Acoustics 2015 Hunter Valley 15-18 November 2015Abstract: This paper presents the results of a case study of the achievable sound reduction of glazing treatments for a typical South Australian residential property. A loudspeaker, located externally, was used to generate a broadband noise signal and the resultant internal noise levels were measured for each glazing treatment. The treatments included retrofitting a double hung timber window, built in the late 1800’s, with Magnetite glazing systems of different thicknesses and air cavity sizes, as well as upgrading the existing window suite with thicker laminated glass and acoustically rated seals. The study compares each glazing system and discusses the effect that each window upgrade has on predicted internal noise levels from a road traffic noise source.
