Measuring the vulcan loudness.

Vulcan loudness
I have tried to use simple free app to measure the loudness of my Vulcan.
The app called Decibel 10th.
Here are the results of two shots with standard shroud on with delrin spring guide.
Phone was half meter away from the left side of the gun.
It will be helpful if other people try same app, post results in here with and without modifications
So we can quantify results.
