Hearing High Pitch Sound: Tinnitus Explained
Millions of people suffer from hearing noises that only they can hear. The condition of incessant noise perception is called tinnitus. The noise originates internally, so a tinnitus sufferer hears the noise even if he covers his ears. Majority of people with this condition testify they are hearing high pitch sound. Tinnitus can be benign, but it can also be intrusive and can give rise to other problems like depression, anxiety, and insomnia.
How Tinnitus Occurs
Ringing in the ears or tinnitus is due to an abnormality in the auditory system. Usually it is caused by damage to the inner ears brought about by repeated exposure to loud noise. Since the beginning of industrialization, the world has become a noisier place. Technology somehow wrecked many ears.
What happens is that loud noise destroys the tiny cells in the cochlea called the hair cells. These cells transmit auditory signals to the auditory nerve, which in turn transmits the impulses to the brain. The brain processes the impulses, and that is how you hear.
When hair cells are damaged, they function in a funny way. They fire random signals. The brain picks such random signals as noise. According to scientists, this is how you hear the internal noises. The bad thing is that damage to hair cells is irreversible. No cure has been invented yet to correct this damage.
Tinnitus and Hearing Loss Connection
Many people with tinnitus have some form of hearing loss, and at the same time many people with hearing loss also have tinnitus. The connection between is easy to understand, considering both are caused by similar factors. Noise that destroys the hair cells may cause sensorineural hearing loss as well as tinnitus. However, researchers have pointed out a more complex generation of tinnitus, in which the neural auditory pathways are involved. Activation of certain neural networks, for instance, has been observed in studies. Brain imaging scans have also displayed overactive sites in the brain in people with tinnitus.
Scientists believe that when people suffer from hearing loss, the brain tries to compensate to the lack of auditory input. Some neurons are activated and the brain’s awareness to any available impulse is heightened. This is responsible for the perception of internal noise that is usually absent in normal individuals. The brain’s awareness is heightened when it receives less amount of auditory impulse. This explains why even people without hearing loss may hear such phantom noise under extremely quiet conditions.
Degrees of Tinnitus
Most people with tinnitus suffer from mild ringing only. Mild tinnitus usually does not need medical attention because it only becomes apparent under quiet conditions. It cannot be heard during daytime amid the environmental noise. Moderate tinnitus is more intrusive, with sufferers hearing high pitch sound at certain times of the day. Moderate ringing in the ears can be managed through masking. Severe tinnitus is the most intrusive and may be present even when your surrounding is noise-laden. Simple masking will not alleviate severe tinnitus in most cases.
What Tinnitus Sounds Like
The experience of having tinnitus varies from person to person. Generally it sounds like a high pitch noise or a light high frequency sound that seems to cut through your ear. Some people say that they seem to hear a hovering noise. While many hear a high pitched single tone, others hear multiple tones. There are also cases of tinnitus which are described to have no tonal properties (thumping or roaring noises inside the ears). There is no exact explanation why such differences occur.
Unilateral and Bilateral Tinnitus
Tinnitus patients either hear one or both ears ringing. If only one ear is ringing, it’s called unilateral tinnitus. If both ears are ringing, it’s called bilateral tinnitus. More people suffer from unilateral tinnitus, but bilateral tinnitus is not uncommon either. One-side ringing is commonly associated with hearing damage or noise-induced damage and hearing loss. Other causes are Meniere’s disease or acoustic neuroma. Bilateral tinnitus occurs in a number of patients with cardiovascular problems. Many cases involve tinnitus that is more pronounced in one ear.
Subjective and Objective Tinnitus
A huge proportion of tinnitus statistics involves cases of subjective tinnitus. This type of tinnitus is only heard by the patient himself. More than 90 percent of the people with tinnitus have this form of the condition. No instrument has been invented yet that can detect the presence of this tinnitus. Doctors only rely on the testimony of the patient during the assessment. The amount of masking needed may determine the degree of tinnitus though.
Objective tinnitus can be detected by someone else. A doctor using his stethoscope can detect the noises heard by the patient, although not all the time. Objective tinnitus is commonly due to abnormal blood circulation in the ears or near the ears brought about by cardiovascular problems and abnormal formation of blood vessel networks in or around the ears.
Idiopathic Tinnitus
Treatment for tinnitus involves determining the cause. However, about half the cases of tinnitus have been reported to exist alone without a causative disorder. Since tinnitus is classified as a symptom and not a disorder, then it’s only appropriate that a disorder is present when tinnitus is diagnosed. The absence of a disorder indicates idiopathy. Idiopathic tinnitus is treated through conventional methods like masking, cognitive behavioral therapy, and alternative therapies.
Living with Hearing Disorders
The hearing is a complex system in the body that operates in such a complicated fashion. Yet you hear at such a rapid speed that you can take the entire process for granted. Who would have time to bring to consciousness such a process? Then again, we only realize the importance of our hearing once we suffer from hearing disorders.
There are a number of common disorders that affect the hearing. Some of them are not really classified as disorders but bring considerable discomfort and intrusiveness, just like disorders do. A hearing disorder can occur at birth or it may develop as a person grows. It can also be a result of an injury or a complication of an illness. Nonetheless, any hearing disorder is characterized by abnormal hearing. It can be plain below average hearing sensitivity, hypersensitive hearing, or hearing of non-existent noises.
Hearing Loss
There are generally two types of hearing loss, which are conductive and sensorineural hearing loss. The former is caused by earwax, ruptured eardrum, or fluid buildup in the middle ear. Bone abnormalities in the ears can also cause conductive hearing loss, which occurs when the sound waves that pass through the ears are not transmitted properly. That results in muffled hearing, which can last for as long as the abnormality or blockage remains in the ear.
Sensorineural hearing loss is caused by damage to the nerve that conducts impulses from the ears to the brain. This damage is usually caused by exposure to loud noise. It can also be caused by a tumor or an infection. Aging may also lead to sensorineural hearing impairment that is believed to be a result of cumulative damage sustained over the years. Use of medications may also cause degeneration of auditory nerve fibers, and this can also result in either temporary or permanent hearing damage.
The treatment for hearing loss depends on the type and cause. Blockage in the ears, which causes conductive hearing loss, can be removed through simple procedures. For instance, impacted earwax can be removed by an otologist or even a GP. The patient can go home afterwards. Ear infections, which result in temporary hearing loss, can be treated using antibiotics.
Sensorineural hearing loss can be managed through wearing of hearing aids, which amplify incoming sound so it could be heard more easily. Hearing aids today have been significantly improved to optimize amplification of certain frequencies. Studies show that people with hearing loss usually have problems hearing certain frequencies. Hence, hearing aids are adjusted to amplify only the affected frequencies.
Ringing in the Ears
Millions of people suffer from this strange condition characterized as perception of ringing noise inside the ears. This condition is called tinnitus, and it is a peculiar subject in the area of audiology. The often misunderstood condition is said to be a symptom of a disorder. However, the culprit is sometimes unidentified.
Experts believe that the usual cause of tinnitus is loud noise exposure. This explains why many musicians and factory workers suffer from this condition. It also explains why it is associated with sensorineural hearing loss. Tinnitus can be triggered by stress or ototoxic medications like aspirin. It may be temporary or permanent. It can exist in one ear or both ears.
There is no cure for tinnitus, but there are many ways to manage it. One is through maskers, devices that emit a steady stream of broadband noise. Tinnitus maskers provide relief by making the ringing inside the ears imperceptible. Once the masker is turned off, tinnitus becomes perceptible again. That is the major limitation of masking devices. On the other hand, if you have hearing loss at the same time, you will be advised to wear hearing aids. The amplification of external sound diminishes the perception of internal noise.
Other treatments for tinnitus include homeopathic remedies, which provide relief without causing side effects. Natural remedies usually work by activating the healing mechanism of the body. Other alternative treatments are acupuncture, acupressure, and herbal treatment.
Hyperacusis
Some people are intolerant to noises and may have exaggerated reactions to noises, which do not at all bother others. They are suffering from sensitive hearing or hyperacusis. Another form of sound intolerance is misophonia, which is a selective type of noise intolerance. It is hard to pin down the causes of hyperacusis, but experts think inner ear damage due to loud noise exposure or aging is the culprit. Just as the cause is hard to determine, it is also hard to find a suitable treatment. In most cases, afflicted individuals would have to live with the condition. Retraining therapy can help people with abnormally sensitive hearing. Wearing of masking devices is said to bring about relief. There remains no definite treatment procedure for hypersensitive hearing.
Advice to Everyone
Regular screening of the hearing is important to detect early signs of hearing disorders. It is recommended that people be screened for hearing loss every three years. Those who work at acoustically hazardous environments should have hearing assessment more often. Go to your doctor, too, if your ears are ringing or if you have developed abnormal sensitivity to certain sounds or noises.
Advice for People with Muffled Hearing
People can suffer from hearing loss, which can be due to exposure to very loud noise or adverse reactions to medications. Ear infections and head injuries may also lead to hearing problems. Sometimes, you fail to notice you have muffled hearing or you deny the signs that your ears are no longer functioning properly.
One important advice is to recognize the signs of hearing loss, which include inability to understand speech and conversations, asking people to repeat themselves, turning the volume of the television louder than other people at home prefer, the presence of a constant ear ringing and having trouble understanding people in noisy background.
You should go to your doctor for medical evaluation. Different factors result in hearing loss. Many causes of hearing loss are irreversible. The common cause is exposure to loud noise. Some causes of hearing loss can be corrected. Such causes include cerumen impaction and eardrum perforation.
Sensorineural hearing loss, on the other hand, cannot be reversed and can only be addressed through hearing aids. An ear specialist can evaluate the degree of your hearing impairment and adjust a hearing aid to match your hearing loss. You cannot buy a hearing aid by yourself.
Once your hearing has gone muffled, you can no longer expose your ears to loud noises. Stereos at home should be kept at moderate volumes. You should be concerned about the medicines you take because many can harm your ears and can actually cause other unwanted ear conditions such as tinnitus problems.
How to Prevent High Frequency Hearing Loss
Sensorineural hearing loss is usually characterized by loss of hearing at the high frequencies. It occurs because of nerve damage. It can also bring about ringing in the ears. The usual cause of this type of hearing loss in adults is noise. Excessive noise destroys the hair cells in the cochlea, causing permanent damage. High frequency hearing loss characterizes SNHL in most cases. People who no longer hear high frequencies will suffer an inadequacy in their lives because they can’t hear the world normally.
Prevention requires, first, education. A lot of people seemed to have forgotten the basic ways to prevent hearing loss. The most important reminder is to stay away from loud noise to avoid damage to the inner ears. Avoiding loud music and keeping volumes of iPods and portable music players within moderate levels. Wearing earplugs should be imperative for people who are frequently and inevitably exposed to loud sound. Earplugs preclude hearing damage such as ears ringing by lowering the sound input to the ears.
Prevent Hearing Disorder Through These Tips
The best way to prevent hearing disorder is by staying away from loud noise. The most common cause of hearing loss is repeated exposure to loud noises, such as car horns, machinery noise, and loud music. People who work in noisy places are highly prone to hearing loss. At the same time, musicians are also likely to get hearing impairment. Many people suffering from sensorineural hearing loss are band members and musical conductors, who are frequently exposed to high decibel sound. When this happens, they may not only have to look for a relief for hearing loss but also other cures like a ringing ears treatment to treat the other hearing problems that they may have acquired.
Another way to keep your ears safe is to stop putting anything in your ears. Poking your ears is also harmful in a few ways. First, you can scratch your ears. Second, you can push your earwax deep. Third, you can puncture your eardrum. Using Q-tips to clean the ears is not recommended. In fact, removing the earwax is never recommended by specialists. The ears have their own efficient way of cleaning themselves up.
Treat ear infections right away. Earache should warrant you to go to your doctor. Don’t wait until a nasty goo comes out of your ears. Ear infections can be treated successfully using antibiotics, but seek your doctor’s recommendation. Such infections can worsen and cause conductive hearing loss when left untreated.
Most people often wait for such a time when they have go to the doctor to get a treatment for their ear problem such as a tinnitus cure. A useful advice ignored by many people is to go to your otolaryngologist for a regular hearing assessment. This is one thing you must always consider.
