Materialised’s Hush sheer blind fabrics absorb sound and are flame retardant, wide width and durable. To quantify for commercial acoustic solutions, each is tested and awarded an NRC (Noise Reduction Coefficient) rating.
The range comprises of:
– Soundcheck Blind: NRC rating 0.62
– Frequency Blind: NRC rating 0.57
Woven with a ribbon-shaped Trevira CS yarn, this filament is the key to their sound absorption, managing the flow of sound waves repeatedly passing through and bouncing off a reflective surface. This changes the tone, becoming muffled, and results in the reduction of sound levels.
With the fabric positioned 15 to 20cm from the window or wall, our acoustic engineers found that it could absorb up to five times as much sound as a typical lightweight, non-acoustic fabric.
