Author: admin, 18.08.2014. Category: Ring In The Ears

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.

The risk to your hearing from noise exposure depends on how loud the volumes are AND how long you’re exposed to them. A decibel is a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.
One way that noise can permanently damage your hearing is by a single brief exposure to a high noise level, such as a firecracker going off near your ear. The generally accepted standard to monitor any risk to your hearing is based on an exposure to 85 dB for a maximum of eight hours per day, followed by at least ten hours of recovery time (at 70 dB or lower). I keep my earplugs with me pretty much all the time, and especially if I am heading out to see some music or a social event where there might be loud noise (like a bar or sports arena). Lastly, I try to get my hearing checked (and ears professionally cleaned) by my ear, nose, and throat doctor about once a year. A ringing sound in the ear is a common symptom of tinnitusQ: I have a constant ringing sound in my right ear, which can be annoying, especially when I am in a very quiet room. Our cochlear hair cells emit sounds which can be recorded by advanced hearing test equipment.
It can also be related to inner ear disorders resulting from infection, trauma, loud noise exposure, medications and tumours in the pathway of the auditory nervous system.
More commonly, acute tinnitus is associated with sudden hearing loss that develops over 72 hours.
Others will experience distress, inability to rest, frustration, problems with concentration, fears, worries and even headaches. About 75 per cent of patients who have acute tinnitus get better with time because of brain plasticity and adaptation. For the majority of these patients with pulsatile tinnitus, the physicians are not able to hear the sound through auscultation of the head and neck with the stethoscope and generally, no cause is found on X-ray imaging. Another group of patients with audible pulsatile tinnitus (sounds which the physician can hear following auscultation) would require radiographic imaging to exclude small dural arterio-venous fistulas (abnormal connection or passageway between two vessels that normally do not connect) or vascular brain tumours. For many others for whom the cause of the tinnitus is not found on physical examination and even after various investigations, such as magnetic resonance imaging scans to exclude important treatable inner ear conditions, basic counselling, tips on how to avoid silence and the use of enriched environmental sounds can help.

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.
There are certain decibels that you can withstand for longer amounts of time, as they are at a lower deibel level. But hearing damage can also occur gradually at much lower levels of noise, if there is enough exposure over time. I also have a free app on my phone that is a decibel meter so I can measure the noise around me and see if I need to put my earplugs in. Try to make sure your ENT also has an audiologist on staff, as they can run a bunch of tests and check how your ears are fairing. It can result from hearing loss due to impacted ear wax in the ear canal, a perforated ear membrane, middle ear effusion (build-up of fluid) due to nose cancer or infection, middle ear bone scarring due to infection or another condition called otosclerosis (an abnormal bone growth in the middle ear) from a childhood measles infection. Some patients can be affected to the point of developing sleep disturbances coupled with anxiety and depression. The remainder of patients will still hear the noise but they get used to this, while a minority (5 per cent) will need medical help to cope. The patient with audible pulsatile tinnitus needs early management and treatment before further complications set in. Removing the ear wax will help those who have tinnitus arising from blocked external ear canals.
It is a directed counselling therapy and utilises enriched environmental sounds or noise generators to train the brain to adapt to the tinnitus.

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. I definitely monitor the use of my headphones and make sure the volumes are such that I can still hear loud noises like emergency sirens. I started protecting my ears early in my musical career and I was told I have hearing in the 99th percentile. I am a 60-year-old man and I use a hearing aid in my right ear when I conduct training sessions. This has been reported to be present in 17 per cent of the general population and increases to 30 per cent in those more than 65 years old. We generally do not hear these sound energies as our external sound environment will invariably mask them. Most patients in the acute stage of tinnitus will complain of annoyance, impact on their lifestyle and difficulty coping in quiet environments, especially at night, when the tinnitus sound is magnified due to the absence of ambient noise.
In this group of patients, they hear simple, pure tone sounds such as buzzing, cricket noises or high-pitched sounds or a combination of these. One patient described hearing Singapore’s national anthem Majulah Singapura, while another described hearing cries of “hallelujah”. When this is due to sudden hearing loss with no known cause, a trial of steroids, antiviral medications or antioxidant treatments has been reported to improve the hearing and, subsequently, the tinnitus.
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. These vibrate in response to sound waves, while the outer hair cells convert neural signals into tension on a membrane. If I am playing drums somewhere I try to use my in-ear monitors as I can keep an eye (or an ear) on how loud the music is coming back to me.


My ENT actually said, “You have eavesdropping level hearing and can probably hear through walls if you wanted to.” However, most people don’t get it checked until it is way too late. These patients have to be distinguished from a more common group of patients who suffer from schizophrenia.
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.
Then there are sensing and vibrating cells that carry these vibrations to the brain where in the auditory brainstem, these are converted into audible sounds we can recognize. You can see the two charts I added to get an idea of how loud certain sounds are acceptable, and for how long.
If I am in a situation where wedges or floor monitors are used, then I use my earplugs without question.
Another group of patients hear repeated tapping noises because of middle ear myoclonus, a condition that results from twitching of the middle ear muscles. 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.
It’s that same ringing after turning up your headphones too loud while going for a run, rocking that new Kanye track. It is usually resulting from altered blood flow or increased blood turbulence near the ear.
When these hair cells (stereocilia) are overworked (usually exposed to excessive noise levels for long periods of time) they go into shock producing the ringing you hear.
The musician type earplugs are great as they lower a lot of the damaging frequencies and you can still discern pitch, in case you need to sing or adjust intonation on a horn, etc.
I have checked with a doctor and he has found nothing wrong with the ear, but has suggested that I see a specialist. To quote Professor Pawel Jastreboff, the founder of Tinnitus Retraining Therapy: it results from the brain over-compensating for the presence of a small irregularity in the functioning of the cochlea or auditory nerve. Yet others will hear a rhythmic sound, in time with their heartbeat, defined as pulsatile tinnitus. 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. If this happens continuously, they can cease to respond at all to certain frequencies resulting in hearing loss. 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.
That is because there are several different causes for it and most of those are the same conditions that cause hearing loss.
We lose hair cells starting at the highest (20kHz) first, working our way down the frequency spectrum as we get older. The most common cause is noise-induced hearing loss (loud noises causing damage), but it can also be caused from a side effect of some medications or from an abnormally low level of serotonin activity as a couple of examples.
