Well designed classrooms are more than just desks, chairs, a blackboard and a teacher.

They’re an environment where every child should be able to hear, focus, and learn without unwanted distractions.

Classroom acoustics refers to how sound behaves within a learning space, including both background noise and reverberations (echoes).

Good acoustics help teachers and students to communicate clearly, whilst poor acoustics lead to missed information, increased frustration, and impaired learning.

In the chapters below, we explore why controlling sound in classrooms is so important to education, and how excess noise affects learning and impacts the lives of young people.

We explore legislative and practical factors, and reveal effective treatments for improving classroom acoustics.

Why Classrooms Need Acoustic Treatment

Classrooms can be frantic and highly active spaces, with lots going on all at once.

Conversations between pupils and teachers mix with external sounds from adjoining classrooms, nearby corridors, outdoor playgrounds, and road noise.

Without appropriate acoustical control, this mix of airborne sound builds up, causing echoes to reduce speech clarity and educational learning.

Acoustic treatment is essential because children, especially younger pupils, are still developing language and listening skills.

If the sound environment is poor, pupils are far more likely to misunderstand what’s being taught, thus becoming distracted, struggling with even the most basic tasks that require concentration.

This can be especially damaging to pupils with impaired hearing or learning difficulties.

Impact of Noise on Childhood Cognitive Development

Speech Intelligibility

Children cannot process speech as effectively as adults, particularly in noisy or echoey rooms.

If speech intelligibility is low, pupils have to concentrate more to understand what’s being said, which leads to mental fatigue and reduced learning.

Research suggests that in poor acoustic environments, children miss up to a quarter of the words spoken by their teacher.

This can have a huge impact on their overall education level and exam results.

Attention and Concentration

Maintaining focus and concentration is crucial for learning in classroom settings.

Excess noise, whether from within the classroom or an adjoining space, grapples with the teacher’s voice, making it harder for students to stay interested or engaged.

Over time, this continuous mental effort to filter sound becomes mentally exhausting, reducing a  child’s ability to concentrate and absorb information.

Inclusivity

Good classroom acoustics are essential for inclusive learning.

Pupils with impaired hearing, cochlear implants, autism spectrum conditions, or English as an additional language benefit greatly from quieter, more controlled sound environments.

Without calm and serene learning conditions, these students are especially at risk from being left behind academically as well as socially.

Key Considerations

School Building Regulations

In the UK, Building Bulletin 93 (BB93) sets out acoustic performance standards for schools.

These regulations include limits for reverberation times, sound insulation between rooms, and permissible background noise levels.

Any proposed acoustic treatment plan should comply with these standards to meet both legal requirements and best practices.

Existing Room Furnishings

Solid surfaces such as desks, chairs, floors, and the existing decor all affect how sound travels.

Bare walls, hard floors, and minimal soft furnishings create reflective surfaces leading to amplification and reverberation.

So before investing in specialist soundproofing products, it’s worth assessing whether simple changes like adding more absorbent surfaces and softer furnishings, cork boards, drapes or even blinds could make a difference.

Existing Walls Structure and Thickness

The construction of internal and external walls has a major impact on sound transmission.

Lightweight or hollow stud walls allow noise to pass between rooms more easily, while solid masonry walls offer better sound isolation.

Understanding the wall structure helps in choosing the right acoustic treatment.

Special Education Needs (SEN)

For students with special needs, especially those with auditory processing disorders or heightened sound sensitivity, acoustic quality has a profound effect on comfort and learning.

In SEN classrooms, enhanced acoustic treatment is often necessary to create a calmer and more predictable sound environment.

Nearby and Adjoining Rooms

Noise from adjacent spaces such as music rooms, sports halls, or busy corridors can easily penetrate classrooms without proper sound insulation.

Location-specific considerations should form part of the treatment strategy.

Ways to Improve Classroom Acoustics

Absorbers and Diffusers

Acoustic absorbers reduce the amount of sound energy reflected around a room, while diffusers scatter sound waves to reduce hotspots of loudness or dead spots.

A balanced combination ensures speech clarity while avoiding an overly “dead” sound.

Ceiling Panels

The ceiling can be one of the most important surfaces for acoustic treatment in a classroom.

Installing high-quality ceiling panels helps absorb overhead sound reflections, significantly improving speech clarity.

Acoustiblok’s AcoustiCloud Acoustic Ceiling Panels are designed to be lightweight, effective, and aesthetically discreet.

They not only absorb excess noise but also contribute to a more comfortable educational environment.

Wall Coverings

Hard, reflective walls can be a major source of echoes.

Similarly for walls, Acoustiblok’s AcoustiWall Acoustic Wall Panels can be used alongside ceiling treatments to target key reflection points.

Specialist wall coverings with absorptive properties can greatly improve the acoustic comfort of a classroom.

Cork boards, pin boards and notice boards can be a very useful and practical way of introducing absorptive surfaces to reduce reflections.

Acoustiblok Wallcover is a high-performance option designed to block and dampen sound transmission through existing walls without requiring full reconstruction.

It’s particularly useful in schools where budget or building restrictions limit major structural changes.

Soft Surfaces

Adding carpets, rugs, or cushioned flooring where practical within the specific environments can help reduce impact noise, foot fall and absorb some of the room’s airborne sound.

While not a silver bullet solution, soft finishes complement other acoustic treatments and improve overall comfort.

Curtains and Fabrics

Thick, heavy curtains over windows help reduce sound reflections and block unwanted external noise.

Fabric wall hangings, upholstered notice boards, and soft furnishings all contribute towards an acoustically softer environment.

Final Thoughts

Classroom acoustics are not just a matter of comfort, they are central to effective education and learning.

By controlling noise levels and reducing echoes, schools can ensure that every pupil hears clearly, stays engaged, and enjoys a fair chance to succeed.

From meeting BB93 standards to using proven soundproofing solutions by Acoustiblok, the right approach to acoustic treatment can transform a noisy, distracting classroom into a focused, inclusive learning environment.
