The TV noise you used to hear is gone because CRTs are gone-- it comes from the flyback tranformer in the TV, which had a propensity to resonate at the TV's horizontal scanning frequency (somewhere in the ballpark of 15.7 kHz, the exact frequency depending on whether your TV was NTSC or PAL).
I had a "I haven't heard that in ages" moment over the summer; was in some shop in the UK that had a CRT showing their CCTV cameras and could hear the thing well before I could see it. Apparently my high-end hearing's still decent.

Here's an example of what they look like at tournaments [1] [0]: https://old.reddit.com/r/smashbros/comments/3dzqd9/to_those_who_enjoyed_smash_at_evo_please_thank/ https://old.reddit.com/r/smashbros/comments/3dzqd9/to_those_...
