pointNoise

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 \[dB\]
