Supplied materials: Project for sound absorption and performance in a sports hall.

1. Ecologically clean wooden boards – “CELENIT”

2. Stone wool with a veil – “IZOCAM”

Thanks to the properties of these materials and the good acoustic design, we have mastered the reverberation in the sports hall and reduced the noise to a minimum. We improved the acoustics and introduced creative solutions for sound absorption on ceilings and walls.
