Abstract

Numerous studies have suggested that noise exposure might be associated with changes in stress hormone levels. However, quantitative evidence for these effects in humans is rare and remains controversial. This study aimed to investigate the acute effects of exposure to noise and its different levels on stress hormone changes in task performance. Quasi-experimental noise exposure environment was established for 90 male university student volunteers in their twenties, and each was exposed to different noise levels during task performance. The stress hormones tested included cortisol, adrenocorticotropic hormone (ACTH), adrenaline, and noradrenaline. A one-way ANOVA was performed to investigate differences in hormone levels measured in the three groups according to the noise exposure levels (35, 45, or 75 dB). Analysis of covariance (ANCOVA) was used to adjust for confounding factors that might affect hormone levels. After adjusting for confounders, significant exposure-dependent differences were found in hormone levels in salivary cortisol, serum cortisol, serum ACTH, and serum adrenaline. The amount of hormonal increase in 75 dB exposure group compared to 35 or 45 dB groups was detected. Similar results were also seen in the rate of change analysis. Our findings indicate that short-term noise exposure during task performance elevates stress hormone levels. Further, the extent of stress hormone alterations varies with noise exposure levels. Changes in hormone levels are an objective measure that may be used to identify health effects and stress responses in various noise environments.

噪音暴露对韩国年轻男性任务执行过程中应激激素变化的影响:准实验研究。
大量研究表明,噪声暴露可能与应激激素水平的变化有关。然而,这些影响在人体中的定量证据并不多见,而且仍存在争议。本研究旨在调查暴露于噪声及其不同水平对任务表现中应激激素变化的急性影响。研究人员为 90 名 20 多岁的男性大学生志愿者建立了准实验噪音暴露环境,让他们在完成任务时分别暴露在不同的噪音水平下。测试的应激激素包括皮质醇、促肾上腺皮质激素(ACTH)、肾上腺素和去甲肾上腺素。研究人员根据噪音暴露水平(35、45 或 75 dB)对三组中测得的激素水平进行了单因素方差分析。方差分析(ANCOVA)用于调整可能影响激素水平的混杂因素。在对混杂因素进行调整后,发现唾液皮质醇、血清皮质醇、血清促肾上腺皮质激素和血清肾上腺素的激素水平与暴露水平存在显著差异。与 35 分贝或 45 分贝组相比,75 分贝暴露组的激素增加量更大。在变化率分析中也发现了类似的结果。我们的研究结果表明,在执行任务过程中暴露于短期噪音会提高应激激素水平。此外,应激激素的变化程度随噪音暴露水平的不同而变化。激素水平的变化是一种客观的测量指标,可用于确定各种噪声环境对健康的影响和应激反应。
