No, don't bother to try it!  The sound energy from a gap is only a few
watts - you won't see any difference in secondary arc length.  Also, the
sound comes from thermal expansion of the heated air.  I think a vacuum gap,
if it works at all, will still waste as much energy through thermal
radiation and conduction even though you can't hear it.  If you really want
a better spark gap, consider running it in pure hydrogen.

By the way, please add your name in future posts so we all know who you are.
