Key advantages
- Effective sound absorption to improve acoustics and reduce sound reflections in the space
- Deep three-dimensional structure that increases the surface area exposed to sound waves
- Suitable for targeted acoustic treatment as part of an overall sound absorption system
- Lightweight thanks to a material density of approx. 19 kg/m³
- Flexible, easy-to-process material, allowing acoustic elements to be produced in various shapes
- Low thermal conductivity of 0.040 W/(m·K)
Why this product
The open, porous structure of the foam allows sound waves to penetrate the material, where they are gradually absorbed instead of bouncing back into the space as reflections. In this way, the product helps reduce sound reflections and reverberation, creating a more pleasant and balanced acoustic environment.
Technical description
An acoustic bass trap made from flexible open-cell polyurethane foam in anthracite, with a density of 19 ± 1 kg/m³. It is produced as a three-dimensional unit with a deep profile, measuring 550 × 360 × 360 mm, and is designed for sound absorption in interior spaces.
Applications
Designed to be placed in areas of a room where you want to increase sound absorption, particularly in corners and where walls meet. It is used to reduce low-frequency build-up, minimise sound reflections and reverberation, and improve the balance and clarity of sound in the room.
Particularly suitable for spaces with bass or reverberation problems, such as recording studios, music rooms, rehearsal rooms, listening rooms and spaces with audio systems, as well as for noise absorption in buildings and industrial environments, including electrical equipment cabinets and enclosures.
