The 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:

the subjects of grammar, spelling and vocabulary
taking notes while listening to lectures
participating in classroom discussions
watching educational videos
presenting oral reports

Underscoring the difficulty that students with hearing impairments may have in presenting oral reports are the potential language development problems linked to hearing impairments. Arizona’s Department of Education’s Parent Information Network notes that, “Since children with hearing impairments are unable to receive some sounds accurately, they often cannot articulate words clearly.”
