Sound Signals - How to find max value of periodogram(y) ?

Context: reading .wav files of child vocalizations and trying to map out formants from there.
I have plotted the sound signal and used periodogram(y) to get the output energy spectrum graph.
We're testing ranges for formants, so I have predefined maxes.
  1. What is the y-label for source signal? --> dB?
  2. What is the y-label for the power spectral density- periodogram(y) plot? is that just magnitude || intensity?
  3. audioread only reads y, how do I loop through and find the x values that go with
Code:
%% find local maxima in the following ranges
%F1 range
for x1=200:800; %frequency range considered
F1=max(y);
end
%F2 range
for x2=800:1800; %frequency range considered
F2=max(y);
end
%F3 range
for x3=1800:3500; %frequency range considered
F3=max(y);
end
