As a cyclist, I find sound such a poor signal I'd consider it optional. Too many threats are silent and sound is too late, misleadingly bounces of other surfaces and generally poorly correlated with significance.
Safe cycling is all about vision. If you can't see it's safe, it's not. It isn't simply seeing imminent threats but predicting them e.g. identifying drivers that aren't paying attention and where a car could suddenly emerge like blind turnings, car doors, pedestrians and such, and countering with appropriate caution / road position.
If you find noise useful, IMHO it means you aren't sufficiently aware of your environment.
I cycle every day, and sound is definitely important; you need to plan ahead when you hear an ambulance approaching, for example. Plus, your brain processes things you see much better if there's a sound it can correlate the movement with.
