中文摘要 | 噪音對工廠作業人員的生理及心理上的疾病有高度的影響,因此,對於具有高迴音的密閉系統而言,噪音控制益形顯得重要,然而,為何有維修空間,廠房內的吸音板厚度受到局美,如此一來,如格在有限空 間下將音量控制至最小,便成為一有趣且值得探討的問題,本文將採用單層吸音板並結合遺傳演算法進行分析,在進行最佳化前,為驗數學模式的正確性,將先進行一組樣本的吸音率實測並與理論值做比較,結果顯示,理論值與實測結果頗為吻點,本研究在解決局限空間系統下的吸音板曘佳化設計置,確實提供一種嶄新的解決方法。 |
英文摘要 | Noise is a main contributor to the psychological and physiological illnesses of workers; therefore, it is essential to have noise controlled in an enclosed space with high echo effects. Since the thickness of the sound absorber is usually restrictive, it becomes necessary to minimize the noise under space constraint. In this paper, the optimization of the single-layer absorber, together with genetic algorithm (GA), is presented. Before the optimization, a sample was tested and compared with the experimental data to check the accuracy of the mathematical models. It turned out that both results are in good agreement. This study provides a novel scheme with GA in the optimization of sound absorbers in a constrained sound absorption system. |
