ReadSoundPlan
Read SoundPLAN files.
Purpose
ReadSoundPlan is able to read the result of a sound simulation generated by the software SoundPLAN.
Files
The simulation results must be avaible in the following form as txt file to be readable for the reader.
X Y Z W LrT LrN LT,max LN,max
3507180,000 5399925,000 456,16 462,2 33,9 30,3 0,0 0,0

Ports
The first port providing points. The following ports showing the scalar results for different times of day.
Parameters
name |
description |
type |
|---|---|---|
first_step |
first timestep to read |
Int |
last_step |
last timestep to read (-1: last) |
Int |
step_increment |
number of steps to increment |
Int |
first_rank |
rank for first partition of first timestep |
Int |
Filename |
SoundPLAN data file path |

Important to note
The reader operates only on the master node, because it haven’t been parallelized yet.
Example Usage
In the simplest and most cases a visualization of the simulation result can be done like shown in figure 1.
Fig 1: Simple vizualization pipeline.
The Color module maps scalar data onto the points/surface. The DelaunayTriangulator is used here to convert the points into a surface in XY coordinates. As a result the visualization could look like the following picture.
Without the triangulator the picture would look like
