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:
- low-frequency sounds will distort speech
- sound will bounce off ceiling and walls and create echoes
- sound levels will escalate
- students and teachers will have to raise their voices to be heard
This will make both teachers and students feel tired and unfocused.
- Reducing sound levels.
- Minimising background low-frequency sound.
- Ensuring speech clarity.
- Preventing the build-up of echoes.
- Ensuring speaker and listener comfort.
- Use a sound-absorbing ceiling with exceptional absorption qualities for all speech frequencies, and particularly low frequencies.
- Add wall absorbers on the back wall for traditional teaching, and on two adjacent walls for group teaching.
- Add a speech-reflecting zone in the ceiling above the teacher for traditional teaching.
