By "noisy", I mean there's a buzz coming from the drive train. A clean and unworn drive train has a noticeable "buzz", unless there is ample lube to dampen the sound.

I reapply when the chain has that "buzz" that "sounds dry".
I once forgot and rode 1000 miles between lubes and the drivetrain was not noisy.
Okay. Kudos to your lube, I guess. So how can you tell when more lube is needed?
