Input and analyses
2.1
General data
2.1.1
General parameters
The job entry begins by inputting the
´General data´ in the ´Model´ tab.
In this window users can access the
parameters allowing the analysis options,
types of spaces used in the project as well
as the acoustic interactions between these
space types to be filled in.
A configuration can be imported and saved
using the buttons located to the right.
2.1.2
General parameters
Design options
In the ´Design options´ window the values used in
the project
must be entered, as well as the group of
façades used in the analyses.
In the ´Types of spaces for the
acoustic analysis´ window, users must
enter the spaces present in the
project.
Design options
AcouBAT by CYPE / 5
The buttons located in the top bar allows the type of spaces to be entered, modified,
deleted or exported.
Types of spaces for the acoustic analysis
By double clicking on a space its acoustic characteristics for analysis can be accessed. The
requirements must be entered for each type of space.
The ´Acts as a source space regardless of the use unit assignments´ box allows a space to
be considered as an emitter regardless of the use unit in which it is present.
AcouBAT by CYPE / 6
In the ´Interactions between space types´ window
users must enter the insulation values for the
insulation against airborne noise and impact
sound insulation between the receiver and emitter
spaces in the project.
Interaction between types of spaces
2.1.3
Acoubat Library
In the
´Acoubat Library´ window users can find the Acoubat
database managed by the Scientific and Technical Centre for
Building in France, the CSTB.
Each product is classified according to different categories
depending on its use in the building.
A product search engine and a comparison tool are available to facilitate the final decision.
In addition to the products from Acoubat, it is possible to add new elements by manually
entering their acoustic characteristics.

Library
2.2.1
Organisation
The library contains the reference for each element of a
project. The features of the spaces, the walls, roofs,
floors, openings, air inlets, connections, absorbent
layers and furniture of the building must be entered
here.
All library elements can be exported and then imported
into a new analysis.

2.2.2
Spaces
The spaces appear first in the library tree structure.
In this menu, users can choose for each space whether they are ´Defined or Excluded´ in
the a

2.2.3
Construction elements
The construction elements are made up of at least
one base element that must be filled in. Users can
also add interior and exterior linings for the walls
and partitions and the upper and lower linings for
the roofs and floors.
For each construction element, users have direct
access to its composition as well as to the acoustic
characteristics of the elements of which it is
composed.
The materials are directly selected from the Acoubat
database by CSTB.
Construction elements
In the database included in AcouBAT by CYPE, users have access to the program’s product
files with all the necessary acoustic characteristics by type or by manufacturer. Advanced
search and comparison tools are available in order to choose the product that best
matches user needs.

cture, air inlets can be created and
introduced into the project.
As for the other elements, a product catalogue is available in the
program with the view of the acoustic characteristics.

Absorbent layers and furniture
The ´Absorbent layers´ and ´Furniture´ menus allow users to add the elements present in
the project and then introduce them into the spaces.
As for the other elements, a product catalogue is available in the program with the view of
the acoustic characteristics.

Use units
2.3.1
Organisation
The ´Use units´ menu contains the use units and
spaces of the project whose type, construction
elements, air inlets, absorbent layers and furniture
have been previously defined in the library.
Organisation of the use units
AcouBAT by CYPE / 11
In AcouBAT by CYPE, users can arrange the spaces into use units based on the checks they
wish to carry out.
In the ´Spaces without a defined use unit´ section, users can put the spaces that they do
not wish to classify.
Users can create new use units by clicking on the ´New use unit´ button.
When a use unit is created, a new space can be associated with it using the ´New space´
button.
Users can also use the edit buttons in the use units menu to ´Delete´, ´Duplicate´,
´Displace´ and ´Copy/Paste´ the use units and spaces in their building. To access these
buttons, go to a use unit or a space in the ´Use units´ tree structure. Click on the ´Multiple
space editing´ button to perform multiple operations.
2.3.2
Use unit
Users must group together in a use unit the spaces
belonging to the same area for acoustic analysis (all
the rooms of an apartment in a multi-family
dwelling).
Use unit
2.3.3
Space
At the space level users can find the associated type,
the area of the
space as well as the volume between
the floor and the suspended ceiling.

In each space users can view and manage the walls, roofs and floors of which the space is
made, as well as the air inlets, absorbent layers, connections and the associated furniture.
2.4
BIM model
In the case of an analysis created
from importing an IFC file, the
elements being edited can be
viewed on the BIM model in the
view window.
When selecting an element in the
project’s tree structure it is
highlighted.
This topic is covered in more detail
in the third part of this manual.

By clicking on a space, the analysis details for each element of the space are displayed.
Information on direct and lateral transmissions can also be found.
By clicking on an element, its
location is displayed in the 3D view.
The report icon in the ´Results´
column allows users to view a detailed
report of the analysis.
In these reports, users can access the
calculated magnitudes (indoor and
outdoor airborne sound insulation
and impact sound insulation level).

BIM interoperability
Definition: The IFC model is a digital model of the building in IFC format containing the
base construction elements (walls, floor slabs, roofs, doors and windows, spaces and space
edges), as well as the relationships between these elements, which we call ´IFC Building
Model´.
AcouBAT by CYPE / 18
4.1
Importing a digital model
4.1.1
Creating a project
When creating a new project, users are
asked whether or not they wish to
connect it to a BIM project. It is
recommended to connect it in order to
be able carry out updates when there are
modifications to the IFC model.
If users do not wish to connect it to a BIM
project, they can import an IFC model
without
the possibility of updating it.
Creating a project
Note: in order to connect to a BIM project, users must first create an account on
BIMserver.center and then connect it in AcoutBAT by CYPE.
4.1.2
Import options
When connecting to a BIM project, select the project directly on BIMserver. Alternatively,
without connecting to a BIM project, it can be imported from a local or network directory.
AcouBAT by CYPE / 19
Import options
Then choose whether to assign types to the elements of the model. This option allows
elements to be imported from an existing library.
By importing the IFC files exported from IFC Builder, users can import the edges of the
buildings for the definition of acoustic transmissions.
4.2
Introduction of the model
Once the BIM model has been
imported,
its
construction
elements will be classified by
type in the library. Users must
then define them to remove
the error message they display.
Folders whose elements still need to be
defined are marked with exclamati
on
marks. If they contain no elements they
will be marked with small white
squares.
Introduction of the model
Red crosses that appear in the ´Used´ column indicate that an element is not present or
no longer present in the BIM model.
AcouBAT by CYPE / 20
4.3
Updating the BIM model
Updating the BIM model
If when importing the ´Connect with a BIM model´ option was chosen, each update of the
IFC building model will be marked with a warning triangle on the´Update´ button.
Click on this button to update the geometrical modifications made to the IFC model.
Users can then choose the elements to be modified or deleted. Do not import the edges if
the definition of the thermal bridges needs to be kept as it is.
