Acoustic sound-absorbing foam panel – 300×300×50 mm, combined geometric relief, black
Acoustic foam panel with a dense combined geometric relief is intended to reduce echo, reverberation and some unwanted sound reflections in a room. The panel is made of sound-absorbing polyurethane foam, commonly referred to as foam rubber.
The surface combines repeating curved recesses, vertical ribs and angular V-shaped zones. This structure increases the active foam surface area and creates many planes of different depths and angles, helping to absorb and disperse sound waves reflected from walls or ceilings. Panel dimensions: 300×300 mm, total thickness: 50 mm.
Important information about the intended use:
Acoustic foam is primarily intended to improve the internal acoustics of a room by reducing echo, reverberation and some sound reflections. On its own, it does not provide complete sound insulation between rooms and does not replace an airtight, massive and multilayer sound-insulating structure.Important information about flammability:
The supplied information describes the foam as flame-retardant or slower-burning, but no specific reaction-to-fire class, test standard or certificate is stated. Where a project includes fire-safety requirements, the test documentation for the specific product must be checked.Main purpose:
The panel is installed on walls or ceilings when it is necessary to reduce room echo, soften sound reflections from hard surfaces, improve speech or recording clarity and create an expressive decorative acoustic surface.Panel size

When sound waves enter the open-cell structure of polyurethane foam, part of their energy is attenuated inside the material. As air particles move between the pores, part of the acoustic energy is converted into a small amount of heat through friction.
Curved recesses, raised ribs and angular surface zones create many planes of different depths and directions. As a result, some sound waves penetrate deeper into the foam structure, while others are dispersed in different directions at the ribs and profile edges.
The actual acoustic result depends on the area covered with foam, room size, wall and ceiling materials, furniture, panel arrangement, installation location, air gap, foam density and sound frequency.
Sound absorption and sound insulation are not the same:
Acoustic foam reduces sound reflections inside a room, but it does not block all sound transmission through a wall. Sound insulation requires airtight, massive and properly designed wall, ceiling or floor structures.Combined geometric-relief surface
The panel surface features a densely repeating relief combining curved recesses, higher dividing ribs and angular V-shaped zones. The surface resembles interconnected acoustic cells.
- increases the active sound-absorbing surface area of the foam;
- creates numerous surface zones of different depths and shapes;
- helps disperse some sound waves returning from walls or ceilings;
- reduces direct reflections from smooth, hard surfaces;
- creates a dense and expressive decorative pattern;
- suitable for modular acoustic wall and ceiling finishing.
Shape description:
The surface of this panel may be described as combined geometric relief, dense cellular profile, with curved recesses and V-shaped ribs or segmented acoustic relief.Curved recesses and angular ribs
Each repeating relief segment consists of a curved concave zone bordered on the sides by higher foam ribs. Angular and V-shaped recesses form between the segments.
The curved surface sections help avoid exclusively flat, parallel surfaces, while the segment edges and ribs create more points from which some sound waves are redirected in different directions.
This profile can be used not only for acoustic purposes but also as a distinctive geometric decorative element for walls or ceilings.
50 mm thick acoustic foam
The total panel thickness is 50 mm. This foam thickness provides a greater volume of sound-absorbing material than thinner acoustic panels and may be more suitable when room echo and sound reflections need to be reduced more effectively.
The 50 mm panel projects further from the wall, but the greater material depth generally allows it to work across a broader frequency range than a very thin foam layer. The actual effect depends on foam density, pore structure, surface profile and installation method.
Installing the panel with an air gap between the wall and the foam may improve absorption in part of the lower-frequency range. The exact result must be assessed in relation to the overall acoustic design of the room.
Acoustic performance:
The supplied specification does not state a sound absorption coefficient, NRC, αw, foam density or test standard. Therefore, it is not possible to specify precisely what proportion of sound the foam absorbs in individual frequency ranges.Polyurethane foam construction
The panel is made of flexible polyurethane foam. It is a lightweight, elastic and easy-to-process material that can be adapted to different wall and ceiling surfaces.
- open-cell structure for absorbing part of the sound energy;
- total sound-absorbing material thickness of 50 mm;
- low weight and easier fastening;
- flexible and easy-to-cut material;
- suitable for acoustic wall and ceiling finishing;
- can be used as a soft protective foam material;
- the black colour suits studio, modern and technical interiors.

Practical usage example
For example, in a small recording or broadcasting room, strong reflections from empty walls may be clearly audible when speaking. Combined geometric-relief foam panels are installed behind the microphone, on side walls or at other first-reflection points.
When sound waves reach the curved recesses, higher ribs and angular profile sections, part of their energy enters the foam structure and is attenuated, while part is dispersed in different directions.
The best result is usually achieved not by using a single panel, but by strategically covering a larger wall or ceiling area.
Calculating the required quantity
The area of one 300×300 mm foam panel is 0.09 m². To cover a theoretical area of 1 m², approximately 11.1 panels would be required, so in practice it is recommended to calculate 12 panels per square metre, excluding cutting and installation losses.

The acoustic foam panel is intended to absorb part of the sound travelling through a room and reduce reflections from walls and ceilings. Curved recesses, angular ribs and repeating cellular segments create a dense acoustic surface with varying depths.
The 300×300×50 mm foam modules can be installed on walls or ceilings, combined into larger decorative compositions and cut to suit the shape of the room when required.
The 50 mm layer of polyurethane foam provides a greater volume of sound-absorbing material. The panels are suitable for home studios, offices, broadcasting, gaming, teaching and other dry indoor spaces.
Acoustic foam improves the internal acoustics of a room but is not a complete sound-insulation system. For precise acoustic or fire-safety design, the sound absorption and reaction-to-fire test documentation must be checked.
