目的：本研究的目的是（1）重新计算国际标准ISO 7029：2017中描述的纯音听阈水平（HTLs），以及（2）解释标准中HTLs的推导过程。设计：将用于制定ISO 7029：2017的纯音听阈数据和其他数据集结合起来，重新估计HTLs中位数和中位数周围的单个HTLs分布。计算是针对年龄从18岁到80岁的125 Hz到8000 Hz的听力频率和从9000 Hz到12，500 Hz的扩展高频进行的。研究样本：在9个国家的15项研究中雇用了大约9，000名男性和20，000名女性。他们进行了严格的筛选听力abnormal.Results：一组新的中位数HTLs和分布周围的中位数分别获得作为男性和女性的年龄的函数，并与ISO 7029中的估计。结论：所描述的计算过程将有助于理解ISO 7029：2017中的标准HTL是如何获得的。重新计算的HTL可以作为下一版标准的基础，涵盖更广泛的人群。
Objective: The objectives of this study were (1) to re-calculate hearing threshold levels (HTLs) for pure tones as described in an international standard, ISO 7029:2017, and (2) to explain the procedure of how HTLs in the standard had been derived.Design: Pure-tone hearing threshold data used for developing ISO 7029:2017 and additional data sets were combined to re-estimate median HTLs and the distribution of individual HTLs around the median. The calculation was done for audiometric frequencies from 125 Hz to 8000 Hz and extended high frequencies from 9000 Hz to 12,500 Hz for ages from 18 to 80 years.Study sample: Approximately 9000 men and 20,000 women employed in 15 studies in nine countries. They had been rigorously screened for hearing abnormalities.Results: A new set of median HTLs and distribution around the median was obtained as a function of age for males and females separately and compared with the estimates in ISO 7029. The differences among these threshold values were discussed.Conclusions: The calculation procedure described would help understand how the normative HTLs in ISO 7029:2017 had been obtained. Re-calculated HTLs could serve as a basis for the next edition of the standard that covers a wider range of population.
