Many of you may be wondering about those perforated wood panels that often cover walls and ceilings in conference rooms, auditoriums, and even bars and restaurants. They are acoustic panels, made of MDF with different finishes, which have a high degree of sound absorption. They are used to correct acoustic defects.
Sometimes, depending on the dimensions of a room¡ and, the materials and elements present, there may be some very annoying acoustic alterations, such as reverberation.
Sometimes, depending on the dimensions of a room¡ and, the materials and elements present, there may be some very annoying acoustic alterations, such as reverberation. Reverberation is a mismatch in the time that a sound remains in the environment compared to ideal for correctly hearing and understanding a message. Technically, reverberation time is defined as the time it takes for a sound to fall by 60 dB after the source of the sound emission stops.
Perforated wood panels work as follows: When incident sound waves reach a sound-absorbent material such as that of Spigogroup panels, some of the energy is reflected, some is absorbed by the material and the rest is transmitted. Depending on the density and type of grooving, the panels have a different sound absorption capacity. All you have to do is choose the panel with the necessary level of absorption to correct the reverberation disturbances.
Finally, in order for this wood interior cladding to match the design of the room, you have to choose the finish. You can opt for natural wood, melamine, through-dyed MDF, lacquer or high-density veneering (HPL).
