"Not all textiles have equal sound absorption qualities"
Sound - The noisy truth
Textiles play a major role in the absorption of sound within everyday spaces such as your home, the office, hotels and conference centres. With the movement toward minimalist spaces and the noises generated within them, the management of sound has become of utmost importance particularly in the design of public spaces.
The popular use of textiles not only adds to the visual appeal of a space, they also provide an excellent medium for absorbing sound helping to increase speech intelligibility and setting the ambience of the interior. Hard surfaces enable sound to bounce and reverberate around spaces, whereas textiles, including drapery and upholstery items not only deliver a design aesthetic but also contributes to the absorption of sound. The reduction of sound reverberation creates more holistic spaces where conversations can be heard and background noise is minimised.
However not all textiles have equal sound absorption qualities – the level of sound absorption is dependent upon the textiles weight, composition, and/or construction. Generally, due to mass, drapery provides the main textile source of sound absorption and we find:
- The more drapery folds, the more sound absorption
- Hanging a curtain a small distance off the wall increases sound absorption
- Softening opposing walls reduces sound waves from travelling wall to wall
Sound Absorption Measurement
Our FR-One textiles are laboratory tested for sound absorption in accordance with EN ISO 354. They are provided with an official Noise Reduction Coefficient (NRC) of between 0 and 1.
At the 0 end of the spectrum all noise is reverberated and it is considered a hard surface not absorbing any sound. At the other end of the spectrum, 1, the textile absorbs all sound.
These results are commonly converted to a sound absorption class as per ISO 11654, from A to E, with A being the highest absorption class rating. However a class of A, B, or C are highly absorbing textiles that will effectively assist in reducing sound reverberation in a space.
