噪音暴露對非聽覺影響之研究

研究目的本研究探討在職場環境中存在之噪音，對於作業勞工在非聽力損失部分的生理以及心理上造成之影響，藉由研究結果瞭解噪音音壓位準、頻率、與變動性等特性，對暴露者之生心理之影響情形。研究方法於實驗室針對噪音暴露之受測者，利用生理量測系統（心搏率、血壓）、心理負荷測驗以及主觀問卷等方法，評估受測者在噪音環境下，其生心理變化情況。研究結果與討論當受測者暴露噪音一段時間後，其生心理情況產生變化，在生理方面，結果顯示噪音的變動性會對生理產生影響，而音壓位準與頻率的交互作用也會造成部分影響；在心理方面，結果顯示噪音的頻率類型會對受測者的注意力造成影響，結論對於從事噪音作業的勞工及管理者，本研究成果可提供作業場所的噪音環境改善參考，以提升作業環境品質與促進作業效率。

Objective The study is to investigate on non-auditory (physiological and psychological) effects for workers due to noise exposure in occupational environment. Through study results, it is supposed to understand how sound pressure level, frequency, and variability and other characteristics of noise to influence physiological/psychological conditions of the exposed persons.Research Methods The subjects were exposed to noise in laboratory to evaluate their physiological/psychological variation by using physiological measurement system (i.e. heart rate, blood pressure), psychological load tests, subjective questionnaires and etc.Results and Discussion When the subjects were exposed to noise for a period of time, a variation was observed both on their physiological and psychological aspects. The results showed that the noise variability could affect physiological responses, the interaction of sound pressure level and frequency could also cause some of the impact on physiological aspects, while the types of noise frequency might affect subjects’ attention.Conclusion For workers and managers in noisy workplace, the results of this study may provide as a reference for workplace improvement to enhance the quality of the working environment and promote operational efficiency.
