噪音作業場所噪音防治與環境監測管理之研究
Research on noise prevention and environmental monitoring management in noise workplace
摘要
本研究主要係針對噪音作業環境監測管理與工程改善減噪進行研究，研究改善成果可提供產業界在噪音作業環境採取相關措施之參考，透過本研究及測試驗證可以確保人員在噪音作業環境透過管理及工程改善，以滾動式PDCA改善方案執行，不斷的進行改善修正，預防噪音作業環境對人員聽力損失之職業危害風險，避免因噪音暴露而導致聽力損失第四級管理（經醫師判定與工作有關者）案例發生。本研究先對噪音作業環境進行噪音源頻譜量測分析，並對主、被動式耳罩進行探討比較，提出可行的噪音防治策略。工程改善評估上第一階段以現況作業環境進行噪音防治檢討，並依現場作業進行改善方案初步驗證。第二階段提出內牆裝設吸音材及對特定噪音源設置活動式隔音屏障2種可行方案，並經音場模擬軟體數值分析預測工程改善成效。管理上提出UHF RFID結合耳罩並建置噪音作業環境監測管理系統，建置後執行相關驗證。高階主動式降噪耳罩有濾通語音頻率功能，故可降低受音者接收的作業噪音音壓外，又具備在高噪音作業中能清楚交談溝通優點。牆裝設吸音材整體空間降噪5.11dB（A），活動式隔音屏障隔音後降噪11.5dB（A）。以UHF RFID耳罩進行噪音作業區人員管制紀錄個人噪音暴露劑量，並藉由相關紀錄進行長期資料統計分析，進行人員噪音暴露音壓追蹤與健康的相關研究，隨作業環境變化以滾動式PDCA不斷檢討改善，達噪音防治最佳化。

This study is the noise monitoring management and engineering improvement noise reduction mainly. The research results can provide reference for the environment of industry's noise reduction. The research and verification can ensure that personnel can avoide cause occupational diseases through the noise environment manage. Engineering improvement and implementation of rolling PDCA improvement program continuous improvement and correction up to prevente the occupational hazard risk of hearing loss in noise working environment. The noise source spectrum measurement analysis is carried out for the noise working environment, and a feasible noise prevention strategy is proposed. In the first stage, the project improvement is assessed. The existing noise prevention and control was reviewed and the preliminary verification of the proposed scheme was carried out in conjunction with the on-site operation. In the second stage, it is proposed that the interior wall is equipped with sound absorbing materials and the movable noise barrier is set. The sound field simulation software numerical analysis is used to predict the engineering improvement effect. In the management, UHF RFID combined with earmuffs to build noise operation environment monitoring and management is proposed. The project performs relevant verification after the implementation and the overall average noise reduction of the sound-absorbing material in the wall is 5.11dB(A). The noise reduction of the movable noise barrier is 11.5 dB(A) dB(A). The UHF RFID and earmuffs are to combine to form one new RFID earmuffs manage system. It can record the personnel in the operation area control the personal noise exposure dose and carry out long-term statistical analysis of the relevant records to conduct personnel noise exposure sound pressure tracking and health related research. With the change of the working environment. To achieve the noise prevention and control optimization by continuously rolling PDCA .
