台灣的螺絲製造業相當興盛，產製的螺絲遍佈全球。然而，經過本團隊於螺絲製造業工廠現場勘查，螺絲製造業的現場噪音高達95 dBA，以每日工作八小時計，整個工作日的噪音暴露劑量達200%，遠超過安全標準，極需要進行噪音改善。因此，本研究以一間加工螺帽的廠房為例，利用建置成功的音源與聲場量測、頻譜分析、診斷排序與利用室內聲學軟體針對螺絲製造業工廠噪音進行改善模擬評估，並提出成本－成效分析以供各界參考。應用此項技術進行螺絲工廠噪音改善時，可以讓決策者清楚模擬採用的施作項目功能以及工程經費，使決策者大幅提高選擇改善方案之信心及成效預期心理。

The screw manufacturing industry is quite prosperous, and the screws produced are spread all over the world. However, through factory visits, the on-site noise of the screw manufacturing industry was as high as 95 dBA, and the noise exposure dose reached 200% during the whole working day, which was much higher than the safety standard. The objectives of this study are to establish a noise source survey measurement technique for the screw manufacturing industry through factory visits, to use the spectral analysis technique as basis to establish sound source diagnosis and a noise improvement assessment model, and to complete the case of screw manufacturing improvement design patterns for cost-effectiveness analysis, assessment, and comparison. The application of this simulation analysis technology to improve the noise of the screw factory can enable decision-makers to clearly understand the functions of the improved projects used and the improvement project funding, so that decision-makers can greatly improve the confidence and effectiveness expectations of the choice of improvement project.
