The article says the sound is "roughly 30 octaves below the
bottom of a piano". My research and arithmetic show that a frequency
of 1/(120 days) is about 28 octaves below the bottom of a piano,
about 32 octaves below a 440 A, and ~31.34 octaves below middle C.
It's of course possible that my research, my calculations, or my
assumption (the wave takes 120 days, so the frequency should be
1/(120 days)) are wrong.
