SoundPLAN Library
SoundPLAN Source Emission Library with Directivity Example
System, Global and Project Library

The SoundPLAN software organizes data library as System, Global and Project Libraries. 

  • System Library is installed during the software installation and provides a default data set for noise sources, typical noise assessment, traffic pattern, directivity, etc.
  • Project Library is located in the SoundPLAN project folder and is compiled by the user.  As objects are defined for a project the data (e.g., Manufacture, Literature, System Library, Project Library) is entered into the Project Library. When the project is copied the library is copied too.
  • Global Library is compiled by the user. Data from the System or Project Library can be copied into the Global Library.  The Global library allows a user to define a company specific library for common project information (e.g., construction equipment, materials, etc. )
