Quick answer: School halls echo because they are large, hard and used for assemblies with large groups. Acoustic panels on the rear and side walls and in the ceiling make speech clearer for assemblies, performances and exams. Hall projects are often scheduled during school holidays and can be phased to match budgets.
Key takeaways
- Rear and side walls first; ceiling in tall halls.
- Install during school holidays.
- Phase to match budgets.
Why halls echo
A school hall is a big room with hard floors and walls. There are few soft surfaces to soak up sound. Speech from the stage keeps bouncing, so students at the back hear a blur.
What to treat
Start with the rear wall, which sends sound back to the stage. Then treat the side walls. In tall halls, add ceiling panels last.

Scheduling
School holidays are the easiest time to install. Big halls can take several days, so plan a term ahead. We work Monday to Saturday in working hours; night and Sunday installs are possible with a surcharge.
Cost
Panels cost S$185 each installed. A 20 × 12 m hall usually needs 152–206 panels, which is S$28,120–S$38,110. Phasing by wall spreads the cost over more than one budget year. See classroom echo.
Sports hall considerations
If the hall is also used for ball games, keep panels high, well above where balls fly. Panels below about 2.5 m in a sports hall should be protected or avoided. The high ceiling is usually the best place for panels, because it is out of reach and holds most of the echo.
Assembly clarity
Clearer assemblies reduce the need to raise the PA volume and help children at the back follow announcements. Most echo in a hall comes from the high ceiling and the bare rear wall. Treat those first, and a calmer room can make speech easier to follow.
What we see on real jobs
Hall projects are best planned a term ahead so they fit school holidays.
