Dan,
Very good. Yes, I did a search and now understand. It is to bad that such
devices are not fast enough.

I do know that streamers produce most of the noise, though this is not
always fully apparent. The Spark gap still howls quite a bit, especially
air-blast gaps whose raucous action is worsened by the typical vacuum  unit
supplying the air.

Typically ignitrans ARE NOT good for tesla coil work.  The de-ionization
period (shut-off) of the tube is too slow for serious tesla work, however my
friend has got it working good enough to work with his 15kv/120mA 6" coil.
And it is very silent!!!!!

But again, most of the noise comes from the break-out of streamers (not the
spark gap) anyway.

Dan,
Ignatron. Your serious? Care to describe this device?

Although most noise comes from the arc discharges, you can eliminate spark
gap noise by using a Iggy (Ignatron).  My friend
uses these instead of standard spark gap (rotary gaps) for his large coils
and runs the VERY SILENTLY at up to 10kVA input power.

Hi!

Do You know any methods of reducing noise that TC makes?
Thank You for all answers.
