Hearing Impairment will always be broken down in to two alternative diseases. A conductive hearing impairment is caused by some degree of damage to the outer workings of the ear where as Sensorineural deafness is usually attributed to damage cause to the inner ear. Sensorineural hearing loss can be caused by defects that could possibly have been present from a young age, like possibly the cochlea which upon failing to work correctly could lead to some form of hearing loss.
Hearing Damage can have many different reasons for developing and can become apparent without warning. The major reasons for hearing loss can be accredited to age and environmental influence. If you have spent many years surrounded by loud noises the likely hood of suffering some form of hearing loss will dramatically increase.
The natural loss of hearing due to age is known as Presbycusis and can be brought on at any time in your life though symptoms begin in your early adult life. In most normal circumstances this loss of hearing will be unnoticeable at first though you should take note that the condition can be increased greatly through outside noise pollution, disease or exposure to toxins.
Environmental Noise can be a large factor in hearing loss and an increase in cases has been attributed to the industrialization of certain areas. People who stay closer to freeways and airports where sound levels regularly jump above 65 Db are more like to suffer from Noise-induced hearing loss, which is commonly known as NIHL.
Some medicines can cause a loss of hearing as a side effect and records of cases where the damage cannot be reversed.
when analyzing people who have no hearing at all they can be split into two main categories, those that have had their hearing deteriorate after learning basic language skills and those who went deaf beforehand. Those who never had the chance to learn basic language skills are often at a loss in later life as they may possibly be restricted to using sign language as the means of hearing a language to learn it has been removed.
Though deafness in babies can be brought on by disease, illness and in rare cases inherited from their genetics it is often not noticed until later stages of development. With the amount of people suffering from deafness due to genetic disorders being so low it is a shame that deaf children are regularly born into families that have no experience of conversing with people who are deaf.
A loss of some hearing will not necessarily impair some body
