  • Acoustic sound-absorbing foam panel – 300×300×25 mm, finely 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 finely profiled foam surface with dense longitudinal ribs 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: 25 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.

    Finely profiled foam surface

    Dense, parallel longitudinal ribs and grooves are formed on the panel surface. Compared with acoustic foam with a coarser profile, this panel has a finer and denser surface pattern.

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

    25 mm thick acoustic foam

    The panel thickness is 25 mm. A foam panel of this thickness is primarily suitable for reducing some mid- and higher-frequency sound reflections, softening speech echo and improving acoustic comfort in the room.

    The 25 mm panel is thinner and projects less from the wall than 50 mm foam, making it suitable where compact installation and a low overall finishing thickness are important.

    Low-frequency absorption may be limited. It can be improved to some extent by installing the foam with an air gap, but the exact result depends on the overall room structure.

    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;
    • low weight;
    • flexible and easy-to-cut material;
    • compact overall thickness of 25 mm;
    • suitable for wall and ceiling finishing;
    • can be used as a soft protective foam insert;
    • the black colour suits studio and technical interiors.

    Where is it used?

    • In home studios — to reduce echo in voice and music recordings.
    • In broadcasting rooms — to reduce reflections captured by the microphone.
    • In gaming rooms — to improve speech and sound clarity.
    • In offices — to improve acoustic comfort in the room.
    • In meeting rooms — to reduce the perception of reverberation.
    • In home cinema rooms — to control some sound reflections.
    • In rehearsal rooms — to reduce mid- and higher-frequency reflections.
    • In technical rooms — to absorb some sound reflections from equipment.
    • In teaching and language classrooms — to improve speech clarity.
    • In equipment cases and packaging — as soft protective foam.

    Practical usage example

    For example, in a small office or broadcasting room, strong reflections from empty walls may be clearly audible when speaking. Foam panels are installed behind the microphone, on the side walls or at other first-reflection points.

    The densely profiled surface helps reduce the intensity of sound waves returning from a hard wall. As a result, the microphone may capture less pronounced room echo and speech may sound clearer.

    The best result is achieved by covering a strategically selected total wall or ceiling area rather than a single isolated spot.

    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

    Mechanical fastening

    • the foam can be secured with pins, small nails or staples;
    • suitable for wooden or other softer substrates;
    • the panels can be removed or repositioned more easily;
    • no adhesive layer is required;
    • the fastening elements must not tear the foam.

    Adhesive installation

    • use adhesive suitable for polyurethane foam;
    • the substrate must be dry, clean and stable;

    Finely profiled 25 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 dense longitudinal ribs increase the active absorption area and help disperse sound waves.

    The 300×300×25 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, broadcasting, gaming, teaching 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.
