Learning by focused collaboration
In an open-plan space, sound needs to be contained as close to the source as possible. This will reduce the risk of escalating speech levels and enable group and teacher communication with high speech clarity and listening comfort.
The most common activities in these spaces are different kinds of group work. If acoustics is not dealt with properly, sound will spread throughout the space and disturb all the other classes and groups. This will lead to a build-up of intrusive sounds, and particularly low-frequency sound, making students have to raise their voices, in turn escalating sound levels. All in all it would lead to a space where students have trouble focusing, and where teachers have trouble helping and instructing the students.
- Reducing sound levels
- Stoppiong sound from spreading throughout the space
- Increasing speech clarity
- Use a sound-absorbing ceiling with good absorbing qualities in all speech frequencies
- Use wall absorbers next to as many group seatings as possible
This recommendation is for this particular activity and space, based on a comparison between Ecophon products. The scale applied ranges from 1 to 5, where 5 is the highest score. For indoor air quality, 5 equates to compliance with French VOC A+ and California Emission Regulation standard, and 4 equates to French VOC A and M1 (The Finnish Emission Classification of Building Material).
