This study was conducted to compare the pattern of age-related hearing decline in individuals with and without self-reported previous occupational noise exposure. This was a prospective, population-based, longitudinal study of individuals aged 70-75 years, from an epidemiological investigation, comprising three age cohorts. In total there were 1013 subjects (432 men and 581 women). Participants were tested with pure tone audiometry, and they answered a questionnaire to provide information regarding number of years of occupational noise exposure. There were no significant differences in hearing decline, at any frequency, for those aged 70-75 years between the noise-exposed (N= 62 men, 22 women) and the nonexposed groups (N = 96 men, 158 women). This study supports the additive model of noise-induced hearing loss (NIHL) and age-related hearing loss (ARHL). The concept of different patterns of hearing decline between persons exposed and not exposed to noise could not be verified.
本研究旨在比较有和没有自我报告既往职业噪声暴露史的个体中与年龄相关的听力下降模式。这是一项基于人群的前瞻性纵向研究，研究对象为来自一项流行病学调查的70 - 75岁个体，包括三个年龄队列。总共有1013名受试者（432名男性和581名女性）。参与者接受了纯音听力测试，并回答了一份问卷，以提供有关职业噪声暴露年限的信息。在70 - 75岁的人群中，有噪声暴露史组（N = 62名男性，22名女性）和无噪声暴露史组（N = 96名男性，158名女性）在任何频率下的听力下降均无显著差异。本研究支持噪声性听力损失（NIHL）和年龄相关性听力损失（ARHL）的累加模型。暴露于噪声和未暴露于噪声的个体之间听力下降模式不同的概念无法得到验证。
