Why do some high end component sets make a clicking sound when coasting?

Some can even turn it into a user-created marketing ploy

I loaded up my DT Swiss 240s hub with lots of their special grease. For the first 5 miles or more the pawls were hesitant to engage. That was a PITA until the hub warmed up enough and the grease loosened. After that the hub was a bit quieter and engagement was back to normal.

as someone who doesnt own a loud hub like these, but who does very much enjoy country rides, I wonder how annoying these are---I realize that we dont really coast that often, I dont anyway, so perhaps its a moot point, but does it bother some of you? While riding, I have noticed it on some bikes, to the point that I did think that it would be a drag on a quiet road if not going all the time.
(and I used to race motorcycles and have been around F1 cars, Champ Cars, LeMans etc, so I'm not a no-noise fanatic)

Descends like a rock
When I first got my Velocity wheels it bugged me. My previous Shimano hubs were silent. I hardly notice it now though - funny how your brain starts filtering annoyances like this. Are some of you saying a simple squirt of oil will quiet them down? Oil, or grease?
BTW - I read once that the Velocity Road hubs were actually a rebranded something else - anyone remember off the top of their head what they are?

My dura ace 7800 rear hub has a nice clicking sound.
Not as loud and a different tone than CKs. Always thought
dura ace was a tripawl system also. Some on thread disagree.

If you want it to get even louder, back pedal. It's easier and less dorky than calling out "on your left" when you do a loop around the scenic, but crowded park half way into a long ride.

again another perhaps assumption on my part--does anyone really know the mechanical reason, or rather, why these hubs were designed with the noise in place? Would the mechanism be stronger than a more quiet hub? Is the mechanism a more long lasting/durable/lighter setup than lower end stuff? (these last ideas are what I would figure to be the real reason)

As said above, a lot depends on the hub type. Shimano = quietest and near silent, whereas Chris King = buzz galore. Doesn't necessarily correlate with speed or quality, though.
My Shimano Sora is virtually soundless and I think all of you would rather have a noisier SRAM or Campy setup.

Noisy hubs are really annoying, IMO. I prefer them quiet. Silence isn't necessarily, but the classic Chris King buzz drives me crazy. I've actually got CK hubs on my road wheels, but they're the newer R45 (?) model, and the buzz is tolerably quiet on them.

some of it is the number of pawls.
shimano = 2
campagnolo = 3
hugi = 4 (i think)
volume goes up in the same order. all things equal, more pawls=stronger
then you also have hubs like chris king that have a buzzing "ratchet style" mechanism.
so yes, it is a side effect of a particular design. as a result, it also gives brands a distinguishable tone. campagnolo and chris king are both loud, but completely different tones.
cars are the same way. porsche flat 6s, ferrari v-12s, and small block v8s all have a distinguishable noise due to design. ford and chevy v8s even have distinguishable sounds due to firing order. it was not designed for this, it is just a natural side effect.

I love loud hubs. Very good for when you're near other cyclists, pedestrians, squirrels, etc.
They do tend to scare old people, so beware.
