    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 relief, densely ribbed 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. 

  • Product description

    Acoustic sound-absorbing foam panel – 300×300×50 mm, relief, densely ribbed, 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 relief, densely ribbed 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, reverberation and some sound reflections. On its own, it does not provide complete sound insulation between rooms and does not replace a multilayer sound-insulating wall, ceiling or floor 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 documentation for the specific product must be checked.
    Main purpose:
    The acoustic foam panel is installed on walls or ceilings when it is necessary to reduce room echo, soften sound reflections, improve speech or recording clarity and create a black decorative acoustic surface.

    Acoustic operating principle

    When sound waves enter the open-cell structure of polyurethane foam, part of the sound energy is attenuated inside the material. As air particles move between the pores, part of the acoustic energy is converted into thermal energy through friction.

    The dense longitudinal ribs increase the total active surface area of the foam and create zones of different depths. As a result, some of the sound waves travelling from the wall or ceiling are absorbed, while some are dispersed in different directions.

    The actual result depends on the area covered with foam, the room size, wall and ceiling materials, furniture, panel installation location, distance from the wall 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 walls. Sound insulation requires airtight, massive and properly designed structures.

    Relief, densely ribbed surface

    Dense, parallel longitudinal ribs and grooves are formed on the panel surface. This fine profile creates a larger active surface area than a flat foam panel.

    • 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 dense, rhythmic geometric pattern;
    • allows the panels to be installed vertically, horizontally or with alternating orientation;
    • suitable for decorative acoustic wall and ceiling compositions.

    50 mm thick acoustic foam

    The panel thickness is 50 mm. A thicker foam layer provides a greater volume of sound-absorbing material than a 25 mm panel and may be more suitable where room echo and sound reflections need to be reduced more effectively.

    The 50 mm foam projects further from the wall, but its greater material depth may allow it to work across a broader frequency range than a thinner panel with the same profile. The actual result depends on the foam density, pore structure, installation method and room characteristics.

    Installing the panel with an air gap between the wall and the foam may improve absorption in part of the lower-frequency range, but the exact effect 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 a particular frequency range.

    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;
    • 50 mm layer of sound-absorbing material;
    • low weight;
    • flexible and easy-to-cut material;
    • suitable for wall and ceiling finishing;
    • can be used as a soft protective foam insert;
    • the black colour suits studio 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.

    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

    Installation methods

    Quick selection guide

    Choose the relief, densely ribbed 50 mm acoustic foam panel when you need to reduce some room echo and sound reflections and a thicker foam layer is more important than minimising how far the finish projects from the wall.

    FAQ – frequently asked questions

    Is this a foam panel?
    Yes. The panel is made of polyurethane foam, a material commonly referred to as foam rubber in everyday and commercial use.
    How can its surface be described?
    The surface may be described as relief, densely ribbed, finely profiled or as having longitudinal ribs and grooves.
    What are the panel dimensions?
    One foam panel measures 300×300 mm and is 50 mm thick.
    How does the 50 mm panel differ from the 25 mm panel?
    The 50 mm panel contains a greater volume of sound-absorbing material. It projects further from the wall, but may be more suitable where the aim is to reduce room echo and sound reflections more effectively.
    Does foam completely insulate sound?
    No. Acoustic foam improves the acoustics inside a room but is not a complete sound-insulation system between rooms.
    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 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 50 mm 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.

    Relief, densely ribbed 50 mm acoustic foam for reducing room echo

    The acoustic foam panel is intended to absorb part of the sound travelling through a room and reduce reflections from walls and ceilings. The dense longitudinal ribs increase the active absorption area and help 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.

    The 50 mm layer of polyurethane foam provides a greater volume of sound-absorbing material than a 25 mm panel with the same profile. It is suitable for 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.
