AIRBORNE SOUND INSULATION OF GLAZING SYSTEMS

The Ookura and Saito model was applied to determine the airborne sound insulation of glazing systems. In particular, the calculations were for monolithic glasses of different thicknesses and laminated glasses of different types. There are different prediction models of the airborne acoustic behaviour of multilayer panels (and the laminated glasses can be considered as such). In all of them, the input data were the elastic constants and the loss factor. The monolithic glasses and the intermediate layer were characterised according to different standards. The results are compared with experimental measurements and data of an earlier study, obtaining a range of acceptable adjustment. 33 refs.
