Designer eyewear manufacturer Silhouette International has high standards for the quality of workspaces. After moving into the new 2-hall injection moulding production facility, however, seasoned workers started to struggle with headaches, dizziness, and losing their sense of orientation.

In the acoustical analysis we identified the sound quality and sound-scattering properties – rather than the sound pressure level – as sources of these problems. As a resonance space, the hall "moulded" the sound of the machines into a dense, monotonous stream of noise, making it difficult to identify functional areas, monitor machine performance by ear, and talk with each other.

To create a good acoustic situation, we restructured the space with custom-designed architectural elements made of softwood, natural plaster and cement. Tuning the space has resulted in a well-balanced frequency spectrum, including a lower sound pressure at a fourth of the original level, and has given the space acoustic transparency and a positve, friendly atmosphere.

Tuning the space instead of muffling its sound – an effect the company's CEO had learned to dislike from conventionally treated spaces –, has made it possible to enhance the generous character of the hall and make it a safe working environment.

Even Silhouette testimonial Patrick Dempsey is smiling again.

Some machine sounds (such as the rattling of a chopping machine), that used to be able to dominate the entire space, stay now within the immediate environment of the source. Both events and spatial areas appear now well defined and are easy to distinguish. The acoustic representation of distances has improved - what is near sounds now close, what is further away sounds more distant.

Between the machines.

Talking with someone in the hall today, even when all the machines are running, one can hardly imagine how tiresome the situation was before the refurbishment, when you had to come awkwardly close and still had to yell at each other to make yourself heard.

Two new types of technical solutions we have developed to efficiently calm machines emitting low frequency noise are now being used in several departments of the company, and in this hall as well.

"A production floor like a Stradivarius?! Now I get to experience every day how extraordinarily well Inès and Fabian Neuhaus have translated their theories into practice, and what I had been looking for until then: acoustic design that feels right, that is aesthetically convincing, and enhances the architecture as a whole."  > complete statement

"Finally, on behalf of my department, I would like to thank our management as well as Mr and Mrs Neuhaus for improving our working conditions. I wish for the Neuhaus company to have many future clients who all find their work as positive and convincing as we do."
