What is acoustics?
Acoustics is about the comfort in a room focusing on sound. It is about reducing the long reverberation time (this is the time it takes for sound to drop to 60 dB) in a room to make the acoustics optimal. By reducing the length of the reverberation time, you create a peaceful room.
If the acoustics in a room are good, there are no reflections of sound, because the reflections are absorbed by these acoustic materials. This is because materials with an open structure have the property of absorbing sound, so that the sound disappears into the material.
Example:
The following pictures clearly show the effect of acoustic materials in your room. In the first picture, the sound continues to bounce around in the room, causing a long reverberation time. In the second image, a ceiling element and a photo panel have been added to the room and the sound is directly absorbed by the acoustic materials, reducing the reverberation time.
