Representative spectrograms showing the same song in an airborne channel (A and B) and a substrate-borne vibrational channel (C and D) for a typical male (A and C) and a purring male (B and D). Time is shown on the x-axis (seconds), and the colors (purple < red < orange < yellow) represent the power present at the various frequencies shown on the y-axis.
