噪声性听力损失（NIHL）是一种不可逆的疾病，是工业环境中的常见问题。NIHL的早期诊断有助于防止听力损失的进展，特别是在语音频率方面。对于NIHL的早期诊断，常规频率进行听力测定。本研究旨在比较噪声对高频测听（HFA）和常规测听的影响。在一项历史性队列研究中，我们比较了纺织工人在常规和高频听力测定中的听阈和听力损失患病率，这些工人被分为两组：有和没有暴露于超过85 dB的噪声中。常规右耳测听、常规左耳测听和HFA分别在4000 Hz、6000 Hz和16000 Hz观察到最高听阈。与4000 Hz相比，16000 Hz时的听阈明显更高。听力损失在HFA中比常规测听更常见。HFA检测NIHL的敏感性高于常规测听。它可以用于早期诊断对噪声的听力敏感性，从而防止低频尤其是语音频率的听力损失。
Noise-induced hearing loss (NIHL), an irreversible disorder, is a common problem in industrial settings. Early diagnosis of NIHL can help prevent the progression of hearing loss, especially in speech frequencies. For early diagnosis of NIHL, audiometry is performed routinely in conventional frequencies. We designed this study to compare the effect of noise on high-frequency audiometry (HFA) and conventional audiometry. In a historical cohort study, we compared hearing threshold and prevalence of hearing loss in conventional and high frequencies of audiometry among textile workers divided into two groups: With and without exposure to noise more than 85 dB. The highest hearing threshold was observed at 4000 Hz, 6000 Hz and 16000 Hz in conventional right ear audiometry, conventional left ear audiometry and HFA in each ear, respectively. The hearing threshold was significantly higher at 16000 Hz compared to 4000. Hearing loss was more common in HFA than conventional audiometry. HFA is more sensitive to detect NIHL than conventional audiometry. It can be useful for early diagnosis of hearing sensitivity to noise, and thus preventing hearing loss in lower frequencies especially speech frequencies.
