Ongoing Exposure to Noise on the JobLong-term exposure to continuous loud noise can cause lasting hearing loss. Michael Rothschild, MD, director, pediatric otolaryngology, Mount Sinai Medical Center, New York. National Institute on Deafness and Other Communication Disorders, National Institutes of Health. A potentially permanent hearing loss that affects tens of millions of patients, especially those who are exposed daily to high noise levels. Frequent and long duration of exposure to loud sounds such as in industry, loud music, power tools, lawn mowers or firearms.
Minimize exposure to loud sounds, such as reducing the volume when listening to television or music . The risk of hearing damage can be roughly calculated as "how loud" and "how long" you are exposed to a certain level of sound. EarPeace ear plugs are the best ear plugs for fans at concerts and live events, DJs, musicians, and anyone else that feels their favorite live entertainment is too loud. Example: Being on a dance floor for one hour at 100 dB(A) delivers the same amount of noise energy to the ear (and therefore potential damage) as being on a slightly less noisy dance floor at 97 dB(A) for two hours. EarPeace extends the length of your experience safely, even if you wear it for short periods of time to rest your ears. Every day, we experience sound in our environment, such as the sounds from television and radio, household appliances, and traffic. The American Tinnitus Association is the foremost organization committed to preventing and curing tinnitus.
The Better Hearing Institute has extensive resources on hearing loss, causes and resources.
The National Institute for Occupational Safety and Health has extensive information about workplace regulations for noise levels and sponsors the Dangerous Decibels Project. The National Institute on Deafness and Other Communications Disorders has one of the largest repositories of clinical information on hearing health and sponsors Wise Ears®.
The American Speech Language Hearing Association helps people with speech, language, and hearing disorders receive services to help them communicate effectively. It is intended for general informational purposes only and does not address individual circumstances.
Experts agree that continuous exposure to noise at or above 85 dB(A) can cause hearing loss. Over time, the cumulative effect of symptomless damage can have a serious long-term impact on your ability to hear.

Simply put, a small reduction in volume makes a big difference to the length of time you can safely listen without hearing protection. It also has a Hearing Loss Simulator that has different situations and what it 'sounds like' to people with hearing loss. The project is a public health campaign to reduce Noise Induced Hearing Loss (NIHL) and tinnitus (ringing in the ear) by changing knowledge, attitudes, and behaviors. Since 1999, WISE EARS!® has been a popular national public education campaign to prevent NIHL. It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. If your experience leaves your ears ringing, or dulls your hearing sense, you've been listening to something that's too loud or for too long without proper hearing protection.
When you compound this damage with high-volume sound at concerts or in nightclubs, some level of hearing loss is virtually unavoidable without hearing protection.Turn down the headphones. However, when we are exposed to harmful noise—sounds that are too loud or loud sounds that last a long time—sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss (NIHL). Never ignore professional medical advice in seeking treatment because of something you have read on the WebMD Site.
If you can't speak to someone who is 2 meters away without shouting, there is a good chance the level of noise is high enough to cause damage. Protect yourself when you are at a live music venue, large concert, nightclub or even the movies.
Human hearing does not work linearly in that an increase of 3 dB does not "sound" twice as loud. These sensitive structures, called hair cells, are small sensory cells that convert sound energy into electrical signals that travel to the brain. However, you may still be damaging your hearing even without these outward damage warnings. The perception of twice as loud corresponds to considerably more than twice the total acoustic power.
Typically literature states that 10 dB increase of sound level is heard as "twice as loud". Injury or Pressure ChangesSevere head trauma can dislocate middle-ear bones or cause nerve damage, causing permanent hearing loss. Sudden changes in pressure -- from flying or scuba diving -- can lead to damage to the eardrum, middle ear, or inner ear and hearing loss. Chronic DiseaseCertain chronic diseases that are not directly related to the ear can cause hearing loss.

Autoimmune diseases, such as rheumatoid arthritis, also can be linked to some forms of hearing loss. How You Hear -- Anatomy of the EarSound waves enter the outer ear and travel through the ear canal. This causes the eardrum and tiny bones, called the hammer and anvil, in the middle ear to vibrate. Then vibrations travel to the fluid in the cochlea where microscopic hairs send nerve signals to the brain so sound is understood. Tumors and GrowthsNoncancerous growths, including osteomas, exostoses, and benign polyps, can block the ear canal, causing hearing loss. Acoustic neuroma (an inner ear tumor shown here), grows on the hearing and balance nerve in the inner ear. The average decibel level at a rock show is 110, loud enough to cause permanent damage after just 15 minutes. Hearing damage can occur with extended exposure of any noise over 85 decibels.
Headphones and EarbudsCan others hear the music and lyrics you’re listening to through earphones? Think you have an earwax blockage? Don't try removing the wax with a cotton-tipped swab or by inserting anything else into your ear canal. For more hearing loss information from WebMD, click "Next." Childhood IllnessMany childhood illnesses can cause hearing loss. Ear infections can cause the middle ear to fill with fluid and cause hearing loss that usually clears when the infection and fluid are gone. Diseases known to affect hearing in children include chickenpox, encephalitis, influenza, measles, meningitis, and mumps. Though congenital hearing loss often runs in families, it can occur with maternal diabetes or an infection when pregnant.
Hearing loss can also develop if a newborn is premature or from other causes such as trauma during birth resulting in the infant not getting enough oxygen. Usually, age-related hearing loss is caused by the progressive loss of inner-ear hair cells.
