I'm afraid that TV shows rarely have specially composed sound effects for everything. There are a large number of commercially available sound effects in existence. Most Sound editors ( like me ) have access to only some of them - they are very expensive and TV productions do not want to fork out for more than they can get for free. A select few will give you the time (I.E. money) to source and create their own signature sounds, but the bulk of the rest (doors, atmos, cars, creaks, skids etc.) will be from libraries.
It was ever thus, of course. Many of the sound effects i that we know from "The Prisoner" (1967) or "Thunderbirds" are iconic now because of there association with these shows, but were commonplace in TV and films of the period. - For example - the interior of the observation room in "The Prisoner" has the same electronic rotating hum as in Kinnear's house and garden in "Get Carter" made six or seven years later. Or the distinctive doors on the Starship Enterprise become The Computer Proteus's multi purpose 'arm' as it menaces Julie Christie in 'Demon Seed'.
These Sounds are created for a job, then put on a drive or shelf until another Dubbing Editor finds them and thinks it will be good for something entirely different. A kind of creative recycling if you like.
That is why I cringe when the TARDIS door opens or when they use that klaxon in Dr Who. Very familiar sounds to me and a number of people in the industry. But it would be prohibitively expensive to do a soundtrack for most things any other way. And it has an added bonus that you often hear your own sounds on another show being used for something entirely unconnected. Which is nice. If only we got royalties!
Nobody agrees?
