How It Works

Acoustic Blinds and Curtains leading acoustic fabrics are specially designed to reflect and absorb sound energy to reduce the noise and improve the acoustics of any room.

Our acoustic fabrics are the product of years of research and development - combining natural sound absorbing raw materials with a unique 'fabric construction' to maximise sound absorption.

Acoustic Blinds and Curtains are scientifically tested, and proven effective using global testing standards and in a real world setting.

See below for more details.

Acoustic Test Results

To understand our Acoustic Tests and Test Results - you first need to understand the basic principles of sound and how it travels.

What is sound?

Sound is energy, created by vibrations, transmitted through the air in sound waves. Sound waves have two different characteristics - frequency and decibels.

We hear frequency as 'pitch' - the higher the frequency, the higher the pitch. However frequency actually refers to the wavelength - measured as the number of vibrations per second and is expressed in Hertz.

We hear decibels as 'volume' or 'intensity' - the higher the decibels, the higher the volume.

How does sound travel?

Sound travels by vibrating the air. When sound comes into contact with other objects such as a Blind, Curtain, or Table, the sound can pass through the object, is reflected by the object, or is absorbed by the object. Most objects will do some combination of all three - depending on the frequency and decibel of the sound.

Noise Reduction - Pulse Acoustics

Acoustic Blinds and Curtains commissioned Pulse Acoustics to test the noise reduction and sound absorption qualities of Acoustic Blinds and Curtains in a real world setting.

We conducted the test in a typical two bedroom apartment in Sydney, and the person who conducted the test was Karel Ruber. Karel is a PhD in Mechanical Engineering, specialising in Noise and Vibration.

Step 1 - Use a speaker to create a constant noise
Step 2 - Hang curtains
Step 3 - Measure noise reduction

Acoustic Blinds and Curtains can reduce noise by up to 9dB*

*Every acoustic environment is different. Results may vary

A 5dB noise reduction is clearly noticeable while a 10dB reduction is perceived as reducing the noise by half.

See our Technical Specifications for the test results of all of our acoustic fabrics.

Sound Absorption - Noise Reduction Coefficient (NRC)

Noise Reduction Coefficient is the global testing standard for sound absorption of tiles, panels, fabrics and other building materials.

This test gives the average sound absorption of 4 different frequencies - 250Hz, 500Hz, 1,000Hz and 2,000Hz.

A value of 0 is no sound absorption. A value of 1 is complete sound absorption.

However note that a value of 1 does not mean that all sound in the room is absorbed - only the sound which comes into contact with the acoustic fabric.

Any fabric with an NRC over 0.4 is considered to be 'acoustic'. Our acoustic fabrics are as high as 0.71!

See our Technical Specifications for the test results of all of our acoustic fabrics.
