Hum of the Earth (Schumann resonance)
At any moment, around 2,000 thunderstorms occur worldwide, producing about 50 lightning flashes per second. These lightning strikes create electromagnetic waves that travel around Earth. When these waves have the right wavelength, they combine and amplify, forming a continuous atmospheric vibration called Schumann resonance.
