Suggestions for finding noise I hear while riding

[Grog]

Yes, trying to localize/isolate the problem by trial-and-listen is the way to go.

Does it click (or whatever) when I am pedalling?
When I am coasting?
In certain gears?
In a certain chainring?
In the same gear on either of the chainrings?
Are my laces clicking on my crank?
What if I brake and release, do it stop the sound? (Possible brake rub.)
Is my lock on my rack and rubbing on something?

If it goes psssst! it's a flat tire.

After going CRAZY for weeks I finally figured out that the spoke-protector disk on my bike is vibrating and making awful sounds. I got off the bike and moved the disk with my fingers. Sure enough, that's what was making the sound. It's still vibrating but now I know what it is and it doesn't drive me crazy anymore. I'll get it removed as soon as possible. (I don't want to break it to remove it.)

More suggestions:

Try different pedals

Try different wheels

See if you can create the noise with the bike standing still but torquing the crank with your foot. I've been able to replicate bottom bracket clunks this way.

LOL--one time I heard a sound and it was a clinking sound that troubled me tremendously.

Then I realized it was the keys in my pocket
