Face to face teaching and learning
The most important thing in a classroom is speech clarity - for both teachers and students, both in traditional teaching and in group assignment.
If a classroom has poor acoustics:
This will make both teachers and students feel tired and unfocused.
| Product combination | Low frequency (125 HZ) | Total acoustic performance | Impact resistance / Durability | Indoor air quality | Ceiling surface |
| 5 | 5 | 5 | 5 | Reinforced Akutex™ FT | |
| 5 | 5 | 3 | 5 | Akutex™ T | |
| Ceiling: Gedina Wall: Akusto Wall |
3 | 3 | 3 | 5 | Akutex™ T |
The recommendation above 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).The gamma surface is to be used for the speech-reflecting zone.
