AcouBAT by CYPE

Improvement in the aspect of results

More information has been introduced in the global results list of each space. Now, it is possible to differentiate vertical, horizontal and diagonal orientations for each emitter-receptor couple for indoor airborne noise and impact noise calculations. New icons have also been included for each type of opening, this way, in the version, it is possible to distinguish between windows, skylights, doors, air inlets and roller shutter boxes. Finally, the references of each element have been modified so they correspond with those used in the results list.

List of products used in the project

As of the 2018.a version, AcoubatBIM by CYPE automatically generates a document indicating the products used in the project and their acoustic properties based on the information contained in Acoubat’s library.

Calculation of airborne noise transmitted by roller shutter boxes

A new option has been introduced in the window types of the library, which allows users to indicate if there is a roller shutter box and its acoustic properties based on the products that are available in the Acoubat database. Users must specify the length of the shutter box for each window in the project. This value will be filled in automatically if a geometric BIM model has been imported that contains this information.

Calculation of airborne noise transmitted by air inlets

A new air inlet library has been introduced in the program where the acoustic properties of these elements can be defined. Once the different types have been defined, they can be included in walls and floor slabs of the model as is done with doors and windows.

Comparison of database products

A new tool has been added that allows users to compare the acoustic data of several products of the database. It is possible to select up to 4 different elements whose corresponding acoustic index value graphs of values are displayed simultaneously. This way, users can easily compare the behaviour of products of different manufacturers and/or behaviour.

Links to manufacturer websites

A new option has been introduced in the access panel of the Acoubat database that directs users to the website of the manufacturer of the selected element. This way, a direct connection is established between the products offered by manufacturers and the acoustic analysis software.

Description of the database products

The “Description” tab has been added in the panel of the products contained in the database of acoustic tests of Acoubat. Within this tab, the general definition of the product can be viewed and, for cases for which it is available, a representative image of the element.

Reference of acoustic measurements

The source of the acoustic data has been included in the files corresponding to the products of the Acoubat database. If they have been obtained from laboratory measurements, the reference of the test is also displayed. Furthermore, users can also indicate the origin of the data that has been introduced for the element.

Edit the ProductID in the personalised elements of the database

As of the 2018.a version, AcoubatBIM by CYPE allows for the ProductID of the elements of the database of Acoubat that have been generated by users to be modified. Thanks to this implementation, compatibility issues are avoided when sharing projects containing personalised products with other users.

Project results report

A summary document has been created containing the results of the global acoustic indices obtained for each space, together with the limit values established by users. Similarly, users can configure the elements to be displayed and only show spaces that do not meet all the requirements or values obtained for each separator or connection.

Absorbent layers

The group “Absorbent layers” has been added to the program library. This way, users can include 2D absorption elements in the project model. These, as occurs with furniture, are not taken into account in the sound insulation calculations and only affect the prediction of the reverberation level inside the space in which they are installed.

Since the types of absorbent layers are characterised by their sound absorption coefficient (α), they must be associated with the internal or external side of the partition.
