Stopping Sound From Bouncing Around a School Hall
Learn how acoustic wall panels, ceiling panels and suspended baffles reduce echo and reverberation in school halls to improve speech clarity and learning outcomes.
Introduction
School halls are among the busiest and most versatile spaces in any educational facility. Throughout the year they host assemblies, performances, indoor sporting activities, examinations, presentations and community events, often accommodating hundreds of students, staff and visitors at the same time.
While these large open spaces are designed to bring people together, they also present one of the biggest acoustic challenges within a school. High ceilings, hard walls, timber floors and expansive glazing allow sound to reflect repeatedly around the room, creating excessive reverberation and making speech difficult to understand.
Poor acoustics don't just create noise—they reduce speech intelligibility, increase vocal strain for teachers and presenters, and make it harder for students to concentrate during important activities.
Fortunately, these problems can usually be resolved with well-designed acoustic treatment. Products such as acoustic wall panels, ceiling panels, suspended rafts and acoustic baffles help absorb reflected sound, creating clearer communication and a more comfortable environment for everyone using the space.
Why Do School Halls Echo?
Most school halls are built using durable, hard materials such as concrete, plasterboard, brick, glass and timber. While these materials are practical and long-lasting, they reflect sound rather than absorb it.
Every spoken word, clap, whistle or musical note bounces between the walls, ceiling and floor before gradually fading away. In larger halls, these reflections overlap with new sounds, creating excessive reverberation and making speech increasingly difficult to understand.
The higher the ceiling and the larger the room, the more pronounced this effect becomes. As student numbers increase, so does the overall noise level, often making the hall uncomfortable for assemblies, performances and sporting events.
Why Good Acoustics Matter in Schools

Good acoustics play an important role in creating effective learning environments.
When students can clearly hear teachers, presenters and performers, they are more likely to remain engaged and retain information. Clear communication also reduces the need for teachers to raise their voices, helping minimise vocal fatigue over time.
Improved acoustics also benefit:
- School assemblies
- Music performances
- Drama productions
- Indoor sporting activities
- Community events
- Examinations
- Parent information sessions
Rather than simply reducing noise, acoustic treatment creates a more functional and inclusive space that supports learning, communication and wellbeing.
How Acoustic Panels Reduce Reverberation
Acoustic panels work by absorbing sound energy instead of allowing it to reflect back into the room.
When sound waves strike an acoustic panel, much of the energy is absorbed within the panel's structure rather than bouncing off hard surfaces. This reduces reverberation, improves speech clarity and lowers overall background noise.
The result is a space where announcements are easier to understand, conversations become clearer and presentations sound more natural.
The effectiveness of an acoustic solution depends on several factors, including the size of the hall, ceiling height, wall construction and the intended use of the space. For this reason, selecting the right combination of acoustic products is essential.
Which Acoustic Products Work Best?
Different school halls require different acoustic solutions. Often, the best results are achieved by combining multiple products.
Acoustic Wall Panels
Wall panels absorb sound reflections travelling horizontally through the room.
They are particularly effective in halls with large uninterrupted wall surfaces and can also be customised with colours, printed graphics or school branding.
Acoustic Ceiling Panels and Rafts
Where wall space is limited, ceiling-mounted acoustic panels or rafts help absorb sound reflecting from above.
These systems are ideal for halls with high ceilings and can significantly reduce reverberation without impacting floor space.
Suspended Acoustic Baffles
Acoustic baffles are suspended vertically from the ceiling, exposing more surface area to absorb sound.
They are particularly effective in school halls with exposed ceilings, sports halls and multipurpose spaces where conventional ceiling systems may not be practical.
Because they combine strong acoustic performance with architectural flexibility, baffles are one of the most popular solutions for large-volume spaces.
How Much Acoustic Treatment Does a School Hall Need?

There is no universal answer.
The amount of acoustic treatment required depends on factors including:
- Room dimensions
- Ceiling height
- Existing finishes
- Number of occupants
- Intended activities
- Performance targets
Installing too few panels may have little noticeable impact, while excessive treatment can create an unnaturally "dead" sounding room.
An appropriate acoustic assessment ensures the right balance between speech clarity and natural room ambience.
Understanding Reverberation Time
Reverberation time measures how long sound continues to linger after its source has stopped.
For educational environments, lower reverberation times generally improve speech intelligibility and create better listening conditions.
Australian Standard AS/NZS 2107 provides guidance for acceptable internal noise levels and acoustic performance within educational buildings.
For new school projects and major refurbishments, acoustic consultants often use reverberation time targets to determine the quantity and placement of acoustic treatment required.
Fire Performance for School Buildings
When specifying acoustic products for education projects, fire performance is an essential consideration.
Products should comply with the relevant requirements of the National Construction Code and applicable Australian Standards.
Acoustic Panels Australia's range includes products with tested fire performance suitable for commercial and education environments, helping architects and builders meet project compliance requirements.
Common Mistakes When Treating School Hall Acoustics
Some of the most common mistakes include:
- Installing too few panels
- Treating only one surface
- Ignoring ceiling reflections
- Choosing products based solely on appearance
- Not considering reverberation time
- Selecting products without suitable fire performance
A properly designed acoustic solution considers the room as a whole rather than relying on isolated treatments.
Choosing the Right Acoustic Solution
Every school hall is different.
Some projects benefit primarily from wall-mounted acoustic panels, while others require suspended ceiling rafts or acoustic baffles to achieve the desired performance.
Large multipurpose halls often use a combination of wall panels, ceiling panels and suspended baffles to create balanced sound absorption throughout the space.
The most effective solution depends on the hall's size, construction, intended use and acoustic performance objectives.
