Hello every one.
I've spent alot of time searching and looking for the noiseDict because when I tried to use the noise utility the program asked for this dictionary.
Based on the noise.c I built this noiseDict and I don't know if it the correct one

/*--------------------------------*- C++ -*----------------------------------*\

    location    "system";
    object      noiseDict;
}

        separator       " ";
    }

But when I tried to execute the noise command in my terminal in a case folder of a simulation of flow around an obstacle (S-A DDES with a pressure data recorded py a probe) the following error message came out.

So any idea about that definition above ????

Hi,

The reason for the error is missing semicolon after "pressureData".

Hello, I try to CAA simulation flow around the cylinder. I finish my simulation and use the probe for measure velocity and pressure behind the cylinder. Now I try by my noiseDict compute SPL. How format do you set up in probeDict?

noise documentation is incorrect.
