The Acoustic Works are composed of several layers of textile, each with a specific density and texture, designed in order for sound waves spread and get lost in the fabric, rather than bounce back into the room, like walls, ceiling and glass does. When sound waves don't bounce back, it avoids echoing (reverberation) of sound.
The material we use in our acoustic works absorbs about 95% of the sound waves (Aw 0,95) that hit the work, which is one of the best, if not the best sound absorbing quality on the market.
The Acoustic Works have the biggest impact near the receiver of the sound, at ear height. For instance, at your desk or your dining table near the receiver(s). This way, a single Acoustic Work can lead to a significant improvement for the receiver, even in a big space. The bigger the surface, the greater the effect will be. To make a bigger impact, you can place one or more Acoustic Works on other walls nearby, preferably opposite each other, so that sound waves cannot bounce back and forth.
Sorry to say this, but 'it depends'. It depends on the layout of your space, the height of your ceiling and it depend heavily on the soft materials already present in your space, because these already absorb some sound. If you don't have any soft furnishings, so no carpet, no curtains, sofa etc, then you will have significant improvements to make. For offices without any soft materials there is a rule of thumb to apply acoustic materials totaling about 1/3rd of your floor surface. So in that case a room of 10m2 would need about 3.3m2 of acoustic materials. However, most likely you already have soft materials that absorb some sound in the space. Then you can use much less surface to improve acoustics. We advise to hang the Acoustic Works where the echoing is strongest. The best place is to hang it near the receiver of the sound, at ear height. To make a bigger impact, you can place one or more Acoustic Works on other walls nearby, preferably opposite each other, so that sound waves cannot bounce back and forth.
