Key facts
- PhenX - audiogram hearing test protocol 200101
- The National Health and Nutrition Examination Survey (NHANES) 2008-2009 audiometry protocol tests the examinee's hearing threshold (in decibels, dB) at 7 frequencies in a soundproof room. Examinees are asked a series of exclusionary questions, undergo an outer-ear examination (otoscopy), and then have the mobility of their eardrum tested (acoustic immittance). Pure tone signals are then presented to each ear through earphones and the intensity of the signals is varied until the level is identified at which the person is just able to hear the sound. An audiogram should be conducted in a soundproof room or booth to permit accurate hearing threshold measurements. Although the 2009-2010 National Health and Nutrition Examination Survey (NHANES) conducts pure tone audiometry on individuals ages 12-19 years and older than 70 years, previous versions of the National Health and Nutrition Examination Survey have performed this procedure on children as young as 4 years and adults of all ages.
