Project Type: Educational Facility / Classroom
Acoustic Products: Polyester Fiber Acoustic Panels + Aluminum Frames
Application: Classroom Acoustic Treatment / Speech Intelligibility / Reverberation Control
Scope: Custom Acoustic Products + Technical Support

Classrooms need to support clear communication. When sound reflects excessively from hard walls, ceilings, floors, and other surfaces, speech can become less distinct and background noise can be more noticeable.
For this educational project, the acoustic treatment was designed to improve the room’s acoustic environment while maintaining a clean, colorful interior suitable for a modern learning space.
ES Acoustic supplied custom polyester fiber acoustic panels with aluminum frames, together with suspended acoustic treatment for the ceiling. The combination provides sound absorption at key reflection areas while allowing the acoustic elements to become part of the classroom’s interior design.
Classrooms can contain many acoustically reflective surfaces, including painted walls, glazing, hard ceilings, flooring, desks, and other furniture.
When sound reflections build up in the room, students may have more difficulty following speech, particularly when several people are speaking or when background noise is present.
The project therefore required an acoustic treatment that could:
Rather than treating the entire room with one type of acoustic product, the acoustic elements were positioned across walls and ceiling areas to provide more targeted sound absorption.
The main wall treatment uses polyester fiber acoustic panels mounted within custom aluminum frames.
This construction combines a lightweight sound-absorbing panel with a rigid architectural frame, creating a clean and structured appearance suitable for educational interiors.
The framed configuration also provides flexibility for large wall installations, where consistent panel alignment and a neat finished edge are important.


Polyester fiber acoustic panels are widely used for interior acoustic treatment because they can provide sound absorption while offering flexibility in shape, size, color, and surface design.
For educational spaces, the material can be customized to create acoustic treatment that works visually with the surrounding architecture rather than appearing as a purely technical addition.
Depending on the project requirements, panel dimensions, thickness, colors, and edge details can be customized.
Acoustic treatment does not have to look industrial.
For this project, the wall panels use a combination of yellow and grey tones, creating a visual feature while maintaining a clean architectural appearance.
Using different panel colors can also help designers divide large wall surfaces into visually organized sections.
Custom color options allow acoustic panels to be coordinated with:
For projects with specific design requirements, custom colors and panel configurations can be developed according to the interior design concept.
The framed polyester fiber panels are installed across selected wall areas to introduce sound-absorbing surfaces into the classroom.
This helps reduce the amount of sound energy reflected from otherwise hard wall surfaces.
The exact quantity and placement of acoustic panels should be determined according to the room geometry, existing finishes, occupancy, and acoustic requirements.
For larger educational spaces, wall-mounted absorption can be combined with ceiling treatment to distribute the acoustic treatment more effectively throughout the room.
In addition to the wall panels, suspended acoustic elements can be used to introduce additional absorption into the ceiling zone.
Ceiling-mounted acoustic treatment is particularly useful when the existing ceiling contains large reflective surfaces or when additional treatment is required without covering the entire ceiling.
Suspended acoustic baffles or clouds can be configured around existing lighting, HVAC, and other building services.
This allows acoustic treatment to be integrated into the existing ceiling environment while maintaining access to building services where required.

For schools and educational facilities, acoustic performance is only one part of the specification.
The acoustic system also needs to be practical for installation, visually appropriate, and suitable for long-term use.
The aluminum-framed polyester fiber system offers several advantages for project applications:
Clean Architectural Appearance
The aluminum frame creates a defined perimeter and consistent panel alignment.
Custom Dimensions
Panel sizes and layouts can be developed around the actual wall dimensions.
Flexible Colors
Polyester fiber surfaces are available in a wide range of colors for architectural coordination.
Targeted Acoustic Treatment
Panels can be positioned at selected reflection areas rather than relying on a uniform wall covering.
Easy Project Coordination
Framed panels can be detailed around doors, windows, columns, lighting, and other architectural elements.
A successful classroom acoustic project requires more than selecting a panel with a high NRC rating.
The acoustic treatment should be considered in relation to the room volume, surface finishes, occupancy, ceiling height, existing reverberation, and intended use.
Depending on the project requirements, our technical team can support:
For projects where an acoustic consultant is already involved, we can also manufacture the acoustic products according to the consultant’s specifications and drawings.
This classroom project demonstrates how acoustic treatment can combine sound absorption, architectural design, and practical installation.
The use of polyester fiber panels with aluminum frames provides a flexible solution for wall applications, while suspended ceiling treatment can add further acoustic absorption where required.
For classrooms, lecture rooms, science labs, libraries, training centers, and other educational environments, ES Acoustic can develop custom acoustic treatment around the project’s acoustic requirements, interior design, and construction conditions.
