AcouS STICS21®
Software

AcouS STICS21® is designed for construction professionals who need to comply with statutory or programme-specific acoustic requirements in terms of sound insulation against interior airborne noise and impact noise for all types of premises (housing, offices, health or education establishments, etc.) and for many types of construction (concrete, masonry, CLT, wood, etc.).

In addition to our tutorials, training in the use ofAcouS STICS21® is proposed by our development teams.

Software for predicting acoustic insulation against airborne noise and impact noise

AcouS STICS21® is designed for construction professionals who need to comply with statutory or programme-specific acoustic requirements in terms of sound insulation against interior airborne noise and impact noise for all types of premises (housing, offices, health or education establishments, etc.) and for many types of construction (concrete, masonry, CLT, wood, etc.).

Our software is based on the calculation methods of the ISO 12354 series of standards and calculates the acoustic magnitudes DnT,W (C; CTr) and L'nT,W (CI; CI50-2500) in compliance with the ISO 717 and ISO 10140 standards. It can integrate simulations from the AcouS STIFF® and AcouS STING® software suite.

The AcouS STICS21® software is an ergonomic and adapted tool that allows:

  • The optimisation of structure sizes to achieve the desired objectives;
  • The assessment of the parameters influencing the insulation performance between premises;
  • The precise quantification of all the transmission paths involved in acoustic insulation;
  • The integration of complex building systems using simulations of sound reduction indexes and impact noise levels from the AcouS STIFF® and AcouS STING® software suite.
  • The integration of acoustic magnitudes measured in situ or in the laboratory (Kij, Dvij, Dne, DnF, etc.).
  • Access to all results in global values (according to the ISO 717 and ISO 10140 series of standards) and by thirds or octave bands in the form of customisable tables and graphs.
 

It is therefore possible to display simultaneously and in detail the performances of the various structures which compose the premises being analysed to assess their performances and their influences on the overall insulation results sought.

AcouS STICS21® is the latest module to complete the AcouS STIFF® and AcouS STING® software suite. These programmes are used to simulate sound attenuation and impact noise, and have been tested and validated by a considerable number of licensees for several decades in France and in other countries. AcouS STICS21® allows the simulation results of AcouS STIFF® and AcouS STING® to be integrated into the calculation of the insulation between premises of many construction complexes (concrete/heavy/wood/LCT floors, suspended ceilings, brick or block facades, lined or unlined, partitions, wood frame walls, etc.). In AcouS STICS21, users can also integrate their own data from laboratory or in situ measurements (R, Ln, ΔR, ΔL, Kij, Dvij,n, Dne, Dnf, …).

The AcouS STICS21® calculation model

The AcouS STICS21® calculation model is based on the approach of the ISO 12354 series of standards, and of all the latest studies and R&D developments of the GAMBA group.

You will find below answers to some questions you ask and which we hope will give you the information you seek.

Yes, the integration of a false ceiling or technical floor is possible. An adaptation of the laboratory measurement to the in-situ characteristics (dimensions, plenum height, presence of absorbent, etc.) is carried out via a dialog box. There is no particular module for he integration of an ancoustic barrier, but the data (test) of a continuous ceiling with an acoustic barrier can be fully integrated.

The junctions database is the calculation of the KIJ and DVJ according to the junction resulting from the annexes of the 12354 standard, you will find the same values as if you make the calculations with the standard. They will be embellished according to the junctions that we will have characterized on certain assemblies.

The partitions are simulated from AcouS STIFF® (there is a specific partition module being finalized) or you can integrate a test report.

We can start from 0, if you have data you can enter everything in experimental value. It will be necessary to provide certain additional information on acoustic performance (mass, type of facing, etc.)

It is possible to integrate a facade Dnf (wooden frame or curtain wall for example) in horizontal or vertical configuration.

Yes, you can have a partition in a plasterboard partition attached to a concrete facade and with a concrete floor or curtain wall characterized by the DnF and even in absolute terms have a different concrete floor at the emission and at the reception. You can have a different floor covering on emission and reception, etc., each facing is characterized separately.

For the moment no, it is under development

Yes, just drag and drop if you want to compare all the DnTs with all the walls concerned, the same for the L'nT.

The blue is for the ground and the white for the sky in relation to the horizontal and vertical section of the premises to have a representation of the offsets.

Yes, subject to having the data. You can integrate Kij or Dvij,n manufacturer or that you have measured.

All the junctions that you see appearing in the STICS21® database are junctions from the latest version of the standard.

The test report is filled in via a window, then you fill in the values and you integrate them into the DnF experimental values icon. Finally, by double clicking on the experimental value, the window for adapting the laboratory test to the in-situ characteristic opens.

A calculation/measurement comparison battery was carried out to validate the models from in-situ measurements for AcouS STICS21® and from laboratory measurements for AcouS STIFF®/STING®.

The software works like a database, you can create an “.sia” file (AcouS STIFF®/STING®/STICS21® format), once the file is created it is compatible with other files. When you make a new project (new “.sia” file), you can copy-paste your simulations or test report from one “.sia” file to another. There is therefore no need to re-enter the data.

Yes, an EXCEL or OPEN OFFICE import is possible, the import format is provided with the delivery of the software.

The orders of magnitude of the uncertainties are identical to those of standard EN 12354 and depend on the input data.

Yes, they are given in formation. We invite you to consult the 12345 standard to see more details on this. You can access these data in the software by displaying the values of Kij/Dvij,n or Dvij on the graphs/results table.

We made comparisons on several calculation models, we found some slight differences due to the input data (R and Ln in particular), as a general rule, we have the same overall results. We have validated our software whether by measurement, calculation formula or other software.

Yes, we validated by comparisons of calculations/measurements. The orders of magnitude of the uncertainties are identical to those of standard EN 12354 and depend on the input data.

It is not possible to use AcouS STICS21® without AcouS STIFF®/STING®. With the software suite, predefined fixtures (= pre-calibrated simulations allowing extrapolations) and a materials database are provided.

Materials: concrete, asphalt, natural wood, reconstituted wood Solid brick, textile fibers, plant fibers, fiber cements, wood wool, rock wool, glass wool, metals, closed pore foams, open pore foams, polymer plastics, plaster , Rockwool. They are covered during our training.

No it is not configurable. It is standardized at Tr=0.5 seconds as for the majority of the objectives defined by the regulations. If you want, you can export the results and apply a reverb duration fix to it.

To integrate a door into STICS21, you need to enter an insert. To do this :

  • Take "component" to mean "insert".
  • Drag it to "Separative" then "Insert after".
  • By default, in "Insert" there is a CVR Dne that can be deleted if there is no CVR, an air intake Dne that can be deleted if there is no air intake, and a heterogeneous wall.
  • In the latter case, one of the two elements (glazing or multilayer) is replaced by an experimental value.
  • In the latter case, the acoustic test report for the door in question must be entered.
  • Finally, right-click on the experimental value to enter the door surface area.
