Thomas Imhof, Acoustic Designer for our reference Brugg Cables, Brugg/Switzerland

How do you design the best possible acoustics for a room?

First you have to decide what a room is going to be used for. There are different acoustic requirements for a classroom than for a restaurant, and you don’t want a church to sound the same as a multipurpose room. The size, shape and use of a room determine the level of sound absorption that is required.

And how do you ensure a perfect result?

We have intensive discussions about the ideal properties for the surfaces of the floor, walls and ceilings, and we keep making calculations until the result is satisfactory to the owner of the building, the architects and the acoustic experts. The results in Brugg were so impressive that we did not even need to carry out the technical measurement of the reverberation time.

What do you particularly like about fabrics from Création Baumann?

Création Baumann has every new fabric tested in an echo chamber and makes the results available to the construction company. Acousticians need the data about frequency-dependent sound absorption and flow resistance in order to work out the acoustics for the room. Fabrics with no acoustic test information are very risky for the planner.
