本計畫針對營建工程噪音進行實地量測，期能建立營建工程低頻噪音管制標準。營建工程噪音有下述特性：（一）與工廠噪音比較時，其影響期間相對較短；（二）撞擊式噪音較多，且音量大；（三）開放性施工，減音措施較不易實施；（四）不同施工階段施工機具及工法不同，噪音特性不同。因此在訂定標準值時必須考慮前述特性。為使稽查作業具備一致性，建議營建工程低頻噪音管制的規範應與現行娛樂、營業場所及即將實施的工廠（場）相同，採用20至200Hz頻率範圍進行管制。綜合94年及95年計畫兩年來共40處營建工程噪音監測結果，關窗2分鐘低頻噪音（20-200Hz）均能音量，若訂為49分貝，則約有28%會超出標準。本計畫已依量測結果初擬出標準值草案，但由於兩年來量測點數僅40點，建議未來可再進行更多量測以使標準值制定基礎更形完備。除標準草案外，本計畫完成了5件噪音源鑑定及改善因應對策建議，包含了來自工廠、停車塔、鼓風機馬達等音源，均是民眾長期受到低頻噪音干擾的個案，其中有些經過改善建議後可以獲得改善，但泰半案例的量測結果係符合現行或未來即將施行的管制標準，推斷是陳情人本身對於噪音比較敏感。因此此類特殊案例，必須加強陳情人跟被陳情單位進行溝通。另為使一般民眾或相關業者對低頻噪音有基本瞭解，本計畫編輯了低頻噪音防制手冊草案，提供有興趣了解低頻噪音的民眾或廠商這方面的知識。在會議方面，完成1場說明會、1場諮詢會及1場專題演講。

This study measured the noise from several construction sites and tried to establish the criteria of the low frequency noise for construction sites. The noise from construction sites has the following characteristics: (1) While comparing with the noise of the factory, it is relatively short while influencing; (2) There are more striking type noises, and the volume is great; (3) It is more difficult to implement noise abatement because usually the sites are open; (4) The machines are different while different stages of constructing, the noise characteristics are different. It needs to consider the above-mentioned characteristic while stipulating criteria. For consistency, the measurement methods need to be the same with current factories and business places low frequency noise standards. As for the limit, in 2005 and 2006, forty construction sites noise were measured. While the windows were closed, the low frequency (20-200Hz) equivalent noise for two minutes, if it is 49 decibels, nearly 28% will go beyond the standard. Although the draft criteria was proposed in this study, we suggested that more measurement need to be implement because forty samples were too few to support the results. Besides standard draft, this study has been finished fives cases for noise complaint. The noise comes from factory , parking tower, air-blower motor enharmonic etc. Among them some can be being improved after suggestion proposing, but some measurement results were not over the criteria. It was possible that the complainant was more sensitive to the noise. This kind of cases must strengthen with relation and communication between the two parties. A draft booklet for low frequency noise control was edited, it will offer to the people and manufacturer who are interested in such topic. This study also implemented three meeting for consultation meeting and a specialist lecture.
