標題: | 綠帶型式與配置方式對減低噪音之研究(2/2) | 作者: | 張育森 | 關鍵字: | 植物;減音;相對衰減;Plant;Noise reduction;Relative attenuation | 公開日期: | 2005 | 出版社: | 臺北市:國立臺灣大學園藝學系暨研究所 | 摘要: | 本研究探討35 種樹帶的減音效益。在樹帶前方施放音源,於樹帶內部不同地點設 置噪音計測量噪音。重要的參數包含樹帶的可見度、寬度、高度及長度。採用逐步迴歸 法來探討樹帶減音因子的重要性,結果顯示可見度與相對衰減呈現對數負相關,寬度、 高度及長度與額外衰減呈現對數正相關。最後將可見度與寬度的額外衰減值投影在圖 面,趨勢擬和線的結果可以作為樹帶減音的實質建議。 This study investigates the noise reduction effect of 35 evergreen-tree belts. A point source of noise was positioned in front of the tree belts and the noise level at various points in the belts were measured with a noise meter. Factors important for noise reduction include visibility, width, height, and length of the tree belts. Stepwise regression was employed to examine the factors associated with noise reduction. A negative logarithmic relationship between the visibility and relative attenuation was found. A positive logarithmic relationship between relative attenuation and the width, length or height of the tee belts was also found. A map showing the relationship between visibility together with width was plotted. The map provides some practical suggestions concerning design of tree belts for noise reduction. |
