"Sounds" of the Magnetosphere. Natural radio waves are associated with lightning, aurora and magnetospheric processes. Some of these radio waves occur at audio frequencies (about 100 Hz to 10 kHz). These radio waves are not sound waves and cannot be heard directly, but a radio receiver can convert eletromagnetic (radio) waves into acoustic (sound) waves with the same frequency so as to allow the magnetosphere to be "heard". 5, record 2, English, - very%20low%20frequency%20emissions
