Rockfon: Optimal sound absorption in colours and shape

Located in a small city on the Danish peninsular of Jutland, Naturkraft invites visitors to learn about the power of nature through various attractions – and having the right colours and great acoustic solutions are an important part of the customer experience.

One of the park’s main attractions includes three spheres, where short films projected on the ceiling showcase various scenes of natural phenomena. To create a quality experience that Jens Erik Thøgersen (head architect) wanted to offer guests, the three domes had to have high performing building materials, including best in class acoustics.

Jens Erik Thøgersen explains that 'The round shape makes the sound reverberate back from all directions. Therefore, we had to make sure that we both regulated the sound outside the sphere and that we had great sound absorption inside the sphere as well. At the same time, we also wanted to project a film onto the ceiling of the dome, which meant that we had to have the right colours inside the dome to create the right atmosphere.'

'In order to successfully achieve this, we chose to use acoustic ceiling tiles from Rockfon because it met all our requirements. After testing several of Rockfon Color-all® ceiling tile range we chose two tones of grey, Concrete and Anthracite, which gave a nice dark contrast and at the same time perfectly showed what we wanted to project on the ceiling', said Thøgersen.

In addition to complying with the requirements for acoustics and projecting images, it was also important that the ceiling tiles could be adapted to the circular shape of the spheres. The acoustic ceiling solution Rockfon Color-all ® not only was able to provide optimal sound absorption, but they were available in the exact colour shade that Thøgersen envisioned for the space. Additionally, the ceiling tiles were able to be customized in special dimensions, which get smaller and smaller as they climb the interior of the sphere.
