Envirotech Micro Perforated Wooden Acoustic Panel provides the best NRC value and aesthetically pleasing look for Walls and Ceilings. The Micro Perforated wooden Acoustic panel has a Perforation design as per acoustic design for controlling the sound reverberation and echo. Envirotech Micro Perforated Acoustic Panels are high-performance acoustical products with an exceptional visual appearance. Micro-Perforated Acoustical panels come in a variety of configurations to meet all interior and acoustical requirements and provide balanced sound reflection and absorption through Acoustically designed perforations. To increase sound absorption value infilled with 50mm thick Rockwool 48kg/m3 density as per Acoustic design.
The Micro Perforated Wooden Acoustic Panels are made of high-density pre-laminated MDF boards, all joints of the wooden acoustic panel have Tongue and Groove Systems or dowel connection to avoid any sagging /unevenness for walls, and ceiling panels have a square edge, Micro Look and Tapered Edge over T grid or T24 Grid Systems. The reverse side of each Micro Perforated acoustic panel is covered with a layer of black acoustic fleece. Micro-Perforated Wooden Acoustic Panel to be Installed over the wall with an aluminum keel with butterfly clip or 1mm thick GI sheet ‘Z” clamps as per the site condition or approval of site in charge.
Variety of pre-laminated board shades with Matt finish, Melamine Glossy Finish. Having 50+ color options available. Thansau maple, Intal Beach, Mangfall Beech, Bavarian Beech, Natural Teak, Khaya Mahogany, Siam wood, Elegant Teak, and Oxford Cherry are some ready stock panels.
Envirotech Micro Perforated Wooden Acoustic Panel made out of Pre-laminated 11 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 broader 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.
