	In the case of my small coil here (30" streamers, 12 kV, 60 ma NST) the
gap contributes most of the noise.  When I run it using my old Amrad
quenched gap (which is almost completely silent) the high-frequency
noise disappears and all I can hear is a loud buzzing and "sizzling"
sound, which probably doesn't carry very far and isn't particularly
annoying.  Might not be true for bigger, higher powered or more
efficient coils.
