Need some tuned acoustics in this niche. If something must make a noise, try to make it sound nice.
I hate the harsh sound some hubs have. If I'm behind someone with loud hubs, I might be compelled to either consider rudely passing, or letting them create a larger gap in front of me. Profile Elites are probably the worst. Based on my experience with loud hubs, I agree with the "slow hub" name.
I had some hubs that made a cricket or cicada chirping sound, which was quite soothing, in contrast to the mechanically harsh sounding stuff. No matter how hard I try to relate the CK hub sound to angry bees, it still sounds like metal clacking from within its hollow shell.
I rather have a bell than bring noise. It's more polite. I'm mega impressed by silent hubs.
