- Pathophysiology
- Slowly progressive Sensorineural Hearing Loss
- Typically due to atrophy of Organ of Corti and auditory nerve at basal end of Cochlea
- Multifactorial from aging, genetic predisposition, vascular supply to the Cochlea and other risk factors (see above)

- Decreased speech discrimination
- See Hearing Impairment Severity Scale
- Poor understanding of speech even when loud enough
- Recruitment
- Abnormal Hypersensitivity to noise
- Evaluation
- Audiometry displays high pitched Hearing Loss
- Acoustic reflex testing
- Management
