Acoustic sound-absorbing foam panel – 300×300×50 mm, smooth, with bevelled edges, black
Acoustic foam panel with a smooth central surface and bevelled edges 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.
A wide smooth surface is formed in the centre of the panel and surrounded by bevelled edges. This profile creates a restrained, neat acoustic finish and allows the panels to be joined into a continuous modular composition. 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 a minimalist 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.
The wide central surface absorbs part of the sound energy entering the panel directly, while the bevelled edges create zones oriented at different angles. These may help soften some sound reflections returning from the wall or ceiling.
The actual acoustic result depends on the area covered with foam, room size, wall and ceiling materials, furniture, panel arrangement, installation location, air gap 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.Smooth surface with bevelled edges
The panel surface features a wide, smooth central section surrounded on all four sides by a bevelled border. This geometry gives the panel the appearance of a recessed square segment or a soft acoustic frame.
- creates a neat and minimalist acoustic-finishing surface;
- the bevelled edges create surface zones at different angles;
- helps reduce the effect of a completely flat wall surface;
- the panels can be joined into a regular square grid;
- the shape suits modern and understated interiors;
- suitable for decorative acoustic wall and ceiling finishing.
Shape description:
The surface of this panel may be described as smooth with bevelled edges, recessed-centre profile, frame-shaped relief or with a bevelled perimeter border.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 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 or test standard. Therefore, it is not possible to specify precisely how much 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, minimalist and technical interiors.

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. The smooth central surface and bevelled edges create a restrained, modular acoustic-finishing profile.
The 300×300×50 mm foam modules can be installed on walls or ceilings, joined into larger regular 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.
