silencing through design

At an early stage humans developed five senses; taste, touch, sound, smell, and sight. Out of these the latter three are of extra importance for our survival. We have chosen to focus on sound. When our ability to hear first evolved it was primarily used to identify danger, locate its origin and figure out the best route of escape. Nowadays we are faced with a completely different challenge. We live in an information society where the ability to distinguish voices and sounds is essential to be able to sort and make use of information. In order to not be distracted by unwanted sounds we have...

POST CORY GROSSER Inspired by a simple envelope, with its clean lines, creates symmetry in a playful way. By mounting Post in various angles it generates tension, beautiful shadows and patterns.

For us, good design is like a great meal with friends: the ingredients have to be right, the dish sould be individually prepared, the spices fine tuned. Someone enthusiastically tells an interesting story. We laugh a lot, the wine is good, we keep the memory of a wonderful evening for a long time. At the beginning of the design development is a brainstorming: simple • easy • like a picture • uncomplicated • variable • concise • formally reduced • self-explanatory • independently detailed • innovative. At the end there is Clamp WALL HEIGHT WIDTH DEPTH TOTAL D. ^cophor^" INSIDE'

Hertz is a series of sound absorbers with excellent sound absorption properties that is available in a total of 15 different formats. Its stylish, understated design means it is simple to apply to different types of environments.

JOHAN LINDSTÉN Like its name, the inspiration comes from the iconic, traditional Chesterfield sofa and its timeless design that has become synonymous with deep quilting. The height differences of the sinusoidal curves give the sound absorbers their characteristic design at the same time as reinforcing their acoustic and absorbent properties. CHESTERFIELD HAS HIGH ABSORBENCY PROPERTIES THANKS TO ITS INNOVATIVE CONSTRUCTION. IT MIXES A VARIETY OF ABSORBENCY DENSITIES: HIGH DENSITY CLOSEST TO THE WALLS AND LOWER DENSITY FURTHER AWAY FROM THE WALLS. IT CREATES A GOOD BALANCE IN THE IMPORTANT...

JOHAN LINDSTÉN Loop is made up of four identical arcs/radii which together create a geometric basis for expansion. You can adapt the look of the exterior depending on how Loop is positioned and with an offset you can create a playful, billowing design along the wall. HEIGHT 60,5 CM WIDTH 60,5 CM DEPTH 6 CM

The aim and intention of Romb is to create an intricate, graphic silhouette with a blend of rhombuses, triangles and hexagons which, when combined as a whole, create a visually attractive pattern. Various parallel characters can be seen in the structure, depending on how it is viewed. HEIGHT 60,5 CM WIDTH 60,5 CM DEPTH 6 CM JOHAN LINDSTÉN

Illusion, with its beautifully balanced design, is an efficient sound absorber thanks to the way it is constructed. The pleats create a larger exposed surface, while the cavity behind provides the absorber with the airspace it needs to work efficiently in the medium frequency range.

BOTTCHER & KAYSER BOTTCHER & KAYSER Versatile, flexible and playfully useful. The new acoustic panel system Mag designed by the German design duo Bottcher-Kayser has a modern design idea with great flexibility and can be used with great variety. In addition to its sound absorption, Mag can be used as a space separator if you want to create a more private area. Thanks to the magnetic edges of the panels, you can quickly and easily vary the composition of the panels, disassemble them or connect them without the need for tools. Through the wide range of fabrics, it is easy to create new...

Sound consists of energy. The difference between sound and, for instance, light is that sound needs particles to move through. Sound needs a medium, usually air, to be able to transport itself from point A to point B. Sound also needs something to initiate vibrations, such as a hammer hitting a nail or a guitar string being played. Furthermore, the ear and its ability to distinguish sounds is an essential component in the acoustic environment. The energies that constitute sounds vary depending on the frequency of the sound waves. A bass will propagate sound waves with more energy and low...

A huge problem are classrooms, where there in normal cases are only one source of sound in a specific part of the room (the teacher speaking). Closest are the students on the first row who receive the direct sound. Those who are seated further back receive, besides the direct sound, reflections that bounce off the roof and walls. In this untreated room we get an unwanted flow of sound, such as undecipherable words. The results is that the room feels disturbed and chaotic. Solution: This example describes the function visually. When the sound wave from the teacher hits the panel the energy...
