摘要

由於噪音對人造成生理及心理上的傷害，因此，對工廠故音量控制是非常重要的，為了降低對環境的衝擊，在工業界最常長久被使用的防音措施為隔音牆，然而，此隔音牆的設計是費時的，為經濟地改善噪音，近年來，另一種彈性且快速調變音源位置，以降低周界音量的新音量防制措施已被提出，然而，其在音量改善的成效上仍然不足，為了經濟、快速且有效地降低周界噪音，以隔音牆外型最佳化結合調變音源位置以降低周界音量的方法遂被提出。 本文中，將應用模擬退火法結合理論音量傳播及最小平方根法，來進行隔音牆外型及音源位置最佳化設計，在進行音源辨識之前，將進行單音源擴散模擬並與實測值相比，以驗證本數學模式的正確度，此外，三種隔音牆系統亦進行數值最佳化，結果顯示隔音牆外型及音源位置能被最適化。最後，本研究確實能針對多音源工廠的隔音牆外型及音源位置最佳化，提供一套既快速又有效的方法。

Because high noise levels in industrial plants can be injurious to workers and lead not only to psychological but also to physiological ailments, noise control in factories becomes essential. In order to overcome the noise impact emitted from a multi-noise plant, a sound barrier, a popular noise control strategy, has been used in the industrial field for a long time. Yet, the traditional method in the design of a sound barrier is time-consuming. Recently, to economically improve acoustical performance, a new strategy (flexible allocation) is applied; however, the acoustical performance is still insufficient. In order to quickly, efficiently, and economically control the noise level specified by the Environmental Protection Administration, interest in shape optimization of a sound barrier in conjunction with equipment allocation around the plant's boundary is rising.
In this paper, the novel technique of simulated annealing (SA) in conjunction with the theoretical sound propagation model and the method of minimized variation square is applied in the following numerical optimizations. Before a sound barrier is optimized, the sound propagation from one single noise is tested and compared with the experimental data for the purpose of accuracy within the mathematical model. Moreover, two kinds of sound barrier systems have been fully discussed and optimally shaped by the SA. The results reveal that the sound barrier can be properly shaped. Consequently, this paper may provide an efficient and rapid methodology in the shape-optimized work for a sound barrier installed in a multi-equipment plant.
