Tinnitus is the perception of an insistent, unpleasant ringing, buzzing or other consistent noise, located in or near the skull but without a definable external source.
Tinnitus is often perceived as a ringing or persistent high tone very close to or within the ear. Tinnitus is often regarded as a symptom of auditory conditions, such as damage to the tissues in the ear that control the perception of tones and frequencies. An increasing number of researchers argue that tinnitus is a disorder of the connections between the inner ear and certain areas of the brain.
Some scientists had developed a theory that tinnitus was associated with deficiencies in vitamin B12.
Chronic inflammation of the middle ear (otitis media) may also be associated with some cases of tinnitus. Tinnitus related to otitis media may be improved by surgery to correct damage caused by this inflammation.
One of the alternative therapies employs the use of white noise to counteract this problem.
It promotes habituation which is the process of filtering out the insignificant stimuli. Thus, we find that audio frequency or sound therapy can be a boon for the tinnitus sufferers who have to tolerate loud noises every now and then.
So, both myself and Cognitive Daily have highlighted the recent news story that high school students have hit upon a ringtone that teachers can’t hear. Many people who listened to the 14kHz sound reported not consciously hearing the sounds, but did perceive a ringing in their ear, or a small pain.
We hear because thousands of tiny hair cells in the cochlea vibrate when sound waves enter the ear canal (for more read this). If you observe where the low frequency vs high frequency region of the cochlea is (in the diagram above), you’ll notice that the high freq portion is near the oval window. As anecdotal evidence, I have personally observed more surviving hair cells in the apex vs the base when i intentially deafen animals.
2 – maybe not in your expertise but do you know if some people tried to build a mechanical ear? I am no longer bothered by TVs unless I am really close to them, when I get that ringing or pressure feeling.
Another interesting place to find a stratospheric tone is at the end of the last track of Sgt. Although its not directly related, I thought it would be worth mentioning here that TRPA1 cation channels present on the tip of stereocilia have been associated with mechanosensitive functions.
I would like to use information from your blog, including answers to questions of questions for a children’s book I am writing.
Retrospectacle has been a wonderful hobby and outlet for my writing for almost three years. It is not considered to be a condition in its own right, but a syndrome or symptom related to many forms of auditory damage or disorder. Age-related hearing impairments, or disorders of the circulatory system around the ear, may also be related to this complaint.

Some scientists conclude that tinnitus is in fact related to damage of the nervous tissue in or around the auditory cortex of the brain. A recent study including 100 patients with tinnitus found that 63 of these had low vitamin B12 levels. As the natural molecule histamine is associated with the regulation of both inflammation and some auditory nervous tissue, drugs that block its receptors in the brain are currently proposed as treatments for tinnitus. Darius Kohan is renowned for his otology expertise and has been highlighted on several outlets such as a CBS spotlight on tinnitus and is often cited in WEB MD and other medical outlets. Since it is a multi-dimensional problem different types of treatments are used to tackle it. The abnormal noise that seems to stem from the ear or head becomes dominant especially if there is pin drop silence. Just like white light is a mixture of the complete spectrum of colors of light similarly the white noise is a mixture of the entire spectrum of audio frequencies that human beings can hear.
Its use prevents the tinnitus noise from becoming too much prominent at night due to absence of environmental noise. As a matter of fact, tinnitus noise can be quite frustrating when it distracts at time when one needs to focus. Hence ALL sounds, low and high, vibrate that region to some extent while traveling to its point of destination. This suggests some protective effect that the apical (low freq) region has that the base (hi freq) doesn’t.
I mean the ear is doing some kind of Fourier transform of the incoming audio signal, did some people try to reproduce this with mechanical devices (so that we can calculate FFT of signals with a device instead of first sampling the signal and then applying some algorithms on it to get the frequency domain content of the sound)? Ringing in the ears is a prevalent disoder called tinnitis, and represents a disorder of the nerves that connect the hair cells to the brain. Other cases may be related to exposure to very loud or destructive levels of noise, such as from an explosion, industrial equipment or farming equipment. Others have found associations between increased activity in further brain regions, age of tinnitus onset and distress caused by the syndrome. However, treating this deficiency had no significant effects on the complaint in these patients.
Other new and emerging treatments for tinnitus focus on the potential indicated by the studies into its links with abnormal brain activity, as mentioned earlier. This makes it difficult for the tinnitus suffers to go to sleep at night because of the silence. The amount you are born with is it, and they gradually die as you expose them to loud noises (and certain drugs).
This makes a lot of sense considering that the freq which are most important are lower ones, like you pointed out, human speech.
While everyone experiences this ringing or buzzing to a slight degree, some people experience it ALL the time.
It is called a cochlear implant, and instead of replacing the entire ear per se, it interprets sound waves as electrical impulses which it transfers directly to the auditory nerve.
Tinnitus may have a significant negative impact on the life quality of those affected by it.

Different research groups have concluded that chronic tinnitus may be associated with an impaired connection between the cerebral cortex, which controls advanced functions such as memory, perception of the environment and cognition, and the thalamus, which supplies the cortex with sensory information. A recent study, including 974 patients, indicated that hearing aids were preferable and more effective in treating blast-related tinnitus compared to noise generators. Presuming further research confirms the findings of these studies, deep brain stimulation (a form of implant placed in the brain to correct this activity) may be a viable option for severe treatment-resistant tinnitus.
During daytime the problem gets somewhat less troublesome since there are other noises that can partially mask the tinnitus noise.
But the cochlea is still able to perceive pain in the ear (this occurs with high frequencies often), even when hair cells are gone. This, in turn, equates more mechanical trauma for the region and likely contributes to a shorter life of the cell. This process happens at different rates for different people, due to environment and genes.
An entering sound wave will vibrate a certain portion of the basilar membrane (frequency is rate of vibration), and since the hair cells sit atop this membrane, they too will receive stimulation.
There is also a line of thought that many cellular and maturational process occur in a basal to apical cascade: inital inner ear development goes this way, as does apoptosis following acute trauma.
They are particularly effective in relaying sound where before there was none, but it takes a long time to train yourself to discriminate what you are hearing. This syndrome may also have deleterious effects on the emotional, psychological and functional status of the patient. Prolonged exposure to loud noises (rock concerts, jackhammers, etc) is the most common cause, but there exist others such as certain tumors, some antibiotics, fluid in the ear, etc.
Speech never sounds the same again (it is skewed towards hi freq so everyone sounds squeaky), and music cannot be perceived.
That is the hearing we are all born with, and it progressively worsens with age as we lose hair cells that sit on a particular portion of the basilar membrane. There are no real treatments for it, except perhaps cognitive therapy or masking the tinnitus with white noise. The implant cannot recreate the ear’s fine-tuned frequency and tone discrimination, but it can help a profoundly deaf person function better in their environment. That means that even the young people who could hear the 17kHz beep have still had some hearing loss, and quite naturally.
I think that the state of these implants is still rather crude, but there is every reason to think their sensitivity will only get better. We lose hair cells starting at the highest (20kHz) first, working our way down the frequency spectrum as we get older.
