Abstract
This study presents sound insulative sandwich window constructions of high sound transmission class (STC) value for abatement of traffic and aircraft noise in Delhi city. An empirical relationship correlating with thickness of glass for various window configurations has been developed. Significant increase in sound insulation is observed at higher frequencies when either one glazing is double or both glazing are double. Increasing thickness of glass pane, coincidence dip shifts towards lower frequency
and also with increasing air gap, a significant improvement in sound insulation characteristics in both low and high frequencies is observed.
