Types of hearing impairment

In addition to the words mentioned above, some specialists have separated impairment into the following two sub-groups:

Pre-lingual Deaf: “The term “pre-lingual Deaf” refers to a youngster who has little or no hearing at birth. His hearing impairment is obvious before he learns speech and language patterns.

Post-lingual Deaf: A “A post-lingually deaf child is one that develops hearing loss as a result of external factors. Once he has developed a speech and language pattern, his hearing handicap becomes apparent.

Recently a group of experts sub-divided the hearing impaired people into the following categories:

Conductive Hearing Loss: Among children with hearing problems, conductive losses are typical. These have the effect of making the sound less loud. The middle ear pathological alterations brought on by congenital or acquired ear disorders may be the primary cause. Even if they are little, they can still be treated surgically or medically. The likelihood of hearing impairments may frequently be significantly reduced by preventing chronic ear infections.

Sensori-neural Hearing Loss: Hearing loss can occasionally be brought on by issues with the auditory nerve or the inner ear. But surgical treatment is rarely effective in curing it. The use of hearing aids for sound amplification is not directly related to this problem. Here the sound is conducted adequately and the challenge arises in evaluating or detecting it appropriately. For youngsters with this condition, the only kind of therapy that can be used is schooling. Children with mild disabilities could benefit from language, lip-reading, auditory training, and hearing aids. However, children with severe hearing loss can require specialised instruction.
Psychogenic Hearing Loss: In this instance, the disorder’s root cause is entirely psychological. The youngster exhibits severely exaggerated signs of hearing loss. The localization of the mental symptom may be caused by an ear infection. The youngster may occasionally unintentionally lose his hearing as a means of escaping what, in his eyes, is an unpleasant circumstance. It becomes challenging to discriminate between biological flaws and psychogenic losses, nevertheless. Only the right audiological procedures used in conjunction with thorough observation can aid in making an accurate diagnosis.
Central Auditory Defects: These kinds of problems are quite complicated, and it is unclear what causes them or how they develop. These kids appear to be hearing sound, but they are unable to distinguish its meaning. Significant communication issues result from this. Early infancy appears to have a very high prevalence of these abnormalities. Again, certain medicines that can save lives also seem to have an impact on the auditory system. Such youngsters are exceedingly challenging to treat since they need intensive, protracted individual therapy.
