When designing the Wedel Chocolate Factory in Warsaw, the issue of noise in the main spaces with displays was taken into account. The gain associated with increased speech intelligibility in such situations is felt by every visitor, which always increases the comfort of being in this type of facility. We encourage, by the way, to use this solution more often in closed spaces with a lot of people traffic.

For this implementation, we used Sonaspray® K-13 acoustic plaster on the ceiling in three different colors. This type of "lambskin" creates a pleasant combination with the interior concept used in the Factory, even in areas with a more austere appearance.
