Hearing aids are miniscule electronic devices used for amplifying sound and also processing it. A hearing aid consists of a processor that is used to process and amplify sound, a microphone either one or two used to pick up the sound, a battery for power source and a speaker that is used to send a signal into the ear. Hearing aid comes in various styles and types and there are a number of factors you should consider before purchasing one. Some of these factors include fitting, cleaning, repair, reviews, price, style, type and accessories.
The main function of hearing aid is to help patients with hearing problems or healing loss to be able to hear in a better way. Hearing loss is caused by many causes where some are treatable and other are not. Here are some of the common hearing problems and how hearing aid devices can help.
Conductive hearing loss
This type of hearing problem is brought about by a problem in the middle ear, canal or ear drum. Conductive hearing loss include malformation, failure of ear canal to open during birth, congenital absence or dysfunction in the middle ear. All these problems can be solved through surgical correction but sometimes it is not successful. In that case, a hearing alternative is improved by implanting a hearing aid or using a bone conducting hearing aid or a conventional hearing aid.
Sensorineural hearing loss
This hearing loss is brought about by problems in the inner ear which are also referred to as nerve-related hearing loss. Most of the complications in sensorineural hearing loss are reversible like those from fluctuating, traumas, sudden sensorineural hearing loss and bilateral progressive. However some of these hearing problems are not treatable and one will require administration of hearing aid.
Mixed hearing loss
This refers to a permutation of sensorineural and conducted hearing loss. In other words this is to mean a lot of damage has occurred in the inner and middle ear. It can be a complicated situation but with hearing device such as Oticon Agile pro mini rite it can be made simpler.
