Download Types of hearing impairment

A hearing impairment signifies a
full or partial loss of the ability to
detect or discriminate sounds
OR
A person who cannot hear at or
about a certain intensity is
termed as hearing impairment
•Organic Hearing Loss
•Sudden Hearing Loss
•Hereditary Hearing Loss •Progressive Hearing Loss
•Congenital Hearing Loss •Conductive Hearing Loss
•Acquired Hearing Loss
•Pre Lingual Hearing Loss
•Sensori Neural Hearing Loss
•Mixed Hearing loss
•Post Lingual Hearing Loss
The term organic hearing loss
Defect in auditory system resulting
in organic hearing loss (that may be in
external ear, middle ear or in the
auditory nerve)
The hearing loss caused by
factors present in the genetic
make up of the fertilized
ovum
•Congenital hearing loss means the
condition of hearing loss existing since
birth
•Congenital hearing loss may be
hereditary or may develop during
prenatal or natal period
The term indicated that the hearing
mechanism was normal at one time
and hearing loss developed at a later
stage due to some reason like sever
illness, accidents etc.
•The term per-lingual indicates that
hearing loss developed prior to the
language learning age.
•The hearing loss developed during the
first three years of life is considered as
pre lingual hearing loss
•The term post lingual hearing loss
indicate that the hearing loss
developed after the language had
developed.
•Post lingual hearing loss can be
sudden or progressive in nature
•Sudden hearing loss results due to
one time insult to the auditory
system.
•The damage to the auditory
system results as a permanent
hearing loss
•Hearing loss is getting worse with time.
•This may be due to the infection or
hereditary disorder
•The disorder of hearing can result
from defects of diseases in outer middle
or inner ear or auditory nerve
•Any dysfunction of the outer or middle ear in
the presence or a normal inner ear is termed as
conductive impairment.
•The acquired hearing losses in children are
more likely to be of the conductive type.
•The conductive hearing loss can be congenital
(i.e. loss existing since birth)or acquired due to
some reason(i.e. illness, accident)
•When the loss of hearing function is
due to pathology in the inner ear or
along the nerve pathway from the
inner ear to the brain stem. The this
loss is referred as sensori neural
impairment.
Is the combination of both
conductive hearing loss and
sensori neural hearing loss
