TYPES OF HEARING LOSS

PART 2

Sensorineural Hearing Loss occurs when there is damage to the inner ear (cochlea) or to the nerve pathways from the inner ear to the brain. Sensorineural hearing loss usually is not medically or surgically correctable and often a permanent loss.

Sensorineural hearing loss not only involves a reduction in volume, but also affects speech understanding, the ability to hear clearly.

Sensorineural hearing loss can be caused by diseases, birth injury, drugs that are toxic to the auditory system, and genetics. Sensorineural hearing loss may also occur as a result of noise exposure, viruses, head trauma, aging, and tumors.
