There is no shortage of medical evidence regarding the dangers of secondhand smoke, ranging from low birthweight and birth defects to respiratory tract infections and lung cancer. Adolescents who are exposed to secondhand smoke are almost 2% more likely to experience low-frequency hearing loss than those who are not exposed. It is thought that secondhand smoke enters through the ear opening and causes damage. Researchers analyzed data from the 2005-2006 National Health and Nutritional Examinations Survey. What was found was that as blood toxicity from nicotine rose, so did hearing loss at low frequencies. Researchers noted that it was likely that this hearing loss would progress as the subjects aged.
Findings of this study strongly suggest that teens who are exposed on a regular basis to secondhand smoke should have their hearing tested.
It is unfortunate it that big tobacco knew of issues revolving around smoke and secondhand smoke, but haven’t had to admit it until now.

Severe head trauma can dislocate middle-ear bones or cause nerve damage, causing permanent hearing loss.
Noncancerous growths, including osteomas, exostoses, and benign polyps, can block the ear canal, causing hearing loss. Information from 799, non-smoking teens ages 12 to 19 exposed to toxic secondhand smoke was used. Additional concern was noted that the greatest amount of hearing loss occurred at levels that were responsible for clarity of hearing that helps us differentiate between similar sounding words.
Those that smoke around teens should also be aware of the impact that secondhand smoke has on hearing as well as overall health.
WorkersThe Right Kind of Guesswork: If your student has trouble making inferences, knowing why the student struggles is the first step in deciding on a treatment strategy. Sudden changes in pressure -- from flying or scuba diving -- can lead to damage to the eardrum, middle ear, or inner ear and hearing loss. This causes the eardrum and tiny bones, called the hammer and anvil, in the middle ear to vibrate.
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.
The teens were separated into four groups after their blood was measured for toxic byproducts of nicotine, with group 1 having the least exposure and group 4 having the most exposure. Future studies are merited to investigate the impact that hearing loss has on such things as academic performance, cognitive and behavioral function and public health costs.

Then vibrations travel to the fluid in the cochlea where microscopic hairs send nerve signals to the brain so sound is understood. Acoustic neuroma (an inner ear tumor shown here), grows on the hearing and balance nerve in the inner ear.
Though congenital hearing loss often runs in families, it can occur with maternal diabetes or an infection when pregnant. Usually, age-related hearing loss is caused by the progressive loss of inner-ear hair cells.
Autoimmune diseases, such as rheumatoid arthritis, also can be linked to some forms of hearing loss. 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.
Diseases known to affect hearing in children include chickenpox, encephalitis, influenza, measles, meningitis, and mumps. 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. 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.
