Abstract
A glazing panel and hollow glazing panel, the hollow glazing panel including a first pane, a second pane held in spaced-apart, face-to-face relationship with the first pane, and a plurality of localized damping members positioned between the first and second panes, adherent thereto, and distributed therebetween over the area of the opposing faces thereof, wherein the first pane comprises a pair of vitreous sheets and an intervening layer of polymeric material separating the sheets of the pair and to which the sheets adhere, wherein the first pane has a shape, an area, and a total mass of vitreous material, and may be compared to a notional monolithic vitreous sheets having a coincidence frequency (.phi..sub.m) and a critical frequency of coincidence, wherein the first pane has a coincidence frequency (.phi..sub.p) and at least one critical frequency of coincidence, and wherein the intervening layer has viscoelastic properties such that the lowest critical frequency of coincidence of the first pane is greater than the critical frequency of coincidence of a notional monolithic vitreous sheet having the same shape and area as the first pane and having a mass equal to the total mass of…
