Presbycusis is the loss of hearing that gradually occurs in most individuals as they grow older. This is usually a __________ hearing disorder
1. Sensorineural
2. Conductive
3. Mixed
4. Air conduction
Sensorineural
Rationale: Presbycusis is usually a sensorineural hearing disorder caused by gradual changes in the inner ear as a result of loss of hair cells in the organ of Corti. There can be conductive causes of hearing loss, but sensorineural disorders are more common. There could also be mixed causes of hearing loss, but these are not as common as sensorineural. Interference of air conduction is not the result of aging.
