What is Hearing Impairment & Deafness?

Hearing impairment is "an impairment in hearing, whether permanent or fluctuating, that adversely affects a child’s educational performance. Deafness is a hearing impairment that is so severe that the child is impaired in processing linguistic information through hearing, with or without amplification” (IDEA, 2020). 

There are four types hearing loss:

  • Sensorineural:

    • Caused by issues with the inner ear and auditory nerve.​

  • Conductive:

    • Caused by an issue with the outer or middle ear, usually some type of blockage.

  • Mixed:

    • Describes a mixture of sensorineural and conductive hearing loss.​

  • Central:

    • Caused by a disorder of the nervous system and the brain.​

  • Reluctance to interact with their peers because of communication issues related to hearing impairment.

  • There may be a deficit in maturity and social acuity because of reduced social interaction opportunities.

Social 
Academic
  • Difficulty with language acquisition.

  • Difficulty or inability to receive information through verbal speech, depending on severity level of impairment.

  • Academic achievement is typically below hearing peers.

  • Higher academic achievement in mainstream vs. self-contained classrooms. 

Cognitive
Physical
  • Impairment of the outer, middle or inner ear. 

  • May wear hearing aids or have a cochlear implant.

Affective
  • May become easily frustrated
    •    Reluctant to lead in social situations
    •    Can be embarrassed by the need for hearing aids or other supports.
    May become easily frustrated.

  • May be reluctant to lead in social situations.

  • Can be embarrassed by the need for hearing aids or other supports.
     

  • A difference in cognitive functioning is not associated with hearing impairment.

  • Intellectual development can be negatively impacted by any difficulties  associated with language acquisition.

Levels of Severity
  • Hearing impairment ranges from  mild, moderate, severe, or profound.

  • The severity level depends upon how well a person can hear the intensities or frequencies associated with speech.

  • Impairments in hearing can occur in either or both areas, and may exist in only one ear or in both ears.

  • Deafness describes a hearing loss is greater than 90 decibels (dB).

Strengths
  • Adaptable

  • Detail oriented

  • Very visual

  • Excels at reading              non-verbal cues

Incidence

  • It is estimated that 12,000 babies are born each year with a hearing impairment.

Educational
Implications
  • Around 40% of students with a hearing impairment are in a mainstreamed classroom.

  • Students with hearing impairment may have issues hearing in a noisy setting.

  • Assistive technologies, like hearing aids and amplification devices, need to be utilized to optimize learning.

  • Teachers should always face hearing impaired and deaf students while speaking, because lip reading and body language cues augment their spoken language comprehension.

Student Questions
