Silent is the concept of the Acoustics Factory where nature and the workplace meet. Beautiful natural and acoustic objects which together give a great effect to the office and working. Who doesn’t want to work in the woods? Silent rocks are a fun way to give an interior a bit more liveliness. The different sizes combined give a playful look and provide better acoustics in the room. The different sizes and colors can be combined as desired.

 

Natural silent solutions for the office

 

Natural fibers

Our acoustic blankets are made from natural fibers. These are 100% eco-friendly. Should an object be replaced, we will come pick it up for you, and the blankets are recycled into compost.. 

Because natural fibers have an environmentally friendly production process, they offer a good alternative to wool or acoustic melamine blankets which have a production proces far more harmful to our planet.  

We use 100% eco-friendly materials

 

The Silent-rock is produced with formaldehyde-poor wood.

Specifications

In order to improve audibility and a general sense of comfort our products absorb sound waves (reverberations), particularly in the frequency range of speech, which is between 100 Hz and 3000 Hz (see graph). In the graph you see the absorption coefficient of carpet and our product. Carpets and curtains give the room a warmer tone because they only absorb high frequencies. However, a warmer timbre gives a rounder sound, but does not help in addressing fatigue caused by excessive reverberations.

Our products are particularly aimed at the speech range. The acoustic hedges have the highest absorption coeffiecient (AW) of 1.2.
