Epoxy didn't really work for me. Instead I bought a project box, densely filled it with foam and put the EL power supply inside - it barely makes any sound now.

For ease I soldiered a toggle switch to the outside of my box + removed all the battery housing and use a DC adapter instead.

Oh leave it in its casing when you wrap in foam or your foam will smolder (toxically)

Huh, I have had this problem, never thought of that. Wonder if epoxy might not be better, just thinking of heat issues as your using hot glue. But, then again its probably not on for long

I thought this was about silencing high freq leakage >.<

All good though, cos xformer buzzing can be quite annoying :)
how does it make it quieter?

As a noise is created the noise is carried "in" the air, moving the air back and forth. The glue decreases the amount of air movement making the transformer quieter.
