Teenagers going deff

Teenagers always seem to be the center of attention. this could be due to the fact that we are greatly effected by the new world and its technology. in this articles, it states that hearing loss in teenagers rose by nearly one-third compared with the rate in 1980s and 1990s. The author of the study found this information to be surprising due to the fact that it has been highly publicized about the risk of exposure to high music. in August 18, Journal of the American Medical Association, the scientist report that U.S adolescents with any hearing loss rose from 14.9 percent during the 1988 to 1995 period to 19.5 percent in 2005 and 2006. The article goes on to say that children living under the poverty line are more likely to have hearing lost than kids above the poverty line. Yuri Agrawal, an otolaryngologist hypothesis that poor people have more untreated middle ear infections. "Such infections sometimes damage the inner ear and sabotage hearing." she says.

There are two different pathways in which sound waves produce the sensation of hearing. in air conduction, sound waves move through the air in the external auditory canal (the ear canal between the outside air and your eardrum) the sound waves hit the eardrum and cause the eardrum to move. the bones in the middle ear are connected to the tympanic membrane (eardrums) moves, the movement is transmitted to the bones. these bones are called malleus, the incus, and the stapes.

This article is important because our generation seems to have the most problems. it allows us to be aware of how loud our musics are, and how they can have a permanent affect on us. Most teenagers are aware of the risk, but don't seem to take it seriously. And its better that we educate ouselves about this issue before it becomes worse.
