The level of acoustic performance required is dependent on the room type but the common requirement is effective reverberation control, e.g. school corridors require Class C absorber or above. Class A offers the highest level of absorption and
greatest reduction of reverberation times.
*The definition of a traditional building is a building or part of a building of a type constructed before or around 1919:
a) using construction techniques that were commonly in use before 1919; and
b) with permeable component, in such a way that promotes the dissipation of moisture from the building fabric.
