Samenvatting
This document 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 characterises the sound absorption of materials and objects. Calculations can only be carried out for frequency bands. This document describes the principles of the calculation model, lists the relevant quantities and defines its applications and restrictions. It is intended for acoustical experts and provides the framework for the development of application documents and tools for other users in the field of building construction, taking into account local circumstances. The model is based on experience with predictions for rooms, such as living rooms and offices, and common spaces in buildings, such as staircases, corridors and rooms containing machinery and technical equipment. It is not intended to be used for very large or irregularly-shaped spaces, such as concert halls, theatres and factories.
