The research team reportedly succeeded in isolating only vibrations produced by Earth itself from high-precision vibration waveforms observed by multiple seismometers, removing vibrations generated by large ocean waves, electronically generated noise, and so forth. This revealed the fact that Earth undergoes free oscillations at its natural frequencies, ranging from 2.9 millihertz to 4.5 millihertz. https://gigazine.net/news/20171211-earth-humming-noise/
