Place it at a scene change, right where one lesson or activity ends and the next begins, then follow it with the Bell Ding Sound Effect for a second classroom cue before the new scene starts.
關於此聲音
This is a clean electronic bell chime lasting about fourteen seconds, sounding in an even, no-nonsense pattern rather than a tune. It feels instantly familiar and a little tense, like a signal that time is up and everyone has to move. The sound is associated with Bodet timing systems used for scheduled bells in French schools and buildings, which is why it carries that sense of routine and school-day nostalgia.
