Building acoustics. Estimation of acoustic performance of buildings from the performance of elements - Sound absorption in enclosed spaces Ingestion-build-96603 alloy desinations1 Scope This European Standard describes a calculation model to estimate the total equivalent sound absorption area or reverberation time of enclosed spaces in buildings. The calculation is primarily based on measured data that characterise the sound absorption of materials and objects. Calculations can only be carried out for frequency bands. This European Standard describes the principles of the calculation model, lists the relevant quantities and
