guys, the beeps are just from a sound effect used a lot on old tv shows. that’s why it sounds so familiar to everyone. above should take you to the 3 minute mark, you can hear it in the background softly with other beeps layered over it. that’s the closest I could find after going through like a hundred videos. the last place I heard it loud-and-clear was a Wonder Woman re-run. but I know this particular sound effect because my dj mentor had it on a record and he used it in his scratch mixtape that I listened to a hundred times.
in the op videos, they make each one different by sampling it off-measure and looping that and/or chopping the sample in other ways.
now, how the hollywood foley artist generated it in the first place is probably answered by one of the above posters’ methods. but the op videos are just getting it from a sound effect library.
