Models for shot-noise events which produced radio noise during the crossings of the Saturn rings by the Voyager 1 and 2 spacecraft are presented. During the Voyager 1 crossing the electrostatic noises appeared within the 1.2-154.8 kHz bands, and were determined to be confined to the inner region of the E-ring. The Voyager 2 crossing encountered lower frequency noise in the G ring in a region of about 70 x 700 km volume. Investigations of the effects of electrons and ions collected by spacecraft and/or emitted by antennas showed that impacts of electrons and ions can explain the observations of Voyager 1. A quantitative examination of the power spectrum of the signals received by Voyager 2 indicated that grains must be considered as sources of the shot noise. The average dust size is estimated at 2.3 microns diam.
