In recent years, we have been doing more and more acoustic adaptations to churches. This helps reduce excessively long reverberation times to appropriate values, making speech, singing and music clearly audible. Adaptation also helps to reduce unwanted noise generated by users of the building (such as footsteps or conversations).

In Ciechanow, after acoustic measurements and analysis, it turned out that it was enough to perform adaptation in only some fields on the ceiling to achieve the expected values. The color of the Sonaspray® K-13 plaster was chosen to match the beige color scheme of the walls already in place.
