本研究目的是探討在噪音環境下工作對於情緒之影響，過去的一些研究發現噪音不僅會造成聽力損失，也會引起情緒緊張、血壓升高、及失眠等症狀。對於長時間處於噪音工作場所的員工，職場上的噪音對於身體情緒的影響是值得探究的。此研究乃針對台灣北部某間歸類於噪音作業(工作環境噪音大於85dB)之石化工廠的232位員工，以台灣人憂鬱症量表[1]來做分析。本研究於2010年1月針對該工廠之232位員工發出台灣人憂鬱症量表之問卷，回收問卷共138份、有效問卷137份。分析結果發現其中得分大於等於19分以上之可能患有憂鬱症者佔有9%；而得分小於等於8分之情緒穩定者佔有58%。此研究之結果明顯高於另一於2005年於台灣社區所作之憂鬱症比率3.7%[2]，顯示出長期在噪音環境下工作的人，其精神心理狀態有較高的比率呈現不穩定狀態，這也是職場工作安全所必須重視的。
