WhisperCloud®
Acoustic Suspended Ceiling
WhisperCloud® is an acoustic hanging panel solution that suspends from ceilings to help control noise.
WhisperCloud is a tracking system used to enable tightly stretching fabric over an acoustic absorber on ceilings.
The panels are designed to provide noise control in large spaces that don’t allow for dropped ceilings or require additional sound treatment. The panels are suspended from the ceiling, providing acoustic absorption and an appealing spatial aesthetic.
Sustainable Acoustic Absorber
The CSR Martini dECO Quiet Board acoustic absorber is manufactured from thermally bonded polyester fibre with up to 80% recycled fibre content from post-consumer PET packaging. It has a Global GreenTag GreenRate™ Level A certification with a Global GreenTag Platinum HealthRATE™ certification and is therefore suitable for Green Star projects.

How It Works
A patented polymer tracking system enables tightly stretching our commercial grade fabric over the acoustic absorbers for wall panel solutions. See NRC ratings in the table below.
With 58 tracking profiles to choose from we are able to cater for any ceiling design situation. The most common tracks are for 12mm, 25mm and 50mm acoustic absorbers. We can work with any specification nominated by an acoustic engineer.
NRC Explained
To quantify our product as a commercial acoustic solution, 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 four different frequencies.
Our Whisper acoustic products are tested at 125hz, 250hz, 500hz, 1,000hz, 2,000hz and 4,000hz. Taking the average number, it is then applied to the NRC scale of 0 to 1. A perfectly sound absorptive material achieves a 1, whereas a 0 indicates no absorption.
Made In Sydney
There are no standard or pre-fabricated panels as we assemble and install onsite with our team of experienced installers.
We print designs onto a flame retardant fabric with a modified weave, allowing air to freely pass through, whilst maintaining printed integrity. Choose designs from our vast print library or work with our team of in-house designers to supply your own.
