Standardized prediction methods for estimating sound insulation in buildings

Trevor Nightingale, Thomas Alber

Abstract


In Europe, `objective' or `performance' based building codes spurred the development of standardized methods to predict the sound insulation of buildings. These models are reviewed and their suitability for North American constructions are examined. The ability of CEN model (prEN 12354-1), DIN 4109 and ONORM 8115 to predict the sound reduction of the transmission and flanking paths is discussed.
