Mila-wall Acoustic

Mila-wall Acoustic

Better acoustics. Better appearance.

The new sound-absorbing panels from the Mila-wall series combine aesthetic wall design and demonstrated acoustic improvement. Given the slim depth of the wall, it‘s amazing how effectively Mila-wall Acoustic reduces reverberation.

When several groups tour through an exhibition, annoying background noises affect the visitors. Fabric covered walls have been used, and while effective, the aesthetic result was troubling to visitors and employees. We’re pleased that there is now the new Mila-wall acoustic panel. It’s as appealing as Mila-wall, but noticeably reduces the reverberation in the room.

The frame of this new acoustic wall is based on the materials and construction of the Mila-wall-100 series, but optimized for maximum sound absorption. From the outside, a structure of micro-fine holes is the only variant. How the sound is captured inside the wall is a design secret.

Impressive sound absorption

Mila-wall acoustic was developed in collaboration with the renowned Fraunhofer IBP. The picture shows a wall module during tests at the Institute, where outstanding sound dampening values were measured.

Simulation of the Fraunhofer IBP

The exhibition spaces of Hilm-Boeckmann-retrospective of the LWL Museum of Archaeology in Herne were the basis for an impressive demonstration of the reverberation reduction with acoustic walls from the series Mila-wall Acoustic. In a simulation of the Fraunhofer IBP, normal Mila-wall modules were compared with Mila-wall Acoustic. The noise reduction is clearly identified. Results of the comparison can be seen in the diagrams and sound files below.
