National Health and Nutrition Examination Survey II, 1976-1980: Audiometric Air Conduction Test, Ages 4-19 Years

The NHANES II Audiometric Air Conduction Test data file contains two parts of the extensive data available from NHANES II: demographic information obtained during the household interview, and audiometric test data on hearing thresholds of persons ages 4-19 years in the sample households. The demographic data include information on the type of residence and housing, composition of the household, vehicles, languages spoken, income sources and amounts, food stamps and commodity foods, employment, age, race and national ancestry, sex, education, marital status, veteran status, and region of country. The audiometric data were obtained at the following four frequencies: 500, 1000, 2000, and 4000 Hertz (Hz). Hearing levels were reported as the decibel level of pure tone just audible to the ear of the examinee. There are also data on any conditions such as earache, cold, or equipment defect that might affect the test results.
