Hearing Health Foundation aims to educate Americans about safe listening levels and how to prevent noise-induced Hearing Loss. Every day, we experience sound in our environment, such as the sounds from television and radio, household appliances, and traffic.
Scientists once believed that the pure force of vibrations from loud sounds caused the damage to hair cells.
When a person is exposed to loud noise over a long period of time, symptoms of NIHL will increase gradually.
Although being aware of decibel levels is an important factor in protecting one’s hearing, distance from the source of the sound and duration of exposure to the sound are equally important. Exposure to harmful sounds causes damage to the hair cells as well as the auditory, or hearing, nerve. Continuous exposure to loud noise also can damage the structure of hair cells, resulting in hearing loss and tinnitus, although the process occurs more gradually than for impulse noise. People of all ages, including children, teens, young adults, and older people, can develop NIHL. Block noise by wearing earplugs or other hearing protective devices when involved in a loud activity (special earplugs and earmuffs are available at hardware and sporting goods stores).
If you suspect hearing loss, have a medical examination by an otolaryngologist (a physician who specializes in diseases of the ears, nose, throat, head, and neck) and a hearing test by an audiologist (a health professional trained to measure and help individuals deal with hearing loss). The National Institute on Deafness and Other Communication Disorders (NIDCD) researches the causes, diagnosis, treatment, and prevention of hearing loss. NIDCD researchers also are investigating a potential way to prevent NIHL after noise exposure.
NIDCD maintains a directory of organizations that can answer questions and provide printed or electronic information on NIHL.
My name is Mary Grace and I have otosclerosis which has caused me to slowly lose my ability to hear over the last 35 years. The treatment focuses on the fact that hearing problems such as tinnitus are linked to excessive amounts of glutamate. Glutamate plays a key role in the way nerve cells such as those in the ear (in the auditory nerve) communicate with the brain. Normally, the auditory nerve carries signals which the brain decodes into what we understand as sounds.
However, when hearing problems develop, this can lead to too much glutamate being produced. The new drug - named AM-101 - is thought to block the auditory nerve, stopping it from misfiring. A clinical trial of the treatment, developed by Switzerland-based Auris Medical, is being carried out in 20 centres throughout Germany. The researchers say it is not known whether there is a 'window' during which AM-101 is effective, or how long such a window could last.


The study reports that such travellers are often exposed to levels that exceed recommended limits. The damage can be caused by a single exposure to a loud noise, such as an explosion, but more often is linked to continuous or chronic exposure to loud sounds over time. In the American study, researchers found subway passengers were exposed to the highest levels of continuous noise, but all methods of public transport could be a potential problem. The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline. This simple technique recently discovered by scientists at leading medical universities is the best way to permanently silence the noise blaring inside your ears. Instead, recent studies have shown that exposure to harmful noise triggers the formation of molecules inside the ear that can damage or kill hair cells. Over time, the sounds a person hears may become distorted or muffled, and it may be difficult for the person to understand speech. For example, the humming of a refrigerator is 40 decibels, normal conversation is approximately 60 decibels, and city traffic noise can be 85 decibels.
If a person regains hearing, the temporary hearing loss is called a temporary threshold shift. All individuals should understand the hazards of noise and how to practice good hearing health in everyday life. Listening to an mp3 device at maximum volume (usually around 105 decibels) for more than 15 minutes per day may cause a permanent hearing loss. Most hearing loss is caused by damaged hair cells, which do not grow back in humans and other mammals.
Noise exposure triggers the formation of destructive molecules, called free radicals that cause hair cell death. Laboratory research showed that a single dose of the drug cured tinnitus in people with noise-induced hearing loss. The excess of glutamate is thought to trigger a misfiring of the auditory nerve, which results in inappropriate signals being sent through to the brain, causing tinnitus. During the procedure and for 30 minutes afterwards, patients have to lie on their side with their treated ear facing upwards, to allow for maximum penetration of the drug into the ear. The patients being treated have developed tinnitus following exposure to loud noise within the previous three months. Tinnitus as a result of noise trauma can be distressing and debilitating for those who experience it. Someone with NIHL may not even be aware of the loss, but it can be detected with a hearing test. Sources of noise that can cause NIHL include motorcycles, firecrackers, and small firearms, all emitting sounds from 120 to 150 decibels. The temporary threshold shift largely disappears 16 to 48 hours after exposure to loud noise.


NIDCD-supported researchers have helped to identify some of the many genes important for ear development and hearing.
Researchers initially had thought that antioxidants, chemicals that protect against cell damage from free radicals, might prevent NIHL only if the antioxidants were given before noise exposure.
The results may lead to one of the first drug treatments to be licensed for noise-induced tinnitus,' says Dr Mark Downs, RNID's executive director of science. Hearing loss and tinnitus may be experienced in one or both ears, and tinnitus may continue constantly or occasionally throughout a lifetime. You can prevent NIHL from both impulse and continuous noise by regularly using hearing protectors such as earplugs or earmuffs. Recreational activities that can put someone at risk for NIHL include target shooting and hunting, snowmobile riding, woodworking and other hobbies, playing in a band, and attending rock concerts.
In a recent study, however, the antioxidants in salicylate (aspirin) and Trolox (vitamin E) were given to guinea pigs as long as three days after noise exposure and still significantly reduced hearing loss.
These results suggest that there is a window of opportunity in which it is possible to rescue hearing from noise trauma. I am humbled by this technology that transforms me into someone who can participate in a rich an full life. Most tinnitus comes from damage to the inner ear (see Figure 1) , specifically the cochlea.
This experiment is the first successful demonstration of gene therapy that improves hearing in formerly deaf animals.
This is the type of scientific advance that we hope to harness, in our Hearing Restoration Project, to develop the first genuine cure for hearing loss.
If a specific cause for tinnitus is determined, it is possible that treating the cause will eliminate the noise.
Some of the medications we rely on to cure illness may also be harmful to our hearing health. Several research groups have investigated the effect of cervical spine treatments on CST 11, 12. The aim of this study was to evaluate the effect of a new treatment consisting of stretching. Again, the good news is that a chiropractor can treat this so this somatic tinnitus almost fades away. When my head is straight my tinnitus is about a 2 (from 1-10) often times I don’t hear it at all (or notice it).
