Shimano sneaked an engineer into the Campy factory several years back. The freewheel noise is so that Shimano riders can keep track of Campy riders in the pack. The loud CLUNK shifting sound is so that Campy riders can't surprise Shimano riders with sudden breaks. You hear the CLUNK, you know they're about to accelerate.

Anyone know how many engagment points record freewheel/hubs have?

I think it depends a little on what sort of bike you have. The noise probably resonates more with a steel, al or ti bike, and is deadened a little with carbon.
Or that's the theory from a friend with a carbon bike and more quietly ticking wheels.

I've never noticed a difference on my AL and steel bikes or my buddies Carbon. I always tell people it's Italian Morse code to start pedalling.

I recently replaced a new chain/cassette and used the 'opportunity' to break own the Chorus hubs and re-lube. Obviously, lubing the bearings, but glopped grease on the pawls. Very quiet, so much so that I could hear others clicking - and they mostly had Shimano based wheels. After several hundred miles the click is becoming more noticable, but no where near the previous noise. Previously, just walking the bike would get stares from the clicking.

All Campagnolo / Fulcrum freehubs have 3 pawls so, 3 engagement points.
The noise is because Campagnolo uses a super high end German grease that has the consistency of melting butter. If you use too thick a grease on your pawls, it can cause them to stick to the freehub body and not engage. This is true of any freehub.
If you don't like the sound of a Campagnolo freehub, here's what you can do. Remove the freehub and place a bit of FinishLine Premium grease behind each of the pawls (in the cavity behind the pawl). This ensures you don't use too much grease but just enough to make the freehub run very quietly.

You get used to it... Or, maybe you just go a little bit deaf.
Oh, and that loud "clunk" sound you hear when the Campy guy is shifting is him dumping three or four gears as he stand to accelerate past you like a rocket ship. All the other guys are going, "click, click, click, click" as they yell "Wait up! I'm coming!!"

I ride Vento wheels on my bike and they are also noisy when coasting, but I also have a pair of Velomax/Shimano wheels that I'll put on occasionally. I'm always amazed at how quiet the Velomax are, even with the Campy shifters. The only problem is that the cog spacing is different and I lose one cog. With 10speed I shouldn't care.

You try walking into the R&D department of ANY company and see how far you get. Not to mention a company that is as secretive about product development as Campagnolo is. Geeze.

Zipp freehubs are very loud as well.
It's a marketing tool to get everyone to look at the wheels.

I have a Easton R4 freehub on my bike and I find it to be quite loud compared to the Shimano it replaced. There's been times coming back into my development on Saturday mornings where I felt like a nuisance as they were so loud. I think after a few hundred miles they may have quieted down or my I might be getting hearing damage from the stupid thing.

My main bike has Shimano, and I used to love the "stealth" aspect of it: I could sneak up on other riders and scare the living crap out of them trivially.
But the fun in scaring the living crap out of someone is short-lived; it's way more useful to announce your presence effortlessly and elegantly. My beater/commuter bike doesn't have Campy, but it has 22-year-old SunTour that buzzes like the proverbial herd of angry locusts when I'm freewheeling. It's so much easier just to coast up behind someone and have them alerted to your arrival without needing to ring a bell, blow a whistle, or holler "on your left!"

I think there has been confusion on this thread regarding engagement points and pawls. Campy has 3 pawls. I think most everyone does.
I don't know how many engagement points (ratchet teeth) Campy hubs have, though I know Chris King has some ridiculous 90 or so teeth. Comparing them both side by side, it seems the Chris King hub has between two and three clicks for every one of Campy's.
I wish I could use Chris King on my bikes.

Thanks for the mental imagery!
