Building acoustics. Estimation of acoustic performance of buildings from the performance of elements - Sound absorption in enclosed spaces Ingestion-build-44680 ISO 21809-11 on external coatingsWhat is BS EN 12354 6 Sound absorption in enclosed spaces about? BS EN 12354 6 is the sixth part of the BS EN 12354 multi series that discusses calculation models in building acoustics. BS EN 12354 6 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
