摘要

世界各國透過營建體系法規要求建築物構造基本隔音性能，以降低不同使用單元間噪音干擾，反觀我國現行建築技術規則相關條文則僅規定牆板構造材料及厚度，並未規定構造隔音基準，相關議題值得探討。本研究針對國內住宅分戶牆及樓板，應用新制訂CNS 15160-4與15160-7 隔音量測法進行現場隔音，性能量測及評定，並與國外建築法規分戶牆及樓板隔音基準比較分析。結果發現，國內住宅常見150 mm 厚RC牆表面水泥砂漿粉刷分戶牆，現場隔音等級可達50 dB以上，具良好隔音性能與國外隔音基準要求相當，此隔音量測數值與牆板隔音理論計算經比對分析結果趨勢一致，具高相關性顯示本研究分戶牆測試結果真有效性。此外，國內住宅常見RC 裸樓板、水泥砂漿及地磚組成之樓板，經現場量測整體隔音性能不佳，隔音等級無法符合國外隔音基準要求，故樓板無採取有效防制對策，其衝擊音將成為集合住宅住戶困擾噪音源。故為提升我國住宅音環境品質，建築法規應增修訂隔音相關基準，確保建築隔音性能。

The building codes regarding the basic sound insulation performance of building structure to reduce the environmental noise between units have been legalized worldwide. However, the provisions for sound insulation standards have not been regulated in domestic building technical regulations but adopting the way of listing structures. Therefore, to follow the CNS trend of ISO standards for architectural acoustics, this study made a field measurement by using CNS 15160-4 and 15160-7 to measure sound insulation performance of existing dwelling houses, and compared the measurement with sound insulation standards of other various countries. The results showed the 150 mm RC and cement mortar common wall between dwellings was conformed the regulation of some countries and filed insulation performance level was 50. While the field sound insulation performance of dwelling-houses with base concrete floors with cement mortar and tiles could not be conformed to the requirements for sound insulation standards of any country. Thus, to improve the residential sound environment and living quality, this study suggests that it should take sound insulation standards of other countries as reference for building technical regulations in our country and revise the relative clauses.
