sound pressure level (SPL) of a pressure signal (probes))
 

Hello everybody,

I am new to this forum and this is my first thread.:)

About my problem:

I have done a simulation with OpenFOAM. For this I used "probes" in controlDict to write out pressure data over time.
Now I would like to evaluate this data.
I would like to plot the sound pressure level over the frequency (FFT), if possible with matlab or paraview.
I have already done some research, but unfortunately I haven't found anything yet, which is helpful.

Has anyone had experience with this and can please help me?
Many thanks in advance!

Best regards

Tobi

Hi Tobi Wehr,

I am also curious to know how this can be done in OpenFOAM, please don't forget to share your experience once you find it.

Hi K. Rao

so far I haven't been able to make any progress.

I once read about a noiseDict, but so far I do not know how exactly this application works.

This post is way overdue but I found this link to Matlab in case you have access to it:
