目标：提供未经筛查的老年人的听力阈值百分位数，以创建新的附件 B 参考标准。设计：计算百分位数，并以图形方式比较美国两项调查中位数的 95% 置信区间。结果：1999-2006 年国家健康和营养检查调查中，除 1 kHz 之外的所有频率的男性的中位数阈值较低（较好）。女性的结果相似；然而，不同频率的置信区间有更多重叠。结论：1999-2006 年，70 岁（65-74 岁）老年人的听力障碍患病率低于 19591962 年，这与我们早期对年轻人的研究结果一致。
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 19591962, consistent with our earlier findings for younger adults.
