This is the sound that myself and others agree is what you hear when a loud noise makes your ears ring. Why this particular frequency? i don't know. It's just a simple generated tone--you can loop it to make it longer.
I wanted to have a decent ring tone sound, not something too cheesy and also something recognisable, thus i spawned this baby from a parody of a tsfh track.
