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 & Foschini 1999) we find that Leonid meteoroids more massive than about 0.1 kg can potentially generate short duration electrophonic bursters.
