Where did the original Enterprise bridge sounds come from?

I was watching an episode of The Adventures of Superman , specifically Stolen Elephant made in 1957 and there was a short scene with background sounds that were very close to the sound loop used for the bridge background sounds in Star Trek . (Loop of bridge sounds here.)

Anyone who was watching TV in the 1960s and 1970s heard this sound loop re-used in shows like Mission: Impossible . (And I think I remember hearing it used in Buck Rogers in the 25th Century , but I'm not sure.)

Was this sound loop created for Star Trek originally? Or had it been used previously? Is there any documentation on where it came from and how it was made? If it was used before Star Trek, where was it used and when was it made?
