I heard older TVs being turned on and off as well as CRT monitors. Now, its that very range I 'hear' all the time. Part of me wonders if it was sensitivity to that spectrum that damaged my hearing when I was around multiple CRTs so much.
I have known people that have it much worse than I face daily.
Yeah, for me it sounds almost exactly like the squeal that CRT TVs make. Like, it's basically indistinguishable from that for me.
