Hearing Impairment (Strategies and Accommodations for working with Hearing…
- defined by the degree of loss, type of loss, and the age at which the loss occurred
- defined as a hearing impairment that is severe enough
- that the child cannot process linguistic information through hearing
- even when using amplification or hearing aids.
- can be inherited from one or both parents; can be present at birth or develop later (congenital hearing loss)
- 30-40% of children with hearing loss have other associated disabilities.
- includes exposure to:
- trauma/ injury
- infection during the course of pregnancy/ birth process (TORCHS)
- most common cause is: otitis media.
Maternal infections (TORCHS)
TO: Toxoplasmosis (a parasitic diesease)
R: Rubella ( German measles)
C: Cytomegalovirus [ CMV] ( An infection in the mother's uterus which can go undiagnosed)
HS: Herpes ( causes neurological problems as well as deafness)
Age of Onset of Hearing Loss
can be either congenital or acquired.
- congenital: present at birth
- acquired: occurred in either childhood or adulthood
Prelinguistic hearing loss
- a hearing loss that occurs before the child's language has developed.
- a hearing loss that occurs after child has acquired some speech and language.
Degree/ Level of Hearing loss
- The severity of hearing loss
- is determined by the individual's reception of sound
- measured in decibels (dB)
- poor articulation of sounds when speaking
- extremely high volume when listening to audio materials
- cocking/ turning the head to hear better
- unresponsive or inattentive to normal voice
often requesting for audio information to be repeated
