Aim
To help maintain comfortable sound levels by limiting reverberation times.
Detailed requirement
Part 1: Reverberation Time
The following spaces have maximum reverberation time (RT60) as described:
- Conference rooms: 0.6 seconds.
- Open workspaces: 0.5 seconds.
Part 2: Reverberation Time for Learning Spaces
Reverberation time measurements for learning spaces meet the following criteria:
- Spaces less than or equal to 3,000 m³ [10,000 ft³]: less than 0.6 seconds.
- Spaces greater than 3,000 m³ [10,000 ft³] and equal to or less than 6,000 m³ [20,000 ft³]: less than 0.7 seconds.

Our contribution
In the context of green architecture, products from the Acoustiver sub-range (Novelio® Renovation) are designed to improve thermal and acoustic comfort while helping in heavy renovation jobs.
More specifically, this range helps to reduce echo phenomena and absorbs up to 40% of noise pollution according to the ISO 11654 norm.
Based on the ISO 354 norm, the acoustic absorption coefficient αw is 0.25.
