Sound is a very unique process through the ear, so unique that the question how does hearing exactly take place is proposed. Well hearing occurs because of sound waves that reach the middle ear and vibrates the ear drum. Then the vibrations are made into nerve signals that the brain recognizes as sound. The risk factors that work against hearing are aging, loud noises, hereditary diseases, some medications, and some illnesses, such as an ear infection. Otitis Media is losing hearing due to ear infection. This can and will lead to permanent hearing loss if it is not treated. Some other causes could be the buildup of earwax, damage of the cochlea, and of course ear infections (Jefferies, 1998-1999).
NIHL or Noise Induced Hearing Loss is another great category of how hearing loss is obtained. Ten percent of Americans between the age of twenty and sixty-nine, which is about twenty-two million Americans, are affected by Noise Induced Hearing Loss, but Noise Induced Hearing Loss is totally preventable. You can protect your hearing by paying attention to noises above eighty-five decibels, which is the maximum point of decibels before hearing damage. These are things such as lawnmowers, snow blowers, motorcycles, firecrackers, and loud music. When engaging in any of those types of activities make sure you use some type of ear plugs (Clark, 1999).
