Title: Experimental investigations on sound insulation through single,double & triple window glazing for traffic noise abatement
Authors: Garg, Naveen; Sharma, Omkar; Maji, Sagar
Abstract: This study presents sound insulative sandwich window constructions of high sound transmission class (STC) value forabatement of traffic and aircraft noise in Delhi city. An empirical relationship correlating with thickness of glass for variouswindow configurations has been developed. Significant increase in sound insulation is observed at higher frequencies when eitherone glazing is double or both glazing are double. Increasing thickness of glass pane, coincidence dip shifts towards lower frequencyand also with increasing air gap, a significant improvement in sound insulation characteristics in both low and high frequencies isobserved.
