Defining the project's general data

Under the "Model" tab, in the "General data" group of the main toolbar, different project data can be defined, which will vary according to the chosen code.

Code

CYPESOUND has different codes for carrying out the checks. The calculation can also be performed with customised values:

• Custom
  User-defined parameters, with calculations according to EN 12354 (ISO 15712)
• Spain
  CTE DB HR; Protección frente al ruido (opción general)
• Portugal
  RRAE: DL nº96/2008 Regulamento dos Requisitos Acústicos dos Edifícios
• France
  NRA: Nouvelle Réglementation Acoustique
• Italy
  DRAPDE: DPCM 5/12/1997 Determinazione dei requisiti acoustici passivi degli edifici

Building use and general parameters

When using one of the specific codes, the building use is indicated, where appropriate, and the required general parameters, which are covered by each code, are set.
If a customised standard is selected, the magnitudes of the parameters characterising the acoustic performance of the building and their minimum required values must be defined in the general parameters of the analysis.

In the design options, the quantities to be used to evaluate each type of insulation and the impact noise level are selected.

In the types of space for the acoustic analysis, the limit values for insulation against external airborne noise or noise from adjacent buildings are assigned and, if necessary, the calculations for reverberation time and sound absorption can be activated.

In the interaction between space types, the limit levels for interior airborne sound insulation and impact sound insulation between pairs of enclosures are indicated.
