Tinton Falls, N.J. Lines: 16 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?
