Abstract
The aim of this study is to investigate a simplified approach for obtaining ratings of impact insulation of floors which requires only airborne sound measurements and correction factors depending on the particular type of floor finish. One third octave frequency‐dependent correction factors have been obtained by processing published results of both airborne and impact insulation on floors. The uncertainty of predicted Ln,w values using correction factors shows a good agreement with ISO recommended limits. The proposed technique has value in reducing the cost and effort for field insulation measurements. Further work is underway to refine the method and to extend the range of constructions for which we have correction factor.
