Sensorineural hearing loss occurs when there is damage to the inner ear or the pathways from the inner ear to the brain. It is the most common form of permanent hearing loss, and typically cannot be repaired. Most sensorineural hearing loss is due to damaged hair cells in the inner ear, and this can be present at birth or acquired during the lifetime of the individual. Symptoms of sensorineural hearing loss include delayed development of speech or unclear speech, use of high volume on electronic viewing devices, and consistent need to ask for repitition in conversation. Treatment may include hearing aides or cochlear implants to improve hearing ability.
