" 國人受到低頻振動及噪音的影響程度日益升高，日常生活品質已受到嚴重的威脅，若能針對低頻噪音及振動的發生機制進行探討以及了解民眾對於低頻噪音振動的感受度，將有助於相關法規的訂定並提高國內民眾的生活品質。本研究透過國外文獻的蒐集來瞭解國際上振動噪音相關法規的趨勢，而國內針對低頻噪音管制標準僅止於空氣音，對於結構振動所引發出的結構噪音並無法可管，若要使低頻噪音相關管理法令更加完善，有必要針對振動源進行管制。國外對於振動之建議值多著重在交通運輸以及建設活動方面，且多數國是依據ISO2631-2訂定振動的相關建議值及評估方法。為與國際趨勢調和，我國振動量測標準之訂定可朝此方向研訂。在本研究中低頻噪音之陳情案件診斷結果發現，主要低頻音來源多數為結構振動所引起之結構噪音，結合人體實驗調查結果發現，在信賴區間95%之統計結果顯示，人體對結構噪音有感時相對應的振動位準為52dB，而陳情案的振動值大多超過52dB，兩者之調查成果大致相符，且調查結果也與103年度之成果相符。本文建議後續研究將以此振動值為參考基準，進一步收集更多陳情案例與人體試驗結果，確認振動管制值的基準及相關管制方法，以使國人生活品質進一步提升。 " "The number of people affected by noise and vibration are increased by the days, and the quality of life are significantly reduced. Therefore a better understanding of the mechanism generating low frequency noise and vibration and the attitude of general public toward the perception of these two sources will be helpful in establishing regulations to enhance quality of life. This research first collected the vibration regulations around the world, whereas, only the low frequency noise regulation are enforced domestically, and there is no law toward vibration regulation and the structure-borne sound associated with it. Therefore, vibration regulation must be established t to make the relating low frequency noise and vibration more more soundly regulated. In other countries, for example Western Europe, vibration regulations are more toward traffic system and most of them use ISO-2631 as their standard for measuring and evaluating vibration exposure. For in harmony with international trend, it is suggesting that the domestic law shall be proposed using this standard. In this research, is it conclude that the cases that the main cause that we have studied with low frequency noise complaint is the structure-borne related sound. And with laboratory experiment, it is found that 52dB with 95% confidence interval is the threshold for the perception of structure-borne sound, which confirms the result from 103 year’s study. Therefore, it is suggested that the follow-on studied use this value as a base to collect more low frequency noise complaint cases and more lab experiment related to the threshold of perception, to established the vibration limits for the related regulations, and therefore further enhance the quality of life for general public.
