Point-based noise🔗
Example input:
noiseModel pointNoise;
pointNoiseCoeffs
{
// Common entries (see above)
// Input files list
files (<file-path-1> <file-path-2> <file-path-N>);
}
The point noise model can only be run in serial mode.
Pressure data is read in CSV data format
- point data generation: probes
Output:
- Text files
-
Prms_f.dat
: frequency vs RMS pressure [Pa] -
PSD_dB_Hz_f.dat
: frequency vs Power Spectral Density [dB/Hz] -
PSD_f.dat
: frequency vs Power Spectral Density [Pa\(^2\)/Hz] -
SPL_dB_f.dat
: frequency vs Sound Pressure Level [dB] -
SPL13_dB_fm.dat
: centre frequency vs 1/3 octave Sound Pressure Level [dB]
-
