Face to face teaching and learning
Good acoustics in classrooms will
- help students and teachers concentrate
- make the teacher’s voice easily reach all students
- make sure that, in group assignments, speech will not spread and disturb others
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 can make both teachers and students feel tired and unfocused.
Challenge
- Reducing sound levels
- Minimising background low-frequency sound
- Ensuring speech clarity
- Preventing the build-up of echoes
- Ensuring speaker and listener comfort
Solution
- 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
