Here are selected samples of different types of radio noise detected by the Radio JOVE system.
S-bursts (short bursts) have durations of a few thousandths to a few hundredths of a second and can occur at rates of tens of bursts per second. Groups of S-bursts sound like popcorn popping -- or like a handful of pebbles thrown onto a tin roof. S-bursts are often associated with the Io-B or Io-C source (sources that are influenced by the location of the Galilean moon Io).
L-bursts (long bursts) last from a few tenths of a second to a few seconds and sound like ocean waves breaking up on a beach.
On occasion the Jovian activity is a mix of L and S-bursts.
Solar bursts typically last from half a minute to a couple of minutes and often sound like a rapid increase in the background noise (hissing noise) followed by a gradual decrease back to the original baseline level.
Glactic Background Radio Noise is caused by relativistic electrons spiraling in the galactic magnetic field.
