisely these regions that Schlee and his colleagues noted were behaving strangely in people with tinnitus.
Traffic, iPods, and other features of modern life may cause more hearing damage, hence more tinnitus.
This sound of tinnitus varies from person to person, and may include hissing, roaring, whistling, pulsating, chirping or clicking.
If this happens to you, you will be able to hear sounds such as your own pulse or the contractions of your muscles.Non-vibratory tinnitus is caused by problems in the central or peripheral nerves involved with hearing. First, limit or avoid exposure to loud noises, such as music, power tools, gunshots, and industrial machinery.
To have appropriate home treatment, limit your use of aspirin, products containing aspirin, and other non-steroidal anti-inflammatory drugs, such as ibuprofen or naproxen. Tinnitus often localizes to one ear, with hearing-loss that becomes worse within 24 hours after an ear injury, or does not improve within 1 week of an ear injury. Tinnitus can force people to withdraw from their social life, make them depressed, and give them insomnia. Some have people listen to certain sounds, others apply magnetic pulses to the brain and even implant electrodes in the brain stem. They also signal back down the line, reaching out to neighboring neurons tuned to nearby frequencies, exciting some and muzzling others.


Winfried Schlee of the University of Konstanz in Germany and his colleagues have been making some of the most detailed studies of tinnitus ever, using a method called magnetoencephalography (MEG, for short).
Tinnitus, in other words, extends beyond the ear, beyond a hearing-specialized part of the brain, beyond even any single piece of neural real estate. To do so, they edited recordings of music, filtering out the frequencies of the ringing in the ears of their patients, who then listened to the filtered music an average of 12 hours per week.
Those regions may be important for processing the signals in several ways, such as categorizing sounds.
He argues that it is only when signals reach this large-scale network that we become conscious of sounds, and it is only at this stage that tinnitus starts to cause people real torment. Some find the sound intolerable and very difficult to live with, while others hardly notice it. In this case, you may hear sounds in one or both ears.Sometimes this type of tinnitus is described as coming from inside the head. If you cannot avoid loud noises, wear protective earplugs or earmuffs, but do not use wadded-up tissue or cotton balls. As you already know, you should try to quit alcohol and nicotine, and try to exercise regularly.
Each nerve hair is tuned to a particular frequency of sound and excites only certain neurons in the auditory cortex.
These feedback controls allow us to sift through incoming sounds for the most important information, so that we are not overwhelmed by meaningless noise.
Pantev and his collaborators found that their patients’ tinnitus significantly eased.
In 2004 Louis Lowry, an ear-nose-and-throat doctor at Thomas Jefferson University in Philadelphia, discovered that the caudate and the putamen play an important role in tinnitus by studying an unusual patient—himself. Cheung and Larson engaged five patients preparing to receive an implant who also suffered from tinnitus. Ear infections or eardrum rupture and dental or other problems affecting the mouth, such as temporomandibular (TM) problems could also cause tinnitus. These do not protect adequately against loud noises, especially the more dangerous high frequencies, and they may become lodged in the ear canal in some cases. Exercise improves blood flow to the structures of the ear, which can help stop the ringing in the ears. Although tinnitus does not have a cure, someone with the condition has coping methods and some cure solutions each patient should know. Recent research suggests why: Tinnitus is a lot more complicated than just a ringing in the ears.
MEG allows scientists to detect such changing patterns of activity in the brain 100 times per second.Schlee and his colleagues find widespread differences in the brains of people with tinnitus and those without it. Schlee’s model of tinnitus and consciousness could explain some curious observations. In some cases, injuries, such as whiplash or a direct blow to the ear or head is the cause. You must be careful when using stereo headphones; if the music is so loud that others can hear it clearly, or you cannot hear other sounds around you, the volume is too high. Maskers are small electronic devices that look like hearing aids and give immediate relief for tinnitus.
Cheung and Larson reported that the tinnitus became much fainter in four of the five patients. Even in bad cases of tinnitus, people can become unaware of the phantom sound if they are distracted. Injury to the inner ear following surgery or radiation therapy to the head or neck, a rapid change in environmental pressure, severe weight loss from malnutrition or excessive dieting and repeated exercise with the neck in a hyper-extended position (such as bicycle riding) could also be the cause of tinnitus you have experienced.
Try to cut back on or eliminate alcohol and beverages containing caffeine, stop smoking and using smokeless tobacco products. They make a sound to make the tinnitus less noticeable but you must know it does not cure or make the tinnitus go away.


The Roman writer Pliny the Elder suggested that earthworms boiled in goose grease be put in the ear. If a rat is trained to recognize sounds at a particular frequency, the corresponding region of the tone map will get bigger.
Schlee has determined that his tinnitus-stricken subjects have a more synchronized pattern of signals coming out of regions in the front and the back of the brain. Blood flow problems, such as carotid atherosclerosis, AV malformations, and high blood pressure and nerve problems, such as multiple sclerosis or migraine headache are also potential causes. Other diseases such as acoustic neuroma, anemia, labyrinthitis, Meniere’s disease, otosclerosis and thyroid disease can also cause tinnitus. It is good to exercise regularly, since exercise may prevent tinnitus by improving blood flow to the structures of the ear. Counseling, for example, can make people better aware of the sounds they experience by explaining the brain process that may underlie the disorder, so they can consciously reduce their distress. Ear or sinus infections could also lead to tinnitus, although this is often temporary and goes away after the infection is treated.
Maintain a healthy weight could help you stop ringing in the ears, because tinnitus occurs more frequently in obese adults. Play music or white noise when trying to fall asleep or anytime you find yourself in a quiet place and your tinnitus feels even worse. Because many people with tinnitus often have hearing loss, hearing aids make outside sounds louder, helping reduce the effects of tinnitus.
However, if tinnitus came with other symptoms, became persistent, or localized to one ear, you will need a visit to a health professional. You may consider buying a machine that makes soothing sounds, such as ocean waves to relieve these symptoms.
Often there is no cure for tinnitus, but your health professional can help you learn how to live with the problem and how to stop or at least relieve this ringing in the ears you have.
Vitamin B12 helps the body produce a substance that protects the nerves in the inner ear, and some think it protects against tinnitus. Anti-anxiety drugs, antidepressants such as nortriptyline, antihistamines and anticonvulsants can help some people against tinnitus. Good sources of vitamin B12 include milk and dairy products, meat, and eggs, so eat these foods to prevent your tinnitus.
It usually goes away, but for some people, that constant sound never goes away.Tinnitus particularly occurs in case of damage to the microscopic hair cells in the inner ear.
Tinnitus retraining therapy with TRT sound generators are worn in the ear and emit a quieter sound than maskers do. If you experience a loss of balance along with ringing in your ears for the first time, you should definitely think about seeing your doctor. TRT is relatively new and the overall effectiveness of the treatment is still up for debate and study, but your best bet is prevention. Hearing loss can actually worsen tinnitus, because without the ability to hear outside sounds, it becomes easier to hear the inner noise. A ruptured eardrum, earwax and an ear infection, which block outside sound, can also worsen tinnitus symptoms. Many people experience an occasional ringing, roaring, hissing, buzzing, or tinkling in their ears. The sound usually lasts only a few minutes but if it becomes persistent, you may have tinnitus. This condition called tinnitus is most common in people over age 40 and it affects men more often than women.
