Hi, i make SPL (dBZ) measuremet with mi UMIK-1 and Rew in RTA in third octave, then export the measurement as a text, but the text file give me a lot a frecuency beawteen the third ctave band, i want to know if i have to do the energetic sum of SPL in each frecuency Third octave band, or just have to select the SPL in the frecuency more similar to each third octave frecuency?


I attach a PDF with pictures and the explanation of what I want to do. I hope yo understand and can help me

If you use the RTA in 1/3 octave mode and have it set to use bars on the plot then after you save the measurement from the RTA you can export as text and just pick the figures that are close to the RTA centre frequencies and use those, you don't need to do any further processing on them.
