Objectives: To provide hearing threshold percentiles from unscreened older adults for creating new Annex B reference standards. Design: Percentiles are calculated, and 95% confidence intervals for medians from two U.S. surveys are compared graphically. Results: Median thresholds are lower (better) in the 1999-2006 National Health and Nutrition Examination Survey for men across all frequencies except 1 kHz. Results for women are similar; however, there is more overlap in confidence intervals across frequencies. Conclusions: The prevalence of hearing impairment in older adults, age 70 years (65-74 years), is lower in 1999-2006 compared with 1959-1962, consistent with our earlier findings for younger adults.
