Table 2. Percent correct classification and misclassification bias of objective hearing loss compared to self-reported hearing loss.^a.

These analyses are further stratified by gender, age group, race/ethnicity, and education. Objective hearing impairment was defined as at least speech PTA > 25 dB in the better-hearing ear and subjective hearing impairment was defined as a little trouble/ moderate trouble/ a lot of trouble hearing/ deaf.

^aSampling weights were not used in these calculations.

^bChi-squared tests for general association were used to compare percent correct classification by gender, age group, race/ethnicity, education, and sub-analyses. Chi-squared tests for general association were used to compare misclassification bias by gender, age group, race/ethnicity and education. The Mantel-Haenszel chi-square test was used to test age group trends in the sub-analyses.

^cHS – high school education

^dAA degree – Associate’s degree
