Using 'as' as subordinator.

Hi,

Please, is this use of 'as' correct?


As she was listening to the radio, he knocked at the door.

Yes.

Also, "subordinator" sounds like some kind of super villain. (He was once a mild-mannered grammarian, before genetically altered vegetables twisted him into the criminal mastermind known only as 'The Subordinator'!!!)

I would use "while" in that sentence.
