Purpose

This study aimed to determine hearing thresholds in an otologically normal population without occupational noise exposure aged 18 to 64 years using extended high-frequency audiometry (EHFA).

Methods

Individuals from the general population who have never had hearing problems and whose job was not associated with noise exposure were included in the study and classified by age into 5 categories: 18–24 and, further, by 10 years of age. Each of these groups was further divided according to gender. All subjects underwent tympanometry, conventional pure-tone audiometry within the 0.125–8 kHz range, and extended high-frequency audiometry within the 9–16 kHz range, performed according to the standards. The significance level for statistical testing was set at 5%.

Results

Here, we established hearing thresholds in an otologically healthy population within the extended high-frequency (EHF) range (9–16 kHz). We found the EHFA to be a highly sensitive method for early detection of hearing loss, with hearing thresholds decreasing as soon as 35 years of age. In males, the hearing thresholds grew with age more rapidly than in women. The ability to respond at EHF gradually decreased with age and increasing frequency.

Conclusion

Our results can help improve the knowledge of EHF hearing thresholds for individual sexes and age groups. So far, the standard 7029:2017 is not binding and, moreover, it only reaches up to the frequency of 12.5 kHz. EHFA is a highly sensitive method for the evaluation of hearing loss depending on age and sex.

扩展高频测听：成人听力阈值

目的

本研究旨在使用扩展高频测听 (EHFA) 确定 18 至 64 岁、无职业噪声暴露的耳科正常人群的听力阈值。

方法

研究纳入了从未有过听力问题且工作与噪声暴露无关的普通人群，并按年龄分为 5 类：18-24 岁，以及 10 岁。每个组都根据性别进一步划分。所有受试者均按照标准进行了鼓室导抗测试、0.125-8 kHz 范围内的传统纯音测听以及 9-16 kHz 范围内的扩展高频测听。统计检验的显着性水平设定为5%。
