Earth is not a quiet planet. It transmits a rather hideous sound [flash] into space that is 10,000 times greater in strength than any man-made radio transmission. The Earth also quietly hums with seismic Love Waves (hear them), while the Magnetosphere is alive will all sorts of sounds (check out the creepy-sounding Chorus Emissions). Also, stars sing out in middle C before they explode as supernovae, and the Perseus Cluster black hole has droned a B-flat for the past 2.5 billion years.
