人类的听力对正常耳朵中从20赫兹到20,000赫兹的声音很敏感。然而，人类听力的临床测试很少包括扩展高频(EHF)阈值评估，频率超过8,000赫兹。流行性出血热阈值被建议用于监测噪声对内耳的最早影响，尽管流行性出血热阈值测试的临床实用性并不是很好地确定用于这一目的。这项研究的主要目的是确定健康的年轻成年大学生的流行性出血热阈值是否随着娱乐性噪音暴露而变化。对实验室数据库进行了回溯性分析；所有参与者都有流行性出血热阈值测试和噪声历史数据。根据测量的阈值评估“临床前”流行性出血热缺陷的可能性，并使用噪声调查来估计娱乐性噪声暴露。在参与其他正在进行的研究期间测量的流行性出血热阈值来自87名受试者(34名男性和53名女性)；所有参与者在常规频率(0.25至8千赫)下的听力都在正常的临床极限(≤25HL)内。流行性出血热阈值与标准参考阈值非常接近[附件C]。在使用音乐播放器的受试者中，存在统计上可靠的阈值差异，在报告长期使用音乐播放器设备(超过5年)的参与者中，在最高测试频率(10-16 kHz)下的阈值差3-6分贝，或者在使用音乐播放器期间更高的收听水平。对于定期接受重复测试的患者/参与者，应该可以检测到高频听力的微小变化。然而，最高频率的阈值在人群水平上的变异性增加，将使人们很难在没有先前建立的基线数据的其他正常听力个体中识别是否存在微小但潜在重要的缺陷。
Human hearing is sensitive to sounds from as low as 20 Hz to as high as 20,000 Hz in normal ears. However, clinical tests of human hearing rarely include extended high frequency (EHF) threshold assessments, at frequencies extending beyond 8,000 Hz. EHF thresholds have been suggested for use monitoring the earliest effects of noise on the inner ear, although the clinical utility of EHF threshold testing is not well established for this purpose. The primary objective of this study was to determine if EHF thresholds in healthy, young adult college students vary as a function of recreational noise exposure. A retrospective analysis of a laboratory database was conducted; all participants with both EHF threshold testing and noise history data were included. The potential for “pre-clinical” EHF deficits was assessed based on the measured thresholds, with the noise surveys used to estimate recreational noise exposure. EHF thresholds measured during participation in other ongoing studies were available from 87 subjects (34 male and 53 female); all participants had hearing within normal clinical limits (≤25 HL) at conventional frequencies (0.25 to 8 kHz). EHF thresholds closely matched standard reference thresholds [ Annex C]. There were statistically reliable threshold differences in subjects that used music players, with 3–6 dB worse thresholds at the highest test frequencies (10–16 kHz) in participants that reported long-term music player device use (longer than 5 years), or higher listening levels during music player use. It should be possible to detect small changes in high frequency hearing for patients/participants that undergo repeat testing at periodic intervals. However, the increased population-level variability in thresholds at the highest frequencies will make it difficult to identify the presence of small but potentially important deficits in otherwise normal hearing individuals that do not have previously established baseline data.
