Abstract
Experimental sound transmission loss data for double-glazed windows have been compared with the predictions of several theoretical models. Simple equations that provide a satisfactory empirical fit to the data were found. The transmission loss of double glazing was compared with that of triple glazing; the results are very similar when the combined interpane spacings of the triple window match the spacing of the double glazing. The triple glazing did, however, exhibit consistently higher transmission loss both at frequencies below the mass-air-mass resonance and in the vicinity of the coincidence dip.
