Import sound sources from the BIM model

As well as interpreting the geometry of the project, now it is possible to read and interpret indoor sound sources defined in the BIM model, this way, increasing the degree of integration of AcoubatBIM in the Open BIM workflow. The IFC entities that are recognised by the application, and can be exported to the BIM project by other Open BIM programs of CYPE, include:

Bathtubs and showers
These objects, together with the remaining sanitary equipment, can be introduced using the free BIM modeller, IFC Builder.
Terminal air conditioning duct elements
This consists of grilles and diffusers. To insert these devices, the BIM program for design of air conditioning installations can be used: CYPETHERM HVAC.
VRF, Multi-split and Split 1x1 systems
The same way grilles and diffusers can be introduced in CYPETHERM HVAC.

Sound sources can be imported from the BIM model using this version of CYPESOUND and its corresponding versions to verify the acoustic requirements of national codes (CYPESOUND CTE, CYPESOUND RRAE and CYPESOUND DRAPDE).

Calculation of the sound pressure level generated by building equipment

As of the 2018.g version, AcoubatBIM by CYPE allows users to define indoor noise sources, which are generally due to equipment that is installed in the building. A product from the Acoubat database can be associated to each type of source, and in the case of pipes, a cover. Users must provide details of equipment noise (continuous, intermittent or emergency) with the aim to group all the equipment of the same activity and check the acoustic pressure value against the limit established for each space in the general parameters of the project.

Intermediate results in reports

A drop-down list has been added to each results report containing all the intermediate calculations that have been carried out. This way, users can inspect each path sound can take (partitions, openings, flanks, indirect noise...) without having to leave the results window.

Italian acoustic code D.R.A.P.D.E. (D.P.C.M. 5 December 1997)

As of the 2018.f version, AcoubatBIM by CYPE allows users to import the configuration of the acoustic limits covered in D.P.C.M. 5 December 1997 (Determinazione dei requisiti acustici passive degli edifici). The types of spaces that can be selected, with acoustic requirements, are the following:

Categoria A: edifici adibiti a residenza o assimilabili
Categoria B: edifici adibiti ad uffici e assimilabili
Categoria C: edifici adibiti ad alberghi, pensioni ed attività assimilabili
Categoria D: edifici adibiti ad ospedali, cliniche, case di cura e assimilabili
Categoria E: edifici adibiti ad attività scolastiche a tutti I livelli e assimilabili
Categoria F: edifici adibiti ad attività ricreative o di culto o assimilabili
Categoria G: edifici adibiti ad attività commerciali o assimilabili

French acoustic code NF NRA 2000

As of the 2018.f version, AcoubatBIM by CYPE allows users to configure the acoustic limits of the Nouvelle Réglementation Acoustique (NRA). Specifically, the verification of the following decrees has been implemented:

Arrêté du 30 juin 1999 relatif aux caractéristiques acoustiques des bâtiments d’habitation
Arrêté du 25 avril 2003 relatif à la limitation du bruit dans les hôtels
Arrêté du 25 avril 2003 relatif à la limitation du bruit dans les établissements d’enseignement
Arrêté du 25 avril 2003 relatif à la limitation du bruit dans les établissements de santé
Arrêté du 30 mai 1996 relatif aux modalités de classement des infrastructures de transports terrestres et à l’isolement acoustique des bâtiments d’habitation dans les secteurs affectés par le bruit

Spectrum adaptation term

As has been implemented in CYPESOUND, as of the 2018.f version of AcoubatBIM by CYPE, users can tell the program to add the spectrum adaptation term C or Ctr (depending on the predominant type of noise) to the acoustic insulation index against outdoor airborne noise.

Outdoor airborne noise on façades

As has been implemented in CYPESOUND and CYPESOUND NRA, now, in AcoubatBIM by CYPE, users can force the outdoor airborne noise limit value of a façade of the project. If this option is selected, the program will compare the level of insulation that was obtained for the façade with this new value instead of that indicated in the general parameters of the application.

Furthermore, if the French NRA code is used (also implemented in this version in AcoubatBIM by CYPE), an assistant to determine this limit based on “Larrêté du 30 mai 1996 modifié en juillet 2013”.

Minimum reverberation time

As of the 2018.f version, it is possible to indicate a minimum reverberation time limit in the configuration of the types of spaces.

Reverberation time and equivalent acoustic absorption area depending on volume

As occurs in CYPESOUND, as of the 2018.f version, a new formula has been added to limit the reverberation tine and equivalent acoustic absorption area of a space depending on its volume.

Reverberation time and equivalent acoustic absorption area with and without furniture

Now users can calculate the reverberation time and equivalent absorption area of a space taking into account the furniture included in it, or not taking it into account or with both options.

Reverberation times depending on volume

A new option has been included in the configuration of types of spaces that allows users to indicate different reverberation time limits depending on the volume of the space.

Airborne noise and impact noise insulation between spaces with doors or windows

Now users can indicate a limit value for airborne noise or impact noise insulation between spaces when there are openings between them, different to the value provided for when there are no openings.
