@nathanatmxpc: Go check the original sound and see if you can find this as it is. There's some processing on it, and that's MY work. Besides, I'm mentioning the source even if CC0 doesn't require it, and the original author appreciated the derived sounds. Go study the licences, and do some "extraction" yourself before preaching your wisdom to the whole net.
@luckylittleraven: Cool! :) When I was a kid, the public television here had a quite pompous anthem on an animation panning upwards with abstract antenna-like structures in the clouds, but the following constant sound on the fixed test screen was a poorer, and quite loud, sine wave. :)
It reminds me of the noise you would hear when they stopped transmitting on the television channel (I was a kid). The screen displayed loads of coloured pixels, which later changed to a picture of a little girl, and this was the sound you would hear.
