Hush Light Reduction

Acoustic Light Reduction Fabric

Our range of Acoustic Light Reduction / Opaque Drapery fabrics offer an array of print designs and plain colour options to satisfy the most exacting demands in aesthetics and functionality.

These fabrics offer the look and feel of a soft drape, whilst their technology offers functionality as both light reduction and acoustic control. This delivers an outstanding Noise Reduction Coefficient (NRC) rating between 0.58 and 0.71.

Print Compatible Base Cloths

The following Light Reduction base cloth fabrics are compatible with any of our Materialised print collections:

Readymade Light Reduction Fabrics

Alternatively, we have acoustic fabrics which can be used as stand-alone additions, adding neutral and discreet undertones to your interior space.

  • Cameron available in various colourways.
  • In The Dark available in various colourways.

NRC Rating

To quantify our fabrics as commercial acoustic solutions, each is tested and awarded an NRC (Noise Reduction Coefficient) rating.

The NRC relates to the absorption effectiveness of the material, and is calculated by averaging how absorptive a material is at 4 different frequencies: 250hz, 500hz, 1000hz and 2000hz.Taking this average number, it is then applied it to the NRC scale of 0 to 1. A perfectly sound absorptive material achieves a 1, whereas a 0 indicates no absorption.

With the fabric positioned approximately 15 to 20cm from the window or wall, researchers found that it could absorb up to five times as much sound as a typical lightweight fabric.

At low frequencies, around 200hz, it absorbed no more than about a fifth of the incidental sound energy. However, at frequencies of about 500hz (human ears have a maximum sensitivity between about 3000-4000hz), the fabric absorbed about three quarters of the incidental sound energy.
