I want to calculate the sound pressure level third ooctave using poctave function
I used poctave function to convert pressure data (p) (time,pressure) to 1/3 octave spectrum
[P3rd, cf] = poctave(p,fs,'FrequencyLimits',[df,fs/2],'BandsPerOctave',3);
In order to calculate the SPL-1/3 Octave (sploct)
sploct = 10*log10(P3rd/pref^2);
Is the equation for calculating SPL-1/3 octave is correct or not?
