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 objects. Calculations can only be carried out for frequency bands.
The model is based on experience with predictions for rooms, such as rooms in dwellings and offices, and common spaces in buildings, such as stairwells, corridors and rooms containing machinery and technical equipment.
Note: BS EN 12354-6 is not intended to be used for very large or irregularly-shaped spaces, such as concert halls, theatres and factories.
BS EN 12354-6 on sound absorption in enclosed spaces is useful for:
Sound absorption of enclosed spaces such as rooms in dwellings and office spaces is important as it enhances noise control and prevents speech from getting muffled and muddy.
BS EN 12354-6 describes the principles of the calculation model for sound absorption in enclosed spaces, lists the relevant quantities and defines its applications and restrictions. BS EN 12354-6 helps you to calculate the reverberation time of the enclosed space and helps you identify what materials, temperature, elements and objects contribute to sound absorption within the room.
Overall, the guidelines of BS EN 12354-6 enable you to design rooms with a suitable acoustic environment.EN 12354-6:2003
