Soundproofing
Important information:
The most important parameters for Hyperline flooring systems are described in the overview
below.
Rated degree of longitudinal sound reduction as per DIN 52 210
RL,w,P and Dn,f,w,P acc. to ISO 140-12
|
The measurement is taken horizontally with a high-performance soundinsulating
partition wall placed on the system floor. This determines
an index figure for the floor, which can be used to calculate the sound
insulation index from room to room, incorporating the other flanks and
the partitioning wall in the building. Higher figures are better as they
indicate a higher insulating value.
|
Sound insulation index Rw,P as per DIN 52 210 and ISO 140-3
|
The measurement is taken vertically, i.e. from one story of the building to another, with a standardized structural ceiling.
This allows different systems to be compared. A conversion has to be performed to allow for the structural conditions if the actual structural ceiling differs in its structure. Higher figures are better (due to the higher insulating value).
|
Rated footfall sound level Ln,w,P as per DIN 52 210 and Ln,f,w,P acc. to ISO 140-12
|
The measurement is taken vertically, i.e. from one story of the building to another, with a standardized structural ceiling.
This allows different systems to be compared. A conversion has to be performed to allow for the structural conditions if the actual structural ceiling differs in its structure. Higher figures are better (due to the higher insulating value).

Degree of improvement in footfall sound Δ Lw,P as per DIN 52 210 and ISO 140-8
The measurement is taken vertically, i.e. from one story of the building to another, with a standardized structural
ceiling. This allows different systems to be compared. However, a conversion has to be performed to allow for
the structural conditions in this case, too, if the actual structural ceiling differs in its structure. Higher figures are
better (due to the greater degree of improvement).
The floor covering is not relevant to airborne sound reduction for the hollow floor. The results for footfall sound
reduction depend on the degree to which the floor covering provides an improvement. Ventilation openings,
which might lower the degree of soundproofing, have not been taken into account.
To calculate values for a building, the corrective degrees should be allowed for acc. to VDI 3762. Combinations
of access floors and hollow floors should be assessed in each individual case. The corrective degrees should be
determined by the planner.
