Quick answer: A normal 8 × 6 m classroom needs about 20 to 28 acoustic panels. At S$185 per panel installed, that is about S$3,700 to S$5,180. A small tuition room needs 8 to 12 panels (S$1,480 to S$2,220). School holidays are the easiest time to install.

Key takeaways

  • Classroom: 20 to 28 panels, about S$3,700 to S$5,180.
  • Tuition room: 8 to 12 panels, about S$1,480 to S$2,220.
  • We work around lessons and holidays.

Why classrooms echo

Classrooms have hard floors, a whiteboard, glass windows and painted walls. Every sound bounces. Students at the back hear the teacher's voice blur, and group work gets loud fast. See how to reduce echo in a classroom.

How many panels a classroom needs

For an 8 × 6 m room with a 3 m ceiling, we usually suggest 20 to 28 panels. Most go on the back wall and the upper side walls, out of reach of little hands. Rooms with very high ceilings may need ceiling panels too.

Cost for different rooms

Panels cost from S$185 each supplied and installed (50 mm, standard fixings included), about S$255 per m². The table below shows the panel count and total for each room type. Scaffold for high ceilings, night or Sunday work and custom sizes are quoted separately.

Classroom and school costs (supplied and installed)

  • Tuition room · Size: 4 × 4 m · Panels: 8–12 · About: S$1,480–2,220
  • Classroom · Size: 8 × 6 m · Panels: 20–28 · About: S$3,700–5,180
  • Music room · Size: 8 × 6 m · Panels: 24–32 · About: S$4,440–5,920
  • Dance studio · Size: 10 × 8 m · Panels: 30–40 · About: S$5,550–7,400

Do panels need to be tough?

Yes. In schools we place panels higher on the wall, use firm edges and choose darker or patterned colours that hide marks. Panels are fixed, not stuck, so they do not come off.

When can you install?

School holidays are the easiest time. We work Monday to Saturday in working hours; night and Sunday installs are possible with a surcharge, quoted case by case. A classroom usually takes less than a day.

Getting the budget approved

A clear quote with the panel count and price per panel is easy to take to your principal, board or PTA. Quotes from photos are free, and quotes are valid for 30 days. Payment is 50% deposit and 50% on completion. See acoustic panels for tuition centres.

Why it matters for learning

When a room echoes, children at the back hear the teacher's voice blur into the next word. They hear sound but miss meaning. Teachers then talk louder all day. Less echo means calmer lessons, and a calmer room can make speech easier to follow.

A simple school plan

Start with the rooms that are loudest: music rooms, the canteen, the hall and the classrooms on busy roads. Do one room first, let teachers try it for a week, then roll out to the rest during the holidays. An 8 × 6 m classroom needs about 20 to 28 panels, which is about S$3,700 to S$5,180 at S$185 each installed.

What we see on real jobs

At Pei School of Dance in Thomson Ridge, we fitted ceiling and wall panels in the studios, corridors and stairs over 2–3 floors. Schools follow the same plan: the biggest hard surfaces first.
