Acoustic Fabric Panels To Stop Echo

How to Install Fabric Panels to Stop Echo in a Room

- A very efficient and aesthetic way to reduce noise reverberation or echo in a room is to use custom made stretched fabric panels.
You chose a fabric you like, many are suitable for this application but not all of them.

Why using Fabric?

We use fabric for aesthetic reason and to cover and hide the acoustic absorbers.

Which Fabric Can We chose?

Most fabric are suitable but generally we use a fabric that has a bit of stretch, like cotton, wool or blend cotton-polyester and other type of fibres.
Some fabric have no stretch at all and are harder to install such as some type of silk, fo example.
For an acoustic point of vue it is better to chose a fabric that can breath and allow air to go through.

Where Can We Install the Fabric Panels?

Fabric panels can be installed on any surfaces, walls, ceilings, doors etc...
For acoustic purpose, it is better to install near the corners of the room, that's where usually you'll get most of the noise reverberation.
If you chose for example two walls, you'll get better results if you install your panels on two adjacent walls instead of two oposite walls.

What Type of Acoustic Absorbers Should We Use?

If the room to treat is mainly used for talking, 25mm thick acoustic absorber will be enough.
If you are playing music, music instruments, use subwoofers than you'll need at least 50mm thick acoustic absorbers.
There are different type of acoustic absorbers, rock wool, fibre glass, foam, polyester to name a few.
You'll need to use a high density acoustic absorber, 48-60kg/m3 for example

How many Fabric Panels Do We Need?

A rough estimate is to install between 50-70% of the surface of the floor.
