Measurement and estimation on sound insulation performance of the walls and floors in Taiwan´s dwelling-housings

Countries in the world all build laws and regulations were been request on sound insulation performance of building structure. At present, the building technical regulations haven´t set provisions for sound insulation standards but adopting the way of listing structures. Therefore, to follow the CNS trend of ISO standards for architectural acoustics, this study made a field survey by using ISO 140-4 and 140-7 measurement standards to measure the sound insulation performance of dwelling-housings, and compared that with sound insulation standards of building codes of various countries. The results showed the field sound insulation performance of the wall between rooms of row housing conform to the requirements for sound insulation standards in part countries, while the field sound insulation performance of dwelling-housings structures of floors that included base concrete floors, cement mortar and tiles can´t conform to the requirements for sound insulation standards of any country.
