Our dream house is nearly complete - we move in next week.
But the buzz from the fluorescent lights (we used a lot of them)
sounds like the house is a model airplane taking off.
We *have* to fix it.
I isolated all the ballasts from the fixtures so the fixtures aren't
vibrating, but that only reduced the noise by less than a dB, if at all.
The buzz is coming from inside the ballasts.
Is there anything I can do to improve it?
Is there a company with enough pride to make ballasts vacuum-potted
(or whatever) well enough that they don't buzz?
These mass-produced consumer ballasts are for the birds,
and sound like the bees.

Replace the coil ballasts with modern electronic ballasts.

Make sure the electronic ballast is of high quality. Also if you have radio receivers near by, these devices can cause lots interference.
