Envirotech Systems Perforated Wooden Acoustic Panel made out of Prelaminated 16 mm Thick high density MDF/HDF Board of density 700-800Kg/m3, The Noise Reduction Coefficient (NRC) is a scalar representation of the amount of sound energy absorbed upon striking a particular surface. An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption. In particular, it is the average of four sound absorption coefficients of the particular surface at frequencies of 250 Hz, 500 Hz, 1000 Hz, and 8000 Hz. These frequencies encompass the fundamental frequencies and first few overtones of typical human speech, and, therefore, the NRC provides a decent and simple quantification of how well the particular surface will absorb the human voice. A more broad frequency range should be considered for applications such as music or controlling mechanical noise. Specifications for materials used in sound absorption commonly include an NRC. Acoustical materials manufacturers often report NRC values higher than 1.0 due to the way the number is calculated in a laboratory. A test material’s area does not include the sides of the panel (which are exposed to the test chamber) which vary due to its thickness. A certain percentage of the sound will be absorbed by the side of the panel due to diffraction effects.

    Perforted Acoustic Panels

    In the realm of acoustic design, Perforated Acoustic Panels stand out as pivotal elements in crafting environments that seamlessly blend visual appeal with refined sound dynamics. These panels, celebrated for their ability to absorb and regulate sound, play a crucial role in constructing spaces that achieve both acoustic harmony and aesthetic sophistication.

    The adoption of Perforated Metal Ceiling solutions is witnessing a surge, especially in commercial and institutional contexts. Beyond enhancing architectural designs, these ceilings significantly elevate acoustic comfort by absorbing unwanted noise. The perforated design facilitates the passage of sound waves for absorption, effectively mitigating echoes and reverberations.

    Equally popular are Perforated Wooden Acoustic Panels, celebrated for their natural aesthetic charm coupled with efficient sound absorption. These panels introduce warmth and organic texture while effectively controlling sound dynamics. Embracing the same principles, Perforated Acoustic Boards and tiles offer versatility in design and application, making them suitable for a range of spaces, from office settings to expansive auditoriums.

    Advancements in metal sound absorption have given rise to Perforated Metal Sound-absorbing Panels. These panels seamlessly integrate durability with acoustic prowess, making them an ideal choice for environments where longevity and style are paramount. Designed with a specific focus on addressing challenging acoustic scenarios, Perforated Metal Acoustic Panels and Wall Panels strike a balance between functionality and visual appeal.

    Micro Perforated Acoustic Panels mark a significant leap in Acoustic Technology. Featuring minute perforations, these panels deliver superior sound absorption capabilities, particularly in environments where precise sound management is imperative. The sleek and nearly seamless appearance of Micro-perforated Panels has made them a preferred choice for designers seeking a minimalist aesthetic.

    Within the realm of more specific materials, Perforated MDF Panels and Perforated Plywood Acoustic Panels bring a fusion of modern design and effective sound control. Renowned for their versatility and ease of customization, these materials seamlessly integrate into various interior design schemes.

    Micro Perforated wooden Panels present another innovative solution, offering the allure of wood with enhanced acoustic properties. Ideal for spaces where the aesthetic appeal of wood is desired without compromising on acoustic performance, these panels marry beauty with functionality.
