以標準重量軟質衝擊源評估樓板衝擊音之適用性評估

Study on the Applicability of Using Rubber Ball for Standardized Heavy/Soft Floor Impact Sources in Taiwan

摘要


近年,在居住環境品質要求提升下,國人對於建築構造抵抗樓板衝擊音的性能需求逐漸受到重視。而內政部建築研究所的新建住宅性能評估制度中,雖已將樓板輕量衝擊音列入住宅音環境性能的評估指標中,但屬於較低頻的樓板重量衝擊音則尚未納入。我國自1982年至今以國家標準CNS8464所規定之汽車輪胎爲標準重量衝擊源,但目前不但因規範中之汽車輪胎難以取得而造成執行評估之障礙,ISO140-11國際標準亦已於2005年開始採用橡膠球於建築樓板衝擊音的測定。本研究同時採用汽車輪胎與橡膠球,針對國內常用之鋼骨、鋼筋混凝土與木造樓板進行現場實測,探討兩者所產生樓板衝擊音之相關性,以提供未來國內樓板重量衝擊音評估基準之參考,使樓板衝擊音之評估手法能更爲普遍、評估機制更爲完整。

並列摘要


The performance of impact sound insulation of floors becomes more and more importance in recent years. The soft floor impact source has been applied to the system proposed by ABRI for evaluating the acoustical performance of new building. However, the mobile tire used as the standardized heavy floor impact source in CNS8464 since 1982 is hardly available. In this paper, both methods of CNS8464 and ISO140-11 were carried out for studying the correlation between mobile tire and rubber ball, and verified the applicability of using rubber ball for standardized heavy/soft floor impact source.
