Abstract:	噪音暴露導致的聽力損失，已經是一個全球性的問題，在現今社會噪音也被列為是其中一項嚴重公害，除了平時儘量減少在高噪音場所活動來保護聽力外，當工作環境充斥噪音時，企業雇主應提供良好的防護措施，以保障員工健康。本研究以玻璃纖維相關製品工廠做為研究對象，針對噪音區域作業人員進行調查，以作業環境監測報告、歷年體檢資料與問卷三方面進行調查及分析，以了解玻璃纖維工廠噪音暴露實況。研究結果顯示，全廠在噪音作業區工作的員工大部分皆以達到輕度聽力損失的程度，尤其以編織課的聽損失最為嚴重，已經有40 dB的聽力損失情形。彙整各噪音作業區分析結果後得到以下幾個結論： 1.暴露在噪音作業場所時間越長，接收到的暴露劑量越多，風險越大。 2.防音防護具配戴與否，確實會影響聽力損失的情況及嚴重度。 3.血壓與噪音暴露無直接明確的關係。 4.教育訓練的實施，與員工對危害認知有一定程度的關係。未來建議尋找新的機械設備進行替換，改善機械設備因老舊造成的異音，若無法進行設備更換，建議設置隔音牆、隔音棉等加強製程隔音，才能有效將人員暴露降到最低，進而保障員工健康，達到永續經營的目的。;Hearing loss caused by noise exposure has been a global problemand become one of the public severe hazards. In addition to minimizing activities in high-noise places to protect hearing, when the working environment is full of noise, business employers should provide reasonable protective measures to protect employees′ health. This study focused on a glass fiber-related product factory and investigated the noise exposure of workers in designated noisy areas. It involved conducting surveys and analyses based on operational environmental monitoring reports, historical physical examination data over the years, and questionnaires. The aim is to understand the actual situation of noise exposure in the fiberglass factory. The research results showed that most of the employees working in the noisy work area of the factory have achieved mild hearing loss, especially in the knitting class, where the hearing loss is the most serious, with a hearing loss of 40 dB. After collecting the analysis results of each noise operation area, the following conclusions are drawn: 1. The longer the exposure time in the noisy workplace, the greater the exposure dose received and the greater the risk. 2. Whether the soundproof protective gear is worn or not will indeed affect the condition and severity of hearing loss. 3. There is no direct and clear relationship between blood pressure and noise exposure. 4. The implementation of education and training has a certain degree of relationship with employees′ perception of hazards. In the future, it is recommended to find new mechanical equipment for replacement to improve the abnormal sound caused by old mechanical equipment. If the equipment cannot be replaced, it is recommended to install sound insulation walls, sound insulation cotton, etc. to strengthen the sound insulation of the process, so as to effectively minimize personnel exposure and ensure Employees are healthy and achieve the goal of sustainable operation.
