|Each spectrogram has two versions with identical metadata for each date and location. Those spectrograms labeled with an ''h'' are adjusted to show only the sounds from the recording that are humanly audible, while their corollaries (without an ''h'') show the full spectrum of the recording. Spectral images are taken from calibrated sound level measurements and are displayed in 1/3 octave band frequencies on a logarithmic scale from 0-4000 Hertz.
