Akshay Kris New Member N S Akshay Join Date: Nov 2013 Posts: 2 Rep Power: 0	I have an unsteady flow where I have been monitoring pressure fluctuations at a particular point with respect to time. I want to do a sound pressure level spectra analysis of this data which would be SPL vs frequency graph. My question is whether I have to a fft first and then convert pressures into spl or vice versa.. Thankyou in advance !
