【 摘 要 】

The sound insulation performance of windows is an important feature of a building’s acoustic environment. Double windows are an extremely effective solution for practical sound insulation on windows. A double window is a window structure comprising two frames and two glass window panes (Fig. 1). The sound insulation performance of windows is usually evaluated by the sound reduction index: SRI. The sound transmission of double partitions has been examined theoretically. Simple and practical methods of predicting SRI have been proposed [1,2]. Although the sound insulation performance of double windows has been examined in some studies [3,4], few experiments to assess actual windows have been reported. For windows, some special differences such as gaps of window frames are expected to affect the SRI. Some method for predicting the SRI of a double window is necessary to design a room’s acoustic environment.
