Quick answer: School buildings are measurably louder during term time than the fabric of the rooms was ever designed for. The Easter break is a rare window to think clearly about acoustic performance before the summer term brings it all back. Acoustic wall panels and ceiling baffles are the most practical retrofit for classrooms and halls that build noise rather than contain it.
The Sound Schools Stop Noticing
During term time, school noise becomes background. Chairs scraping. Pupils talking over each other. Instructions repeated, again and again. The hum of a busy hall at lunchtime. It is constant, and because it is constant, it is often accepted as normal.
But “normal” does not always mean “working well”.
The problem with habituation is that it hides cumulative impact. Teachers raise their voices to compete with reflected sound. Pupils mishear instructions and disengage. By the time the bell goes at 3pm, everyone is more tired than the day's activity alone should explain. That fatigue is, in large part, acoustic.
What the Easter Silence Actually Reveals
Walk through your school building during the holiday. Notice what you hear: the creak of a floor, an HVAC hum, your own footsteps bouncing off hard walls. Now mentally press play on a typical lunchtime. How loud does it get? Can you hear someone speaking clearly from the other side of the hall? Does noise feel controlled, or does it build and ricochet?
That thought experiment is genuinely useful. It draws attention to the spaces where hard parallel surfaces, high ceilings, and sparse soft furnishings combine to create long reverberation times. The hall. The dining room. The classroom with render walls and a laminate floor and almost nothing on the ceiling.
The guidance document BB93 (Building Bulletin 93, the SEND-aware acoustic standard for schools in England and Wales) sets reverberation time targets of 0.4 to 0.8 seconds depending on room type and use. Many older school rooms substantially exceed those figures, which is why the problem is felt before it is measured.
How Acoustics Affects Learning and Staff Wellbeing
Classroom acoustics affect three things directly:
- How easily pupils understand spoken instructions, especially those with hearing difficulties, English as an additional language, or auditory processing differences
- How much teachers have to repeat themselves and how loud they need to project
- How fatiguing the day feels, for both staff and pupils
Research consistently shows that speech intelligibility drops in reverberant rooms, and that children are more affected than adults because they rely more heavily on context clues to fill in what they miss. For pupils with SEND, the impact is more significant still.
The implication for school leadership is straightforward: improving acoustic conditions is not an aesthetic upgrade. It reduces the cognitive load on everyone in the room.
Targeting One High-Impact Space
You do not need to fix everything at once. A useful starting point is to identify the single space where noise most consistently causes problems and address that first. Common candidates are:
- Dining halls and canteens, where hard floors, hard walls, and hundreds of simultaneous conversations create the loudest sustained noise in the school day
- Classrooms used for group work or practical activities, where the teaching mode demands more pupil talk and the room provides no absorption
- Corridors and entrance lobbies with tile floors and glazed walls
Targeting one space generates evidence. Staff notice the difference. That makes the case for the next space easier.
For classrooms, wall-mounted acoustic panels fitted to two or three walls typically reduce reverberation by 30 to 50 percent. The Zen Liner acoustic wall panel is Class A rated (the highest absorption classification under EN ISO 11654) and is commonly specified in UK school refurbishments. For spaces where wall area is limited, or where the ceiling is the dominant reflective surface, ceiling baffles and rafts distribute absorption more efficiently.
For halls and dining areas with impact noise from furniture, the Zen Impacta panel combines acoustic absorption with a surface robust enough for the kind of contact schools generate.

Planning Before September: Why Now Is the Right Time
Easter and summer holidays are the two windows in the school year when acoustic work can be carried out without disruption to teaching. Installation of wall panels and ceiling systems typically takes one to three days per room. If the work is planned before the summer term, it can be scheduled and ordered in advance, ready to go the moment the school empties in July.
Waiting until September is not the answer. By then, whatever problems exist will have run for another term and the acoustic environment will be shaping outcomes the whole time.

Frequently Asked Questions
What causes excessive noise in school classrooms?
The main causes are hard parallel surfaces (bare walls, hard floors, glass), high ceilings, and insufficient soft furnishings. These create long reverberation times: sound bounces between surfaces rather than being absorbed, so noise builds up. Rooms with reverberation times well above the BB93 target of 0.4 to 0.8 seconds will feel loud even at moderate activity levels.
What is BB93 and does it apply to my school?
BB93 (Building Bulletin 93) is the UK government's acoustic design standard for school buildings in England and Wales. It sets maximum reverberation time and background noise limits for different room types. It applies to new builds and significant refurbishments, but its targets are widely used as a benchmark for assessing existing spaces. If your school was built or refurbished after 2003, it should have been designed to meet BB93. Many older buildings do not.
Which acoustic products are most practical for school refurbishments?
Wall-mounted acoustic panels are the most common retrofit because they are straightforward to install and immediately effective. Class A rated panels such as the Zen Liner absorb across the full frequency range. For spaces where walls are mostly occupied or where impact resistance matters, the Zen Impacta is a practical choice. Ceiling baffles and rafts work well in large halls where the ceiling is the dominant reflective surface.
How much of a room's surface area needs to be covered with acoustic panels?
A useful starting point is 15 to 25 percent of the total wall and ceiling surface area, though the right figure depends on room volume, existing absorption (carpet, soft seating, ceiling tiles), and how the space is used. A bare-walled classroom with a hard floor will need more coverage than one that already has carpet and a suspended acoustic ceiling. Presentation Spaces can help calculate coverage for specific rooms.
Can acoustic panels be installed during a normal school holiday?
Yes. Wall-mounted panel systems are typically installed in one to three days per room, depending on coverage. No wet trades are involved and no extended drying time is needed. Easter and summer holidays are the most practical windows; half-term can work for smaller jobs. Lead times vary by product, so planning two to four weeks ahead is advisable.
Do acoustic panels help pupils with SEND or hearing difficulties?
Yes, meaningfully. Children with hearing impairments, auditory processing disorder, or English as an additional language rely more heavily on speech clarity and are disproportionately affected by reverberant conditions. Reducing reverberation improves speech intelligibility across the whole class, but the gain is largest for those who are already working harder to follow spoken instruction.
