Articles about sound environment
An important factor for well-being is a pleasant acoustic environment. Here we share our collective knowledge and experience together with experts from various industries and fields.
Construction and testing
In the same way that sun protection allows different proportions of light to pass through, reflect, and absorb, a curtain does the same for sound. The more compact it is, the more sound is reflected. The more porous it is, the more sound is allowed to pass through. So the challenge is to find solutions where friction occurs between the sound and the surface it hits. The more friction created, the more sound is absorbed. The sound waves are converted to heat in the curtain and therefore no longer exist. Many believe that thicker fabric automatically absorbs sound better. But that's not the whole truth.
This is how our curtains are tested
Our acoustic curtains are tested according to the industry standard ISO 354: 2003. This way, we find out what sound absorption coefficients they have and what classes they belong to. The tests are conducted in the sound lab at Müller-BBM in Munich. Each curtain is hung in a reverberation room and tested several times both flat and pleated, both 15 cm from the wall and also 10 cm from the wall, which is not actually required for sound classification. On each product page, there is a detailed test report if you want to find out how a curtain performs in detail.
