  • Acoustic | Sound-Absorbing Foam Panel | 300x300x50mm | Black

    Code: ES-SJC6-335

    Acoustic foam panel is designed to reduce echo, reverberation, and some unwanted sound reflections within a room. The panel is made of sound-absorbing polyurethane foam, commonly known as acoustic foam.

    The profiled foam surface increases the effective sound-absorbing area and helps disperse sound waves reflected from walls or ceilings. The panel dimensions are 300 × 300 mm, with a thickness of 50 mm. 

  • Acoustic sound-absorbing foam panel – 300×300×50 mm, profiled, black

    Acoustic foam panel is intended to reduce echo, reverberation and some unwanted sound reflections occurring in a room. The panel is made of sound-absorbing polyurethane foam, commonly referred to as foam rubber.

    The profiled foam surface increases the active area of the sound-absorbing material and helps disperse sound waves reflected from walls or ceilings. Panel dimensions: 300×300 mm, 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 and sound reflections. On its own, it does not provide complete sound insulation between adjacent rooms and does not replace a multilayer sound-insulating wall 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. For use in a designed project, these properties must be checked against the documentation for the specific product.
    Main purpose:
    Acoustic foam is installed on walls or ceilings when it is necessary to reduce the perception of echo, improve speech clarity, soften sound reflections or create a decorative acoustic surface.

    Acoustic operating principle

    When sound waves enter the open-cell structure of polyurethane foam, part of the sound energy is attenuated within the material. As the sound energy moves between the pores, part of it is converted into thermal energy.

    The relief surface of the acoustic foam increases the material’s total active area and creates zones of different depths. As a result, some sound waves are not only absorbed but also dispersed in different directions.

    The actual acoustic result depends on the surface area covered with foam panels, the room size, wall and ceiling materials, furniture, panel thickness, installation location 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 generally requires massive, airtight and multilayer structures.

    Profiled foam surface

    Parallel raised and recessed foam strips are formed on the surface of the panel. This profile creates more varied sound-reflection angles than a flat surface.

    • increases the active sound-absorbing surface area of the foam;
    • helps disperse some sound reflections;
    • reduces the effect of a smooth, hard wall surface;
    • creates a rhythmic geometric pattern;
    • allows the panels to be installed in one direction or with alternating orientation;
    • can be used for decorative acoustic compositions.

    50 mm thick acoustic foam

    The panel thickness is 50 mm. A thicker layer of acoustic foam generally absorbs a broader frequency range than very thin decorative foam, but the actual effectiveness depends on the foam density, pore structure and installation method.

    Installing the foam panel with an air gap between the wall and the material may improve absorption in part of the lower-frequency range. The exact result depends on 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 each frequency range.

    Polyurethane foam construction

    The panel is made of flexible polyurethane foam. It is a lightweight, elastic and easy-to-process material suitable for different wall and ceiling surfaces.

    • open-cell structure for absorbing sound energy;
    • low weight;
    • flexible and easy-to-cut material;
    • can be adapted to corners and edges;
    • suitable for wall and ceiling finishing;
    • can be used as a soft protective foam insert;
    • the black colour suits technical and studio-style 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 foam panels per square metre, excluding cutting and installation losses.

    Number of panels Approximate coverage area
    1 pc. 0.09 m²
    6 pcs. 0.54 m²
    12 pcs. 1.08 m²
    24 pcs. 2.16 m²
    48 pcs. 4.32 m²

    What is acoustic foam used for?
    It is intended to absorb part of the sound energy, reduce room echo and reverberation, and provide acoustic finishing for walls or ceilings.
    Does foam completely insulate sound?
    No. Acoustic foam improves the acoustics inside a room but is not a complete sound-insulation system between rooms.

    One foam panel measures 300×300 mm and is 50 mm thick.
    How many panels are needed for 1 m²?
    In practice, it is recommended to allow approximately 12 foam panels per square metre.
    Can the foam be cut?
    Yes. Polyurethane foam can be cut with a sharp knife using a straight ruler.
    Can the foam be glued?
    Yes, but an adhesive specifically suitable for polyurethane foam must be used. It must not dissolve or deform the material.
    Can it be installed on a ceiling?
    Yes, but the foam panels must be secured using reliable adhesive or suitable mechanical fasteners.
    Is the foam fire-resistant?
    The supplied information describes it as flame-retardant, but no specific reaction-to-fire class or certificate is stated.
    How should acoustic foam be cleaned?

    Profiled 50 mm acoustic foam for reducing room echo and sound reflections

    The acoustic foam panel is intended to absorb part of the sound travelling through a room and reduce reflections from walls and ceilings. The profiled surface increases the active absorption area and helps disperse sound waves.

    The 300×300×50 mm foam modules can be installed on walls or ceilings, combined into larger arrangements and cut to suit the shape of the room when required.

    Black polyurethane foam is suitable for home studios, offices, rehearsal rooms, gaming rooms, streaming areas and other dry indoor spaces where echo needs to be reduced and speech or sound clarity improved.

    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.
