Common Reasons For Hearing Loss

Over 30 million Americans experience some hearing loss. Close to one-third of Americans over the age of 75 have some age-related hearing loss according to the Mayo Clinic. The main reasons for hearing-loss over time are prolonged exposure to loud noise and heredity. But there are a number of other reasons for loss of hearing.

Exposure to loud noises, as mentioned, is one of the most common reasons for hearing loss. Loud noises damage the tiny hairs in the inner ear which are necessary to hearing. Any noise over 85 decibels can be harmful. The following list of noises falls into the harmful range of sound: motorcycles, snowmobiles, chain saws, rock concerts, sirens, jet engines, and gunshots. Listening to loud music, especially with headphones, can cause damage to the ear over time. This type of hearing loss is irreversible. Many jobs also expose workers to loud noises which can damage hearing over time. Some of these jobs are farmers, construction workers, and people serving in the military.

Not only the decibel level affects hearing, but also the length of time that you are exposed to loud noises. The longer you are exposed, the more damage to your hearing. Long exposure can actually be more damaging than shorter, louder sounds.

More than half the infants born deaf each year have a hereditary disorder. However, some infants may inherit the tendency to acquire hearing loss later in life rather than manifesting deafness at birth.

Other reasons for hearing loss include medical conditions, such as viruses and bacterias, heart conditions, strokes, and physical injury to the ear or ear infections. There are also diseases that can affect hearing such as the mumps, meningitis, HIV or AIDS, syphilis, and the measles. Medications have also been known to affect hearing.

If the wax builds up to the points where sounds cannot penetrate to the inner ear, sounds can be muffled.In addition, abnormal bone growth in the ear, tumors in the ear, or ruptured eardrums can all cause hearing loss.If you want to know detail visit http://thelondontinnitustreatmentclinic.co.uk
