Hi,
We recorded electrophonic sounds of Leonids from during the 1998 
Mongolian campaign, and published our results in JGR (Zgrablic et. al. 
J. Geophys. Res. (Space Phys.), Vol. 107, Issue A7, pp. SIA 11-1, CiteID 
1124, DOI 10.1029/2001JA000310, Bibliographic code: 
2002JGRA.107gSIA11Z). However, we are quite suspicious with results 
presented by Price and Blum because they don't provide any proof that 
their VLF signals are indeed produced by meteors.
