适用范围：The document specifies a calculation model to estimate the sound insulation or the sound pressure level difference of a facade or other external surface of a building. The calculation is based on the sound reduction index of the different elements from which the facade is constructed and it includes direct and flanking transmission. The calculation gives results which correspond approximately to the results from field measurements according to EN ISO 140-5. Calculations can be carried out for frequency bands of for single number ratings.
