Point Source 0dB From Network
=============================

Create 0 dB Source From Roads

Overview
--------

➡️ Creates a SOURCE table from a ROAD table.
The SOURCE table can then be used in the Noise_level_from_source WPS block with the "confExportSourceId" set to true. The Noise_level_from_source output will contain a list of "source-receiver" attenuation matrix independent of the source absolute noise power levels.

Arguments
---------

Mandatory inputs
~~~~~~~~~~~~~~~~
