QUESTION 2The four major types of hearing loss that are categorized by the site of the disorder in the auditory system are: a. genetic or hereditary factors, infections, developmental abnormalities, or environmental/traumatic factors b. omissions, substitutions, distortions and stuttering c. conductive, sensorineural, mixed hearing loss and central hearing disorders d. loudness, intensity, frequency, pitch
Solution
The correct answer is c. conductive, sensorineural, mixed hearing loss and central hearing disorders. These are the four major types of hearing loss categorized by the site of the disorder in the auditory system.
-
Conductive hearing loss: This type of hearing loss is due to problems with the ear canal, ear drum, or middle ear and its little bones (the malleus, incus, and stapes).
-
Sensorineural hearing loss (SNHL): This type of hearing loss occurs when there is damage to the inner ear (cochlea), or to the nerve pathways from the inner ear to the brain.
-
Mixed hearing loss: This is a type of hearing loss that includes both conductive and sensorineural hearing loss. It means that there may be damage in the outer or middle ear and in the inner ear (cochlea) or auditory nerve.
-
Central hearing disorders: These disorders occur when the central nervous system has trouble processing the sounds that the ears hear. People with central hearing disorders have a hard time understanding or interpreting sounds, even though their hearing may be normal.
