HEARING IMPAIRMENT
DefinitionHearing impairment as a disability category is similar to the category of deafness, but it is not the same. The official definition of a hearing impairment by the Individuals with Disabilities Education Act (IDEA) is “an impairment in hearing, whether permanent or fluctuating, that adversely affects a child’s educational performance but is not included under the definition of ‘deafness.'” Thus, knowing the definition of deafness is necessary to understand what sort of disabilities are considered hearing impairments. A hearing loss above 90 decibels is generally considered deafness, which means that a hearing loss below 90 decibels is classified as a hearing impairment.
Primary Characteristicshe National Dissemination Center for Children with Disabilities (NICHCY) explains that hearing loss falls into four subcategories: conductive, sensorineural, mixed and central. These identify the location in the body in which the hearing impairment occurs. Hearing aids and other sound amplifying assistive technologies (AT) often work for students with conductive hearing loss, as their impairments stem from the outer or middle ear. Such does not hold true with sensorineural, mixed and central hearing losses, as these impairments stem from the inner ear, the central nervous system or a combination of the two. Typically, hearing loss is categorized as slight, mild, moderate, severe or profound, depending on how well an individual can hear the frequencies that are commonly associated with speech.
Educational Challenges Educational obstacles related to hearing impairments stem around communication. A student with a hearing impairment may experience difficulty in:
