勞工意識抬頭的現今，除了有安全衛生的作業場所外，健康舒適的環境也越來越重要。「噪音」是作業環境中存在的物理性危害因子之一，噪音除了會造成聽力損失外，還會造成其他生理及心理上的健康效應，進而降低工作效率及意外傷害機率增加。 一般進行個人噪音暴露評估時通常使用噪音劑量計作為評估測量的工具。此儀器可得知受試者當天的總暴露劑量，但對於暴露的詳細位置與其停留的時間卻無法得知。在作業環境測定中，瞭解暴露的成因、暴露的時間、暴露地點、暴露變化的趨勢等資訊，可以有使工程人員採取更經濟有效的手段來控制噪音，對於健康處近人員而言也能夠發展更為實際的噪音保護計畫。 為了能夠精確的量測勞工噪音暴露位置即暴露量，並且進一步提供即時噪音暴露資訊，本研究整合噪音感測技術、無線通訊技術、電子控制技術、網路傳輸技術與資料收集管理技術，開發出一套完整地即時噪音暴露評估與監測系統。此系統可將即時噪音分貝值以無線通訊的方式傳遞至監控伺服器，並且在通訊過程中得知勞工所在位置，最後管理者可於系統中即時監測勞工之時間-活動情形與暴露量等資訊，同時當勞工之暴露量超過法規值時，系統會即時的發出警示訊號，告知勞工進行必要的防護措施。 在實驗室利用自走車模擬勞工於噪音作業環境中的結果顯示，系統記錄值與噪音劑量計值兩者具有高度相關(R=0.94)，且其檢定結果也顯示兩者所得到劑量值間無統計上差異，即代表本研究以成功的整合出一套可應用於勞工即時暴露監測的系統。但是本研究只在實驗室進行模擬，需進一步於實場進行測試，以評估系統於作業環境現場運作的可行性。 These days, labor consciousness is raising. To be capable of having safe and hygienic workplace, it is very important to work at a comfortable and healthy environment. ”Noise” is one of the dangerous physical factors at a workplace. Noise damages the hearing and affects the physical and psychological health which decreases work efficiency and increases the probability of accidental injury. Basically, we use dosimeter to estimate the worker noise exposure. This instrument can measure the total personal noise exposure dose, but it can not identify the exact exposure location and the amount of staying. Understanding the reason, time, location, and the change of exposure can help engineers control noise economically and efficiently. These information can also assist hygienic promoters to set up more practical plans for protection from noise. In order to measure worker’s location of exposure and dose of exposure precisely and provide the exposure information of noise immediately, this research combines noise sensing technology, wireless technology, electronic control technology, network technology and data management technology to build a noise exposure assessment and monitor system. This system can wirelessly send decibel that are instantly monitored making the worker’s location identified at once. The manager can monitor laborer’s working-hour, activity and dose of exposure by using this system. At the same time, when the dose of exposure exceeds the legal standard, the system will notify the laborers to invoke necessary protection. The Laboratory tests showed that noise exposure dose measured by self-developed system were highly correlated with that obtained by the noise dosimeter (R=0.94) and there is no statistical difference. The results demonstrated that the system is capable of being a great method for worker’s noise exposure assessment and monitor.
