Things to say before you start:
You won't get a great acoustic environment by just installing one or two panels in a room (unless it's a very small room), if you have very big problems with poor acoustics.
That would of course help, but it probably wouldn't be enough.
As a general rule, you should cover the equivalent of 25% of the room's floor space with sound-absorbing material in order to achieve good acoustics in the room.
To find out the number of panels, you can use the following formula:
(Floor area x 0.25) / 1.44 = the quantity of acoustic panels needed to achieve good acoustics.
The reason you need to divide with 1.44 at the end is because one Acoupanneau covers 1.44 m² (square meters).
Let's do a quick scenario:
Let's say you have a living room with a floor space of 30 m².
So, in order to calculate the quantity of panels needed in the room to obtain good acoustics, we use the following calculation:
(30 x 0.25) / 1.44 = 5.2
In this case, a total of 5.2 acoustic panels are needed in the living room in order to achieve a good acoustic environment.
All you have to do is round up or down, as we only make whole panels.
It's not that difficult, is it?
