To provide hearing threshold percentiles from unscreened older adults for creating new Annex B reference standards.
Percentiles are calculated, and 95% confidence intervals for medians from two U.S. surveys are compared graphically.
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.
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.
为制定新的 Annex B 参考标准，提供未经筛查的老年人群的听力阈值百分位值。
计算百分位值，并对来自两项美国调查的中位数的 95%置信区间进行图形比较。
除 1 kHz 外，1999-2006 年全国健康与营养调查（NHANES）男性所有频率的听力阈值中位数均较低（更好）。女性的结果相似；然而，各频率之间的置信区间重叠更多。
与 1959-1962 年相比，1999-2006 年 70 岁（65-74 岁）老年人群的听力障碍患病率更低，这与我们之前对年轻人群的研究结果一致。
