Usually not, that is generally done with a pink noise generator and a
frequency analyzer, the tech sets up for flat, then does a long
walkaround with a mic chopping out feedback issues and tuning to taste.

Pink noise is just normalized white noise, with equal amplitude across
the audio spectrum. (sometimes with weighting for specific purposes)
