中文摘要	本計畫目標包括建置低頻交通噪音量測規範及評估指標，並瞭解低頻交通噪音類型。提出改善建議對策，輔導營建業者改善低頻噪音。藉由舉辦諮詢會議及說明會，達到經驗交流及培養低頻噪音專業知能。共完成快速道路、高速公路、一般道路、高速鐵路、一般鐵路及大眾捷運系統等陸上交通運輸系統之監測作業共計 28 點次。針對在 20-200Hz 範圍之音量，小時均能音量多在 50 至 60dB(A)間。在快速道路、高速公路之下方與路外之測點，多半為下方值高於路外值。即使有隔音牆存在時，仍屬下方值高於路外值。可能因高架型式、路面接縫等因素所導致。由道路系統包括快速道路、高速公路及一般道路測點的 20-200Hz 頻譜分析結果，並無顯著的主要頻率。但有部分測點由於現場通過之貨車較多，在 63Hz 及 80Hz 有較高現象。在軌道系統方面，捷運測點因上下行軌中間有開口部，因此其下方之測值均較路外測值高。一般鐵路在全頻亦是下方測值較路外測值高，但低頻則有一點是路外大於下方，高鐵低頻量測結果則發現路外高於下方，但有隔音牆之測點該隔音牆有發揮作用。針對路外測值之 20-200Hz 小時平均最大音量，捷運測值分布在 51.6dB(A)至 69.8dB(A)。鐵路因為有不同車種，所以測值分布較廣，約在 58.2dB(A)至70dB(A)，高速鐵路測點分布在 59.2dB(A)至 69.3dB(A)。高速鐵路測點則在隧道口附近有較明顯的低頻噪音及超低頻噪音；與日本的門窗振動臨界值進行比較，在我國低頻範圍 20-200Hz，以高速鐵路測點在 31.5Hz 以下會有超過該臨界值的情形。至於高速公路、快速道路、一般道路或鐵路，在20-200Hz 範圍均低於該臨界值。會發生超過臨界值現象者均在10Hz 以下。綜合量測結果，針對低頻噪音量測評估指標，本計畫建議在軌道系統以通過車次的小時平均最大音量，道路系統以小時均能音量來評估，但道路有大型車輛多時亦可紀錄最大音量求得小時平均最大音量值以茲評估其影響。共完成 10 處營建工程現場輔導及量測工作，向工地人員宣導及解釋低頻噪音管制標準內容及解答其對法規的疑惑。並對工地內產生明顯噪音的機具設備或施工行為，因地制宜提出建議。共完成26 點次在戶外距建物牆面約 1 至 2 公尺處或機具前之監測，以評估營建噪音對民宅可能的影響，音源多為挖土機、預拌車引擎、發電機所發生的聲音。在現場建議業者避免朝向噪音敏感地點以及必須透過汰舊換新或定期保養維護等方式來儘量減少噪音量。於12 月 10 日完成乙場營建低頻噪音防制及改善說明會，共有 50 多位來自政府工務機關及營造相關業者及與會，向其說明輔導成果及即將於 98 年 1 月 1 日施行的低頻噪音管制標準內容，提昇與會人員對於法規的認識及瞭解。

摘要	The study comprised three objectives, the first objective is to propose the measurement guideline and index of low frequency traffic noise, and try to find the pattern of the low frequency traffic noise. The second objective is to provide help with field survey of some construction sites and measure low frequency noise in such sites then offered the guidance report in accordance with the noise state. The third objective is holding a meeting which invited the persons from construction society and competent authorities. The measurement of low frequency traffic noise were implemented in 28 spots such as expressways, highways, ordinary roads, high speed trains(THSRC), ordinary trains and mass rapid transit trains(MRT). For the 20-200Hz frequency noise, the hourly-equivalent energynoise were among 50-60dB(A). The noise under the expressway and highways were higher than the noise beside the mentioned ways, in spite of the barriers. The cause might be the different type of flyover and joints of the ways. According to the frequency analysis results, there were no distinguished main frequency patterns among the roads. Only the roads where there were more trucks, the 63Hz and 80 Hz frequency were a little peak. Among the track system, because there is open area in the flyover of the MRT system, the noise will transmit through it, the noise under the MRT track is high than the noise beside the track, as well as the ordinary trains. The noise from the THSRC under the track was lower than the noise beside the tracks. And we found that the barriers were effective. For the hourly-equivalent energynoise beside the track, the MRT were 51.6-69.8dB(A), the ordinary trains were 58.2-70dB(A), the THSRC were 59.2-69.3dB(A). The noise from the tunnel of THSRC was higher in low frequency and infrasound. Compared with the threshold of rattling fittings of Japan, some spots of THSRC was over in 31.5Hz. The others over threshold situation were in infrasound. For the index of track system, we suggested the average Lmax noise of one hour passing trains. For the index of roads system, the hourly-equivalent energyenergy noise was suggested or if there will be many trucks, the average passing Lmax noise is also recommended. In field survey of ten construction sites, the experts were invited to provide noise improving suggestion in situ and explain the low frequency limit in Noise Control Standards of construction sites. Twenty-six spots were measured in front of several buildings or machines to evaluate the noise to the buildings. The sources were such as excavators, cement mix trucks and generators. The suggestions were such as prevent the noise from pointing to sensitive areas and maintain the machines frequently.

摘要

The study comprised three objectives, the first objective is to propose the measurement guideline and index of low frequency traffic noise, and try to find the pattern of the low frequency traffic noise. The second objective is to provide help with field survey of some construction sites and measure low frequency noise in such sites then offered the guidance report in accordance with the noise state. The third objective is holding a meeting which invited the persons from construction society and competent authorities. The measurement of low frequency traffic noise were implemented in 28 spots such as expressways, highways, ordinary roads, high speed trains(THSRC), ordinary trains and mass rapid transit trains(MRT). For the 20-200Hz frequency noise, the hourly-equivalent energynoise were among 50-60dB(A). The noise under the expressway and highways were higher than the noise beside the mentioned ways, in spite of the barriers. The cause might be the different type of flyover and joints of the ways. According to the frequency analysis results, there were no distinguished main frequency patterns among the roads.
