Acoustics in school buildings - new concepts and recommendations

- Acoustic panel
The study „Acoustics in school buildings - new concepts and recommendations“ deals with the increasing demands on room and building acoustics in the context of modern school buildings, especially in open learning environments and cluster schools.
Key findings of the study
1. Changing room concepts require new acoustic solutions
- New school models such as Cluster and Open learning landscapes are increasingly replacing classic classroom corridor typologies.
- These concepts require differentiated acoustic solutions, as many activities take place simultaneously and in an open environment.
2. High demand for acoustic zoning
- Acoustic design must ensure both speech intelligibility within of groups as well as Shielding between groups.
- It is no longer just about classic sound insulation, but also to Targeted acoustic differentiation within a room.
3. Border area between room and building acoustics
- Partition walls, flexible furnishings and transparent structures (e.g. glass) make it difficult to clearly separate room and building acoustics.
- Both disciplines must be planned more closely together.
4. Reverberation time and absorption surfaces are decisive
- Especially in open learning environments the reverberation time must be Targeted absorber surfaces be reduced.
- The study emphasizes the Importance of materials, which reduces the sound at the place of origin dampen.
5. International role models
- Countries such as the UK and Denmark have already defined specific requirements for open space concepts - Germany is lagging behind.
- These requirements often also include specific information on Sound propagation attenuation, Speech intelligibility (STI) and Masking strategies.
