What Do You Know About Tinnitus?
Anyone who experiences sudden tinnitus and hearing loss in only one ear
, he said, should seek medical help immediately, as the condition can be treated if caught early. Anyone who does browse through the internet should keep an open but cautious mind!
What About Ringing Ears?
Ringing ears are actually symptoms of an underlying condition, or conditions, that you may have. The main causes of ringing ears are problems with the inner ear / auditory nerve, head, neck, and other things like stress, high blood pressure and the overuse of drugs like aspirin. Ringing ears are caused by distorted sound, not the volume. Due to the pretty amazing technology in The Funktion One sound system, we have in Ascension, the system is free from distortion, and thus you hear the music exactly as the producers intended you too, and you can enjoy it without damaging your ears.
Ringing ears, blood pressure, what's the connection? As we all know, many people suffer from a ringing in their ears, which is known as tinnitus. Ringing in the ears may be simply related to advancing aging. In sum, the sound may be related to visual as well as auditory brain activity as found in a study in the February 27 issue of Neurology, a scientific journal of the American Academy of Neurology.
What About Noises?
Noise in the workplace can damage hearing. Hearing damage occurs when noise is higher than 85 decibels, which is about the loudness of heavy traffic. Noise is damaging if you must shout to be heard, if your ears hurt, or if your hearing is lessened immediately following noise exposure. The noise exposure could occur just one time or over months or years. Noise-induced hyperactivity of the DCN, therefore, provides a model for the study of chronic tinnitus mechanisms. This resemblance was made apparent in studies that examined the distribution and levels of hyperactivity along the frequency axis (Kaltenbach Afman, 2000).
Noise-induced hearing loss and inner-ear damage to firefighters (and to other emergency-service workers) has been documented for many years. This occupational damage is commonly manifested by hearing loss that gets worse with the passing of time for the individual. Noises appear to arise in the ears or inside the head and may be experienced all the time, or only intermittently. The causes of tinnitus are not yet fully understood and a variety of treatments are offered including medication, psychotherapy, noise 'maskers' and Tinnitus Retraining Therapy.
What About Research?
Research funded by the American Tinnitus Association focuses on two main areas: mechanisms and management. Read more about tinnitus research in the ATA Research section. Researchers at the pharmaceutical giant Sandoz analyzed ergot in the late 1940s, looking for blood-pressure medications. Of the thousands of compounds that researchers found in ergot, three were combined and tested for their anti-hypertensive properties. Research is ongoing to find the appropriate drugs that may provide effective and long-term relief.
Research has indicated that certain dietary changes can also help reduce the symptoms of tinnitus. Reducing caffeine and chocolate intake has been shown to help reduce tinnitus symptoms in many sufferers. Research indicates that many people can be helped to reduce the perceived level of their tinnitus sound by retraining the brain to pay less attention to it. Where a person achieves a lower awareness of their tinnitus, it is known as habituation. Researchers altered, or notched, each of the target recordings by removing an octave (8 musical notes)-wide range of frequencies centered on the frequency of the corresponding patient's unique tinnitus tone. Placebo recordings were notched by removing several frequency ranges that did not include notes within the tinnitus range.
Research interests center on the neurobiology of tinnitus. Our staff is looking into the brain's role in tinnitus. Research has shown that a high percentage of people with tinnitus is deficient in vitamin B12. Vitamin B12 deficiency has been reported to be common in people exposed to loud noise on the job who developed tinnitus and hearing loss.
Patients should be encouraged to avoid long-term exposure to hazardous noises and to use hearing protection when necessary. Parents should be encouraged to provide adequate hearing protection, such as silicone ear plugs, for their children. Patients actively complaining about tinnitus could thus be assumed to be people who have become obsessed with the noise. This is only partially true. Patients were given 3 mg of melatonin nightly for 30 days. In patients with difficulty sleeping due to the symptoms of tinnitus, an overall improvement was seen in 46% of the study group in contrast to 20% in the group given placebo.
Patients can select a noise generator, hearing aids, music CDs, bedside sound device or use environmental sounds. Progress with habituation is monitored after one month then two months and three months. Patients with severe untreatable psychiatric disorders, those who do not share a common language and those involved in litigation over their tinnitus are the only exceptions in our practice. Patients have described the sensation as similar to the effect of tapping an arm with a pencil.
Various techniques can help make tinnitus tolerable, although the ability to tolerate it varies from a person to a person. Often a hearing aid helps suppress tinnitus. Various combinations of vitamins or supplements are on the market for tinnitus. Most of these uses a combination of antioxidant vitamins or supplements that have been shown to slow age-related hearing loss in animal studies and a few human studies. Various small pharmaceutical companies have begun testing medications that can target particular types of tinnitus, such as a drug that would specifically alleviate typewriter tinnitus. If such trials prove successful, Dr Salvi believes the major drug companies that so far have shied away from tinnitus research could start to pay attention.
