Sintered Aluminium Sound Absorption Plate
ALUMINIUM SOUND-ABSORBING PANEL "CALME"
Calme is a sound absorption plates, made of sintered aluminum powder. This porous plate is created with our high sintering technology,
that can control which frequency to absorb by controlling the air layer behind it. It can also be painted and curved without degrading the performance.
■ WHAT IS SOUND ASORPTION?
Usually covering a noise source with board or concrete is called sound insulation.
The sound reflects off the walls and increases, which means the noise level does not get lower.
The sound that leaks from any clearance (e.g. doors, windows, air vents) also increases.
Applying sound absorption makes sound insulation work properly.
It makes the sound decease inside the room, which also allows less sound to leak outside of the room.
Combining sound insulation and sound absorption is essential for effective soundproofing.
SOUND ABSORPTION CHARACTERISTIC
The peak of sound absorption moves towards a lower frequency when widening the air gap or filling
the gap with another porous material, which allows us to maximise the effect depending on the type
■ SOUND ABSORPTION COEFFICIENT AND NOISE LEVEL
➢ -10dB is the same as 10 noise sources reduced to 1.
■ HOW TO INSTALL
In order to obtain effective sound absorption performance, an air gap behind CALME is necessary.
INSTALL WITH GLUE
This method is suitable for low ceilings, walls, and places where the screws/rivets, should not appear on the surface.
INSTALL WITH SCREWS/RIVETS
This method is suitable for high ceilings, swimming pools, gyms and any outside installation.

■ SURFACE APPEARANCE
The surface colour of each Calme is slightly different in colour tone since it is a sintered
porous material, and the difference is still visible even after colouring with standard or a
||Original Silver Gray.
||Any colour is specifiable. (Extra charge is required.)
||Any pattern or image is possible with High quality printing.
