I have a question worthy of the net's collective wisdom.
My hearing extends into the high frequency end (>15kHz).

I can hear several terminals and televisions 'squeal'.
I understand that this is the flyback transformer at the scan frequency.

Is there anything I can do to attentuate the squeal?
How about a coating on the transformer?  Inside the cabinet?
I'm not interested in TEMPEST conformance, just reducing
my headaches.
Isn't there an OSHA limit for such stuff?
