Quick answer: Acoustic panels reduce classroom noise by absorbing the echo that builds up off hard walls, ceilings and floors, making speech clearer and lessons easier to follow. For most classrooms the effective approach combines fabric-wrapped wall panels with ceiling rafts or baffles, sized to meet the reverberation targets in Building Bulletin 93 (BB93). This guide explains what to fit, how much, and why it matters for learning.
Noisy classrooms are not just uncomfortable, they measurably harm learning, especially for younger pupils, pupils with hearing or attention needs, and anyone learning in a second language. Acoustic panels are the most direct fix. Here is how to specify them properly for a school setting.

Why classroom acoustics matter for learning
In a hard-surfaced room, sound reflects repeatedly before it fades, so a teacher's voice arrives mixed with its own echo and the noise of the class. This raises the effort pupils need to understand speech and lowers concentration. Children are more affected than adults because they are still developing the ability to fill in misheard words from context. Reducing reverberation is the single most effective acoustic improvement a classroom can make. For practical day-to-day tactics alongside panels, see our guide on 15 steps to reduce classroom noise.
What BB93 requires
Building Bulletin 93 (BB93) is the UK standard for acoustics in schools. It sets maximum reverberation times for different room types, with general teaching spaces typically targeted around 0.6 seconds or lower depending on the space. New-build and major refurbishment projects must meet BB93, and existing schools improving their environments use it as the benchmark. Meeting it almost always means adding absorptive panels, because bare plaster, glazing and hard flooring reflect far too much sound on their own.
The right panels for a classroom
Fabric-wrapped wall panels
Wall panels are the workhorse of classroom acoustics. They absorb the speech-frequency sound that causes the most disruption and can be colour-matched to the room. The Zen Acoustic Pin Boards are particularly useful in classrooms because they absorb sound and double as a pinnable display surface, so a single panel earns its wall space twice over.
Ceiling rafts and baffles
Where walls are taken up by windows, whiteboards and displays, the ceiling is the largest available absorptive surface. Horizontal Zen Raft clouds and vertical Zen Baffle fins treat a large floor area from above, which is often the most effective way to bring down a classroom's overall reverberation. The lightweight Zen Light Raft and Zen Light Baffle suit ceilings where loading is a concern. For more on how these work, read acoustic ceiling rafts and baffles explained.
Combining the two
A typical compliant classroom pairs wall panels (to control reflections at ear level) with ceiling treatment (to bring down overall reverberation). The exact mix depends on room size, ceiling height and how hard the surfaces are. This is why a measured acoustic assessment, rather than a fixed panel count, gives the most reliable result.
How many acoustic panels does a classroom need?
As a working guide, treating around 15 to 20 percent of a classroom's total surface area produces a clear improvement, with more needed in rooms with very hard surfaces or a strict BB93 target. A standard classroom commonly needs a combination of several wall panels plus ceiling rafts or baffles. Because room volume and surfaces vary so much, the most accurate way to specify is a measured assessment of reverberation time.
Special considerations: SEND and inclusive classrooms
Good acoustics matter even more in inclusive settings. Pupils with hearing impairment, autism or attention and language needs are disproportionately affected by classroom noise, so acoustic treatment is an inclusion measure as much as a comfort one. Funding routes such as SEND capital can often be used for acoustic improvements. See how acoustic design supports autistic learners and how schools are funding acoustic improvements for SEND pupils.
Frequently asked questions about classroom acoustic panels
Do acoustic panels really reduce classroom noise?
Yes. Acoustic panels absorb sound that would otherwise echo off hard surfaces, which reduces reverberation and background noise build-up. The result is clearer speech and a calmer room. Panels do not block noise coming through a wall from next door, which is a soundproofing issue, but for the echo and noise build-up inside a classroom they are the right and effective solution.
How many acoustic panels does a classroom need?
As a rough guide, treating 15 to 20 percent of the room's total surface area gives a noticeable improvement, with more required for very hard rooms or a strict BB93 target. A typical classroom uses a combination of wall panels and ceiling rafts or baffles. A measured acoustic assessment gives the most accurate quantity for a specific room.
What is BB93 and does my school have to comply?
BB93 is the UK Building Bulletin that sets acoustic standards, including maximum reverberation times, for schools. New-build and major refurbishment projects must comply. Existing schools are not always legally required to retrofit to BB93, but it is the benchmark used when improving learning environments, and meeting it generally requires adding absorptive panels.
Should I use wall panels or ceiling panels in a classroom?
Most classrooms benefit from both. Wall panels control reflections at the level where pupils and teachers are speaking and listening, while ceiling rafts or baffles treat a large area from above, which is valuable when walls are full of windows and displays. The best balance depends on the room and is confirmed by an acoustic assessment.
Can acoustic panels be used as display boards too?
Yes. Acoustic pin boards combine sound absorption with a pinnable surface, so they work as both an acoustic panel and a display board. This is especially useful in classrooms where wall space is limited and every surface needs to do more than one job.
