KROSSEN is a set of tiles that form a versatile acoustic absorber panel; their small format, in individual tiles, allows many different patterns to be created with high sound absorption that brings a new dimension of aesthetic and functional possibilities.
They are made with our special ZHFR acoustic foam, with an improved porosity coefficient to obtain the best acoustic performance in the market. Their design also brings an improvement in the reflected sound energy distribution effect (diffusion effect) throughout the room.
Autumn comes to the city, the landscape is tinged with ochre hues, the leaves of the plane trees fall, covering Las Ramblas with a brittle brown carpet... a traditional image that evokes the profiles of this unique tile.
An optimised soundproof treatment for the surfaces furthest from the listener point (back wall and ceiling), mounted according to a random pattern. They soften the reverberation curve and eliminate echo, helping to improve the diffusion of reflected sound energy.
A sound absorption treatment for: control rooms, recording rooms, rehearsal rooms, radio/TV broadcasting studios, home cinema...
The following table gives a guide of the estimated reverberation time depending on the size of the room and the number of pieces installed.
| RT60 at 1kHz [seconds] | Room without treat. * | SKAB005-32 32 uts. pieza | SKAB005-60 60 uts. pieza |
|---|---|---|---|
| 1.2 x 1.2 x 2.2m | 0.76 | 0.40 | 0.28 |
| 1.5 x 1.8 x 2.2m | 1.03 | 0.62 | 0.43 |
| 2.0 x 2.0 x 2.2m | 1.23 | 0.80 | 0.61 |
* The results are obtained by estimation in a standard room with the following finishes: plaster walls and plaster ceiling, parquet floor, one window and a wooden door.
** The 'acceptable' result is suitable for rooms that contain additional furniture (curtains, carpets, bookcases, chairs with fabric upholstery, sofas...)
