Hearing disorder
Hearing Disorder
Hearing disorder (pronunciation: /ˈhɪərɪŋ dɪsˈɔːdər/) is a broad term used to describe a variety of conditions that affect the normal functionality of the ear and the ability to perceive sound.
Etymology
The term "hearing disorder" is derived from the English words "hearing" (from Old English 'hieran', meaning to hear) and "disorder" (from Latin 'dis-', meaning apart, and 'ordo', meaning order). Thus, it refers to a condition that disrupts the normal order or function of hearing.
Types of Hearing Disorders
There are several types of hearing disorders, including:
- Conductive hearing loss: This occurs when there's a problem conducting sound waves anywhere along the route through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles).
- Sensorineural hearing loss: This type of hearing loss, also known as nerve deafness, is caused by damage to the inner ear or the nerve from the ear to the brain.
- Mixed hearing loss: This is a combination of conductive and sensorineural hearing loss.
- Auditory processing disorder: This is a condition that affects the way the brain processes auditory information.
Diagnosis
Diagnosis of a hearing disorder typically involves a comprehensive audiological evaluation, which may include a hearing test, tympanometry, and other diagnostic procedures.
Treatment
Treatment for hearing disorders depends on the specific type and cause of the hearing disorder, but may include hearing aids, cochlear implants, or surgery. In some cases, speech therapy or audiology rehabilitation may also be recommended.
