摘要
Abstract
When studying the influence of screw connection on the sound transmission characteristics of the panel-stud partitions, the spacing of screws is considered as an important factor for predicting the sound insulation effects of the partitions. The screws can be modeled as a series of independent points or as a line connection along the stud, depending on the screw spacing and concerned frequency. For the small screw spacing, the connection between the panel and stud can be treated as a line connection and has high sound transmission effect and low sound insulation effect. While for the large screw spacing, the connection can be treated as independent point connection and has high sound insulation effect and low sound transmission effect. The distinction of the two connections is related to the frequency. Usually, the line of distinction is that the half bending wavelength is equal to the screw spacing. Experimental results also demonstrate the influence of the screw spacing on the sound insulation of the partitions. Finally, the prediction methods of the sound insulation of the partitions are discussed.关键词
