  We investigate the conditions under which Leonid meteoroids might generate
short duration (burster) electrophonic sounds. A `first order' theory is
employed to estimate the approximate electron number density in the meteoroid
ablation column as a function of time. Using the threshold conditions discussed
in an earlier communication (Beech and Foschini 1999) we find that Leonid
meteoroids more massive than about 0.1 kg can potentially generate short
duration electrophonic bursters.
