Probably, concede scientists– the pounding of waves on the continents make it possible that the Earth not only hums at a resonance below the human range of hearing, but is part of a larger interstellar symphony that passes several octaves below our sensory perception every day.

This poses the very valid question, how did we figure out that the planet makes noise?

The answer, of course, is to listen very, very carefully– the Black Forest Listening Station in Germany, described as “exceptionally quiet”, uses several ultra-sensitive seismometers to detect the vibrations, which carry near 10 millihertz. For comparison, the lowest sound the human ear can detect is 10,000 milihertz, meaning we will never hear the hum of the Earth, or the sounds that are likely made by Venus and Mars in similar fashions. While our sister planet, and the red war god waltzing about the sky both fail to feature oceans, they are geologically unstable enough to produce a similar effect, geologists believe.

We’ll even throw in a free album.
