johan kauppi creates sound absorbing furniture for glimakra of sweden


designer and interior architect johan kauppi has created a set of minimal sound-absorbing furniture for swedish brand glimakra. entitled ‘wakufuru’, the family consists of tables, benches and islands that combine the soft warmth of ash with discreet sound managing technology. quiet in form and quiet in function, the noise dampening collection is imagined by its creators to bring peace and silence to busy restaurants and cosy living rooms alike. the series is set to be unveiled at the stockholm furniture & light fair, running from the 7th  to the 11th of february, 2017.

‘wood as a material, always contributes with a natural warmth in interiors. I wanted to find out if solid wood furniture could also reflect some of the sound atmosphere that is experienced in forests’, says johan kauppi, the designer behind the project. the minimal, rounded shape of the pieces is created using advanced CNC-milling, creating a system-consistent family where all tables and seats are constructed the same way — regardless of height or size. however, every piece of furniture hides an effective sound absorber, built up by several interacting materials that all respond to the volume of the furniture.

for glimakra, the brand for which the collection was designed, ‘wakufuru’ represents the continuation of a long history of working with wood. the open frame construction of the pieces conceal three different layers of sound absorbing materials which interact both with an optimized air gap and the main frame volume. the sound dampening effect works a bit like a reversed loudspeaker, where sound is absorbed instead of being amplified. ‘the diagram shows curves representing measurement data, with and without integrated sound absorption under the furniture. the visual impression of the furniture are the same in both cases — but the acoustic characteristic changes dramatically when sound absorption is integrated,’ says klas hagberg, head of acoustics at WSP acoustics, sweden and acoustic expert on the project.

the pieces are quiet in both form and function



all wakukfuru furniture have identical corners, legs and top structure. to achieve harmonic system capable of being scaled and repeated, a sophisticated CNC-milled corner was developed. frames and leg sections are all CNC-milled from ash wood, with rounded corners making them easy to combine and repeat in various constellations and gatherings. units can be combined to achieve effective sound absorption in larger spaces. ‘the design of wakufuru is very consistent. what differentiates a table from a bench is actually just the length of the legs and the size of the furniture tops’, says the kauppi.
