| Title |
An Experimental study for the improvment of sound insulation performance in the exterior window |
| Abstract |
This paper is aimed to investigate the improvment of sound insulation performance by variation of the design factors such as size of window, thick of glass, air-tightness, window materials and construction methods etc.As a results, the sound insulation perfomance of window was greatly improved by reducing the samll leaks around the window frame but slightly improved by increasing the thick of galss and installating the absorption meterials between the window frames. |
