Simple household foley like this has been a staple of radio drama, film and games for decades because a door tells the audience someone has arrived or left without any dialogue. Short open and close clips spread widely through royalty free libraries and video editing packs, and creators now drop them into skits, animations and gameplay edits for instant spatial clarity. It is often paired with a door knocking sound effect to build a complete entrance sequence, which keeps the sound useful even as editing styles change.
