Why School Acoustics Matter
Learning depends on hearing the teacher clearly. Excessive reverberation and background noise reduce speech intelligibility, especially for younger children and those with hearing difficulties. Good acoustic treatment supports learning and reduces teacher vocal strain.
Key Goals
- Control reverberation time (RT60) so speech is clear.
- Keep background noise low (from HVAC, corridors and outside).
- Limit noise transmission between classrooms (sound insulation).
Treatment Approach
- Add absorptive treatment to the ceiling and upper walls to shorten reverberation.
- Treat the rear wall to reduce late reflections reaching the teacher.
- Ensure adequate insulation of separating walls (see absorption vs insulation).
Relevant Standards
- ISO 3382-2 — reverberation time in ordinary rooms.
- ANSI/ASA S12.60 — classroom acoustics criteria (where adopted as a reference).
Limitations
Target reverberation values are application-specific and should follow the relevant guideline for the room type and age group, not a single universal number. Both absorption and insulation are usually needed.

Frequently Asked Questions
What reverberation time should a classroom have? Follow the applicable guideline for the room and age group; confirm by measurement.
Do classrooms need sound insulation too? Yes — reduce noise between classrooms with insulated walls, in addition to in-room absorption.
