（一）Collection and analysis for facilities (include openings of exterior wall in buildings ) and regulations of sound insulation in Buildings. 1.Related regulations and papers with sound insulation of openings of exter- ior wall in buildings, which include Europe, U.S.A, HongKong, and Japan. （1）The regulations of sound insulation in buildings in this study was included IBC and ICC in American, Japan’s Building Standards Law and Dwelling Performance Evaluation Book, HK-BEAM and CEPAS in Hong Kong, Building regulations 2000 approved document E 2003 and BS 8233 （1999） in UK, GB 50352 in China. （2）The sound insulation testing standard in this study was included CNS 15160-5 in Taiwan, ASTM E90 and ASTM E336 in American, JIS A1417 in Japan, BS EN ISO 140-4 and BS EN 20354 in UK, GB/T 19889.3～GB/T 19889.5 in China, International Standard ISO 140-5. （3）Papers with sound insulation of openings of exterior wall in buildings in this study was included “Noise control engineering” by Dan Qun Fang Professor, “Sound transmission through single, double and triple glazing. Experimental evaluation” by António J.B.. 2.Related papers with sound insulation of openings of exterior wall in buildings in Taiwan. （1）The study for sound insulation of buildings in Taiwan in this study was included Building Technical Regulations Article 46, Housing Act Article 37, and Regulations of Grading Housing Performance. In other hand, the paper was studied by Architecture and Building Research Institute (ABRI) which like “The Research of Investigation and Diagnosis Mechanism on Sound Environment of Dwelling Houses” by Fang Ming Lin Professor. （2）The study for sound insulation of openings of exterior wall in buildings in this study was included “Study on the Sound Insulation of the Openings of External Walls in the Residences” by Mr. Song Mao Lin. （二）Analysis for traffic noise and sound insulation of openings of exterior wall in buildings of nearby transportation systems in Taiwan. 1.Acrroding to different transportation systems to select 30 locations for re- search, and describe the test method for traffic noise and sound insulation. （1）The 154 locations for prospecting were finished, and selected 32 locations for research and measurement after discussion with EPA. （2）For test method, traffic noise is by Noise Control Standards for Land Transportation Systems and NIEA P201.94C. Sound insulation test is by CNS 15160-5. 2.To measure traffic noise and sound insulation of openings of exterior wall in buildings for 32 locations. （1）The measurements of SPL of 32 transportation systems locations were finished. The results showed that LAeq of highway and road was about 65 dB（A）～75dB（A）, and LAmax of Rail system in some locations were higher than Noise Control Standards for Land Transportation Systems about 5 dB（A） （2）The sound insulation of openings of exterior wall in buildings of 32 locations were finished. Test results showed the pressurization performance is the main factor for sound insulation of windows, especially need to care about the metal fastener and the chink around window process quality in site. The sound insulation R’45°,w was 17 dB～33 dB for combination windows, but because the sliding window appeared weak between casement and window frame for some cases in this study, it was not good for sound insulation, therefore R’45°,w was 12 dB～31 dB. （3）The sound insulation of exterior wall in buildings of 32 locations were finished. Test results showed the main affection factor for sound insulation of concrete wall was the window’s sound insulation performance. Because some cases of sliding window in this study appeared weak between casement and window frame, therefore it was not good between 630 Hz and 2,000 Hz for sound insulation. The results showed Dls,2m,nT,w was 20 dB～35 dB for concrete wall with sliding window, and 30 dB～37 dB for concrete wall with combination windows. （三）Provide related suggestions for sound insulation of openings of exterior wall in buildings and management of sound insulation in buildings. 1.This study convened a conference for sound insulation of openings of exterior wall in buildings on 10.Dec.2013. 2.Acrroding to test and analysis result to provide related suggestions for sound insulation of openings of exterior wall in buildings in this study, included （1）Improve the pressurization between casement and window frame,（2）Apply for glass thickness, （3）Apply for high pressurization windows, （4）Apply for double glass, （5）Apply R’45°,w ≧ 30 dB for windows, （6）Install absorption materials around the openings of exterior wall in building, and （7）The suggestion values for sound insulation of openings and exterior wall in buildings of overseas. 3.Acrroding to test and analysis result to provide related suggestions for regulations and management of sound insulation in buildings, included （1）The test result applies to Regulations of Grading Housing Performance for R’45°,w ≧ 30 dB, and（2）Provide related sound insulation information which include windows to consumer for reference.
