These tiles are perfect for treating high/mid frequency sounds and covering walls. A more modern design gives a great unique look to your studio.
CNC Profile Cut Open Cell Melamine Treated Grey Acoustic Foam, 25kg / m3 Density Foam which has a controlled permeability and open cell structure that gives optimum acoustic performance for a foam of this density. Hardness 125 to 155 Newton’s.
All foam products supplied upon leaving our factory conform to the requirements of Schedule 1, part 1, of the Furniture and Furnishings (Fire) (Safety) Regulations, S.I. 1324 of 1988 (amended 1989), (Amd 1993), and are also suitable for applications requiring FMVSS302. The fatigue class is based on BS3379.
Please note all polyurethane foam will react to UV light and can fade and yellow over a long time. Fading in colour will in no way affect the foams sound absorption performance.
Noise Reduction Coefficients
NRC ratings have classes, Class A has the highest sound absorption and E the lowest and it should also show the specified overall dept of system (o.d.s), this must always be stated for a given sound absorption class.
The ASTM standard C 423 specifies two different single values of sound absorption; the NRC (Noise Reduction Coefficient) and the SAA (Sound Absorption Average). Both values are calculated as an average over the frequency ranges (250-2000 Hz and 200-2500 Hz respectively).
NRC gives an overall indication to the materials absorption properties. In the case of acoustically treating a room you may need to be more selective than this. The document where the NRC data is derived from will also show the materials absorption at many different frequency responses. This is where you can see what the material will do at the frequencies you need to tackle.
In the case of acoustically treating your room you may not always want a highly absorbing foam tile. For example if you want to take some reverberation out of the room, yet still keep some liveliness, a thin foam tile with a class D rating might be just what is needed to take the highs out. A general rule is the thicker the tile the better it will deal with mid’s and lows.
