摘要
The slits on the lightweight partitions have a significant effect on sound insulation which is investigated in this paper. According to Gomperts model for rectangular aperture, the sound reduction index of a wall with slits can be predicted. Two lightweight partitions were selected to analyze their sound reduction index variation with factors such as width, length and location of slits. Results show that these factors affect the sound insulation evidently, especially at high frequencies.
