The audio "Jovian chorus" was recorded by University of Iowa Plasma Wave Group. It is generated in Jupiter's radiation belts by electrons spiraling along Jupiter's magnetic field lines in this region. Once generated, the chorus waves interact with the moving electrons, disturbing the spiral orbit of the electrons and causing them to fall into the Jupiter's ionosphere along the magnetic field lines at high latitudes. Chorus waves consist of a rapid succession of intense ascending tones, rising in frequency over very short time intervals, each tone lasting typically less than one second. The frequencies of these rising tones occur in the audio frequency range and sound like a dawn chorus of chirping birds, a sound which gives these waves their name.
