 According to a February 2015 news release, the World Health Organization has reported that about 1.1 billion teenagers have been found to be at risk of developing hearing problems. The primary reason attributed to this alarming statistic is the frequent use of Ipod, MP3 players and smart phones, and also the high exposure to noise pollution at public entertainment facilities like discos or nightclubs.  Musicians are also at increased risk of hearing loss.

WHO’s report has particularly singled out the 12-35 years age-group from middle-class and affluent families who routinely listen to loud music are developing hearing loss.

By definition, any individual exposed to over 85 db of noise for more than 8 hours at a stretch is a high-risk individual for hearing loss.

The risk of damage to hearing from music depends on:
  • Loudness of the music
  • Closeness to the source of music/ speakers
  • Duration of exposure to loud musi
  • Family history of hearing loss
  • Individual susceptibility to noise
The adverse effect of noise on the teenager’s ears

 Typically during New Year parties or other similar festivities, sound levels are very high before people realize, they may experience a sudden numbing sensation in the ears followed by a deafening silence! This experience differs from person to person, but teenage party-goers frequently complain about hearing problems after attending a rock concert or a whole-night party. Many of these teenagers who complain about temporary hearing loss from time to time may develop serious problems later in their lives, as indicated in Noise induces hearing loss.

Teenagers from low-income groups working at mines, construction sites, oil drills are at same risk of developing hearing loss because of the nature of their occupational environments.

How to know noise is harmful:
  • If you have to shout to be heard
  • You have pain in the ears be cod noise
  • If there is ringing in the ears
  • If ears feel muffed or reduced hearing
What are some practical solutions to reduced music related damage?

Protect your ear from the new year’s noise suggests some practical ways to avoid hearing problems.

  1. Turn down the volume of personal music systems
  2. Take regular breaks from loud music or go to less noisy areas from loudest areas in club or
  3. Stand away from the sound source or music speakers
  4. Use noise cancelling head phones
  5. Wear ear plugs. This solution is recommended for young, professional musicians too.
  6. Custom-fit musician earplugs can be used.

The deafening volumes of music played at nightclubs, discos, and parties are simply exposing the young adults to life-threatening sound pollution, which will sooner or later, become an uncontrollable malady of teenage lifestyle all over the world.

 

If any teenager experiences noise-induced irritability, ear block, buzzing, or ringing in the ear, he should immediately consult an ENT Specialist and Hearing test by audiologist is to be done.

 

You Can Permanently Lose Your Hearing From Exposure to Diwali Noise

Any sound above 85 dB has the potential to harm our ears. The noise levels in most urban areas are very high which further goes up to dangerously high levels during Diwali- Fireworks and fireworks,  music systems… soon it may end up with visit to ENT and Audiology clinics.

E.N.T. Care and Cure

A teenage girl visited ENT clinic with her mother with ringing in the ear and felt like cotton in the ear. Previous night,  Diwali Night she had spent several hours setting off the fire crackers.

Her ear were normal on video otoscopy and Audiogram showed  35 db at 4000 and 8000 hertz, Several days later, her hearing had returned to normal.

This patient is an example of a “temporary threshold shift.” Or Reversible Hearing Loss by exposure to an intense “impulse” sound such as fireworks or loud rock concert.

If sound is too loud or duration of exposure is long enough, such as noise generated in a woodworking shop it may lead to permanent threshold shift.  This condition is called Noise Induced Hearing Loss which has no cure.

Noise Induced Hearing Loss

A teenage girl visited ENT clinic with her mother with ringing in the ear and felt like cotton in the ear. Previous night,  Diwali Night she had spent several hours setting off the fire crackers.

Her ear were normal on video otoscopy and Audiogram showed  35 db at 4000 and 8000 hertz, Several days later, her hearing had returned to normal.

This patient is an example of a “temporary threshold shift.” Or Reversible Hearing Loss by exposure to an intense “impulse” sound such as fireworks or loud rock concert.

If sound is too loud or duration of exposure is long enough, such as noise generated in a woodworking shop it may lead to permanent threshold shift.  This condition is called Noise Induced Hearing Loss which has no cure.

Acoustic trauma occurs when excessive sound energy strikes inner ear. When we are exposed sounds that are too loud or loud sounds that last a long time—small sensitive structures in our inner ear, called hair cells, can be damaged, Hair cells convert sound energy into electrical signals that travel to the brain. The louder the sound, the shorter the time period before NIHL can occur.

Sound is measured in units called decibels. Continual exposure to more than 85 decibels (dB) is dangerous to the ears. Firecrackers emit sounds from 120 to 160 decibels. Sound with 140dB can cause ear ache. A very high intensity sound (above 160 dB) may also damage the ear drum and can cause dislocation of middle ear ossicles.

An even higher intensity may cause leakage of inner ear fluid leading to permanent hearing loss associated with dizziness.

Symptoms

  • Hearing loss
  • Sense of fullness  the ear
  • Noises, ringing in the ear
  • Earache
  • Bleeding from the are
  • Dizziness,

Signs and tests

Acoustic trauma is suspected if hearing loss occurs after noise exposure. Audiometry may determine how much hearing has been lost. Audiogram has typical “notch” at 4000 hz, with better hearing at both lower and higher frequencies. Otoacoustic Emisson (OAE) testing is very sensitive to noise induced hearing loss.

Treatment

The hearing loss may not be treatable. The goal of treatment is to protect the ear from further damage. Hearing aid is prescribed for communication needs. If ear Drum is ruptured, surgery to repair ear drum may be needed.

Ear protection using noise protector ear plugs or ear muffs may prevent the hearing loss from getting worse.

Noise exposure, whether occupational or recreational, is the leading preventable cause of hearing loss. It can be prevented by avoiding “too loud” or “too long” Noise exposure and use of hearing protection when necessary.

Noise and Ear

On International Noise Awareness Day, 28th April 2010

The Center for Hearing and Communication founded International Noise Awareness Day to promote awareness of the dangers of long-term exposure to noise.

Everything you need to know about the noises you’re exposed to every day. Discover which noises could be damaging to your hearing and learn steps you can take to prevent hearing loss due to noise at http://www.chchearing.org/noise-center-home/facts-noise

Noise and ear:

Excessive noise exposure is the most common cause of hearing loss.

Too loud noise damages sensitive nerve endings in the inner ear (delicate cells called cillia) and causes sensorineural hearing loss. It can be reduced or prevented all together.

Sudden exposure to loud noise may cause temporary sensorineural hearing loss which usually recovers over 24 to 48 hours.

But if sound is too loud, or loud sound is too close or loud sound is exposed over a long period of time (more than 85 db), permanent sensorineural hearing loss can occur.

And 85 decibels is not as loud as you will think.  Sound from an iPod shuffle is usually 115 db, and with fireworks it goes at 150 db. Not only Large bore guns and artillery But even cap guns and firecrackers can damage your hearing if the explosion is close to your ear.

What is Dangerous level of noise?

Sensitivity to sound is different for each person.

Noise may damage your hearing if you have to shout over background noise to make yourself heard, the noise hurts your ears, it makes your ears ring, or you have difficulty hearing for several hours after exposure to the noise.

Approx. Decibel Level Example
0 Faintest sound heard by human ear.
30 Whisper, quiet library.
60 Normal conversation, sewing machine, typewriter.
90 Lawnmower, shop tools, truck traffic; 8 hours per day is the maximum exposure to protect 90% of people.
100 Chainsaw, pneumatic drill, snowmobile; 2 hours per day is the maximum exposure without protection.
115 Sandblasting, loud rock concert, auto horn; 15 minutes per day is the maximum exposure without protection.
140 Gun muzzle blast, jet engine; noise causes pain and even brief exposure injures unprotected ears. Maximum allowed noise with hearing protectors.

Occupational exposure to noise

People with occupations involving exposure to noise above 85 decibel over an 8 hour period daily are also at risk. These include industries like mining, construction, drilling and agriculture.

For unprotected ears, the allowed exposure time decreases by one-half for each 5 dB increase in the average noise level. For instance, exposure is limited to 8 hours at 90 dB, 4 hours at 95 dB, and 2 hours at 100 dB

The highest permissible noise exposure for the unprotected ear is 115 dB for 15 minutes/day. Any noise above 140 dB is not permitted.

Noise exposure is cumulative. So the noise at home or at play must be counted in the total exposure during any one day.

If you must work in an excessively noisy environment, you should wear protectors.

* Person working in noise above 85 db should use noise protection devices-ear plugs and ear muffs. It is as simple a concept as using goggles to protect your eyes from UV rays of sun. It should also be used by musicians and when using power tools, noisy yard equipment, or firearms.

Do periodic hearing check ups with annual hearing test (pure tone Audiometry).

Ear Protectors

Hearing protection devices decrease the intensity of sound that reaches the eardrum. They come in two forms: earplugs and earmuffs.

Earplugs are small inserts that fit into the outer ear canal. They must be snugly sealed so the entire circumference of the ear canal is blocked. They are available in a variety of shapes and sizes and can be custom made.

Earmuffs fit over the entire outer ear to form an air seal so the entire circumference of the ear canal is blocked, and they are held in place by an adjustable band.
Properly fitted earplugs or muffs reduce noise 15 to 30 dB. Simultaneous use of earplugs and muffs usually adds 10 to 15dB more protection than either used alone. Combined use should be considered when noise exceeds 105 dB.

Cotton balls or tissue paper wads stuffed into the ear canals are very poor protectors.

On earliest sign of noise trauma like irritability, buzzing sound in ear or difficulty in hearing, trouble understanding what people say;  especially when you are in a noisy place such as in a crowd or at a party. This could be the beginning of high-frequency hearing loss; a hearing test will detect it.
visit your physician.

Few more tips

  • Turn down volume of MP3 player/television.
  • Do not stand directly near to the source of noise.

Happy new year and “safe ear”- protect ear from noise

Noise-induced Hearing loss

  • Noise level goes up with new year celebrations, social gatherings, party, music, rock-concert and fire works, and so does people visiting E.N.T. and audiology clinics with hearing problems or ringing in the ear(tinnitus).

· Children and teens listening to loud music are also more prone to develop hearing loss later in life.

· People with occupations involving exposure to noise above 85 decibel over an 8 hour period daily are also at risk. These includes indusries like mining, construction, drilling and agriculture.

  • And now people who love to play golf using latest titanium drivers are at risk of reduced hearing because of noice generated when it strikes the ball. (ref-British medical journal)

How noise causes hearing loss?

Too loud noise damages sensitive nerve endings in inner ear (delicate cells called cillia) and cause sensorineural loss. Sensitivity to sound is different for each person.

Sudden exposure to loud noise may cause temporary sensorineural hearing loss which usually recovers over 24 to 48 hours.

But if sound is too loud, or loud sound is too close or loud sound is exposed over a long period of time(more than 85 db), permanent sensorineural hearing loss can occur.

And 85 decibels is not as loud as you will think. Sound from an ipod shuffle is usually 115 db, and with fireworks it goes at 150 db.

Tinnitus may be presenting complaint for some person.

  • Person working in noise above 85 db should use noise protection devices-ear plugs and ear muffs. It is as simple a concept as using goggles to protect your eyes from UV rays of sun. It is for Musicians also.
  • · People with occupations involving noise exposure should undergo periodic hearing screening(audiometry test).

    · On earliest sign of noise trauma like irritability, buzzing sound in ear or difficulty in hearing visit your physician.

· Turn down the volume of television and MP3 players.

  • Do not stand directly near to the source of noise.

Unfortunately physician can not do much in sensorineural hearing loss except prescribing a hearing aid. So primary aim is prevention and early detection.
