Some aspects to improve sound insulation prediction models for lightweight elements

The best approach to include lightweight building elements in prediction models for airborne and impact sound insulation between rooms, as in EN 12354, is not yet completely clear. Two aspects are at least of importance, i.e. to derive the sound reduction index R for lightweight elements for resonant vibrations only and the appropriate method to...

A blast absorber test: Measurement and model results

A blast absorber test was conducted at the Aberdeen Test Centre from 13 to 17 June 2005. The test was set up to determine the absorbing and shielding effect of a gravel pile, of 1.5 meters high and 15 by 15 meters wide, on blasts from large weapons: e.g. armor, artillery or demolition. The blast was simulated with single brick C-4 charges of 570...

Possibilities to improve the modelling in EN 12354 for lightweight elements

The standard EN 12354 gives prediction models for the airborne and impact sound transmission between rooms in buildings. For buildings with mainly heavy, monolithic structures the standard has proven to be quite useful. However, in case of lightweight building elements the standard only gives global indications about the appropriate modelling....
