Reducing reverberations to create holistic interiors
A Guide to Acoustic Textiles
Sound bounces off hard surfaces and reverberates, reducing privacy, ambience, and speech intelligibility within interior spaces.
Textiles and soft furnishings work to absorb these reverberations; however, not all textiles perform equally as absorption depends on the weight, composition, and/or construction.
Due to mass, drapery textiles are the best source of sound absorption. Performance can be enhanced by:
· Installing folded/layered fabric (e.g. pleated curtains or linings)
· Hanging curtains a small distance off the wall
· Softening opposing walls to reduce sound waves travelling wall to wall
MEASURING ACOUSTIC PROPERTIES
MEASURING ACOUSTIC PROPERTIES
FR-One textiles are tested for sound absorption in accordance with EN ISO 354 and provided with an official Noise Reduction Coefficient (NRC) between 0 and 1. 0 denotes a hard surface where all noise is reverberated, while 1 denotes a textile which absorbs all sound.
These results are commonly converted to a sound absorption class as per ISO 11654, from A to E. Although A-rated textiles achieve the highest absorption rating, those rated B or C will also effectively reduce sound reverberation.
