What does the weight do?
Many have the opinion that the density of a material is essential for good sound absorption skills in a material. Basically, this is not correct, because weight itself does not absorb!
What promotes the absorption capacity is the structure of the material, and the ability to let airborne sound penetrate the surface without letting too much sound going directly through - and without reflecting too much on the surface you meet.

Acoustic seen, the weight contributes to isolating the sound. A rule of thumb says that a doubling of the weight of a material (i.e. double thickness of a material) will lead to a reduction of 6 dB.
The weight can also have a positive influence on the damping of vibrations and tremors. Examples of heavy materials can be heavy foils or bitumen plates.
B6 Akustik offer numerous products and solutions that can all be fitted into metal parts in machines and cabins etc with the effect that the vibrations (structure sound) are removed - and consequently lead to a great experience of a better comfort.
