3.7. Acoustic design
3.7.1. Advantageous layout
An important factor for the assurance of acoustic insulation
is the design and implementation of an acoustically advanta-
geous layout.
The following measures have proven to be of significant
influence to the level of noise generated from the soil system
inside the building:
Noise-sensitive areas should be kept away, as far as
possible, from sources of noise
Non-sensitive areas should, wherever possible, be used
as “buffer zones”
Noise-sensitive areas should not be positioned in the
direct vicinity of bathrooms, toilets or stairwells
Potential sources of noise should be “bundled together”
in the same area
The comparison between the two examples of layout shown
above demonstrates how the acoustically advantageous lay-
out in the second example contributes to a clear reduction
in the acoustic pressure of the systems in the room which
demands acoustic insulation.
However, even using highly efficient low-noise waste systems
like Wavin AS+, one always has to seek for the best possible
acoustic decoupling. This goes for the whole drainage system
and its points of contact with the building (collars, crossings
through walls and floors, plaster residues between the pipe
and the building, etc…).
In designing piping, moreover, we need to avoid positioning
waste pipes in the partition walls between apartments. Special
noise-reduction measures also need to be adopted when
fixing drain pipes to the partition walls between apartments.
Protect the pipes from the propagation of intrinsic noise.

The comparison of the floor plans above demonstrates how
good acoustic design in the lower building example can
significantly reduce the noise levels to which areas requiring
noise protection are exposed.
