Acoustic insulation in accordance with EN 12354 is a new module which has been implemented in the Acoustics tab of CYPECAD MEP. This module designs and verifies the acoustic insulation described in the EN 12354 (ISO 15712) codes, by taking into account:
- The acoustic insulation calculations for airborne noise between precincts
- The acoustic insulation calculations for impact noise between precincts
- The acoustic insulation calculations for external airborne noise
- Sound immission, caused by the equipment of the building, between precincts, within each precinct and from outside the building
- Calculations of the reverberation time and equivalent sound absorption area
The Acoustics tab of CYPECAD MEP analyses the acoustic insulation in accordance with EN 12354 and is available when users select a country which does not have a specific acoustic insulation design code or when the ‘Other’ option is selected from the list of countries. The magnitudes used for each type of acoustic calculation are defined in this tab (acoustic insulation for internal airborne noise, acoustic insulation for external airborne noise and impact noise level) and the types of precincts are established for the acoustic calculation. All this information practically defines the standards of any country.
The introduction and definition of the construction elements (imported from the Price Generator for countries for which this option is available, or defined by layers) and the definition of the building precincts, are the same for all countries and for the ‘Other’ option. The acoustic calculation is carried out in the same way as the existing adaptations to the local standards of Spain (CTE DB HR. General option), France (NRA 2000) and Portugal (RRAE):
- Automatically analyses the building, resolving all the possible calculations between acoustic emitter-receptor pairs.
- Provides detailed lists of each calculation that has been carried out and a detailed acoustic study of the complete building.
- Provides graphical information of the indirect transmissions and drawings indicating the worst case acoustic insulation points.
Users must have the corresponding user license permits to be able to use the module for Acoustic insulation in accordance with EN 12354.
