Sound absorption for walls - PES Circle wall

SilentDirect PES Circle Wall – a round wall-mounted sound absorber offering effective sound absorption and a modern design

SilentDirect PES Circle Wall is a round wall-mounted sound absorber that combines effective sound absorption with a soft and modern design. With its 50 mm thick core of needle-punched polyester, it reduces reverberation and disruptive sound reflections from wall surfaces, while also serving as a decorative interior detail in the room. The circular shape provides a softer visual appearance than traditional rectangular wall absorbers, making the product particularly appealing in environments where both acoustics and design are key elements of the overall aesthetic.

SilentDirect PES Circle Wall is available in three sizes—600 mm, 800 mm, and 1000 mm—as well as in white, gray, and black. This makes it easy to tailor the solution to the room’s size, interior design, and acoustic needs. The product works just as well as a single sound absorber on the wall as it does in larger combinations where several circles are used together to create a more dynamic and thoughtful look.

Effective sound absorption for a better acoustic environment

SilentDirect PES Circle Wall is designed to reduce reverberation and dampen the sound reflections that otherwise occur when sound bounces off hard wall surfaces. When the sound level in a room becomes too high or the reverberation too long, comfort, speech intelligibility, and concentration are all affected. By absorbing some of the sound energy, this wall absorber contributes to a quieter and more balanced acoustic environment.

This makes the product particularly useful in open-plan offices, conference rooms, classrooms, waiting rooms, studios, and home environments where acoustic comfort needs to be improved. In homes, it can be used in living rooms, bedrooms, and home offices to create softer acoustics. In public spaces, it helps ensure clearer speech and a more comfortable sound level throughout the day.

Hypoallergenic and safe material

Just like the other products in SilentDirect’s PES series, PES Circle Wall is made from OEKO-TEX®-certified polyester. The material is free from emissions, allergens, and strong odors, making the product a safe choice in environments with high standards for indoor air quality and user safety.

The material is also moisture- and mold-resistant, meaning the absorbent retains its properties over time even in environments where humidity levels may vary. The needle-punched surface is easy to keep clean and requires minimal maintenance, making the product suitable for both private and public environments where easy care is a key advantage.

Round design that creates a softer look

One of the clearest advantages of SilentDirect PES Circle Wall is its round shape. It differs from more traditional wall absorbers and helps create a softer, more vibrant, and more architecturally expressive look on the wall. The shape allows the absorber to function both as an acoustic solution and as a deliberate part of the interior design.

You can choose to use a single absorber as a discreet focal point or combine several circles in different sizes and colors to create a more creative wall pattern. The colors white, gray, and black make it easy to adapt the product to both modern and classic interiors. This makes SilentDirect PES Circle Wall a strong choice in environments where design must work in harmony with function.

Flexible mounting options

SilentDirect PES Circle Wall can be ordered with two different mounting solutions depending on how the product is to be installed and the desired look in the room.

Without mounting accessories
This option gives you complete freedom to choose your own mounting method, such as using adhesive or screws, depending on the wall’s construction and the project’s requirements.

With hidden mounting brackets
The product comes with 4 CNC-milled keyhole brackets made of MDF, which are permanently glued to the back with solvent-free adhesive. This provides a stable and discreet installation without visible details, enhancing the clean and refined look on the wall.

The hidden mounting brackets make it easier to create a professional installation where the focus is on the absorber’s shape and placement rather than on the mounting itself. This is a clear advantage in environments where the overall impression is important.

Durable construction with a long service life

SilentDirect PES Circle Wall is made from at least 50% recycled polyester from PET bottles. The material can be recycled again, making the product a more sustainable choice for projects where both function and environmental considerations are important. The robust construction ensures that the absorber retains both its shape and its sound-absorbing function over the long term.

This is particularly valuable in environments where the products are used daily and where durability is a key factor. By combining recycled material, good dimensional stability, and a long service life, SilentDirect PES Circle Wall becomes an acoustic solution that is both practical and sustainable.

A sound absorber that combines acoustics and aesthetics

SilentDirect PES Circle Wall is designed for those who want to improve acoustics without compromising the room’s visual appeal. The circular shape, three sizes, and three neutral colors make the product easy to use in many different types of interiors. At the same time, the 50 mm thick polyester core provides effective sound absorption that contributes to greater comfort and well-being in the room.

For those seeking a wall-mounted sound absorber that is functional, durable, and thoughtfully designed, SilentDirect PES Circle Wall is a strong choice. It improves the acoustic environment, adds visual character, and works equally well in homes as well as in professional and public settings.

Acoustic Test: Before and After with PES Sound Absorbers

The test was conducted in a 24 m² studio measuring 4 x 6 meters. A total of 4.026 m² of SilentDirect PES sound absorbers were installed in the room, corresponding to approximately 16.8% of the floor area. The absorbers were placed on both the ceiling and walls to reduce echo, reverberation, and harsh sound reflections.

Products in the test:
1 SilentDirect PES Ceiling, 800 x 800 mm
2 SilentDirect PES Wall, 800 x 800 mm
6 SilentDirect PES Wall, 592 x 592 mm
