II. Epidemiology
- Hearing declines by 1 dB per year after age 60
 - Incidence Hearing Loss of 25 dB or more
- Age 60 to 70 years: 37%
 - Age 71 to 80 years: 60%
 - Age over 85 years: 80%

                          Sensorineural Hearing Loss
                          
- Immediately evaluate Sudden Hearing Loss
 - Audiology evaluation for Assistive Devices
 
 - 
                          Conductive Hearing Loss
                          
- Cerumen Impaction is most common (30% of cases)
 - 
                              Chronic Serous Otitis Media
