The bike mechanic that listened to it said it was normal, some are louder than others, but this is really loud. Would opening it up and adding more grease make it quieter?
New ears, huh? Congratulations!
In my experience, different hubs make different amounts of noise, Without knowing which hub we're dealing with it's had to say, but as long as it makes a ratcheting noise it's probably OK. If it goes quiet unexpectedly you could be heading for trouble. On the other hand, if it goes quiet and quits driving the bike forward, well, there's your sign.
If the bike's new, I'd let it break in. Many hubs get quieter with use. If you really want to quiet it down, overhauling the hub and running heavy oil through the freewheel mechanism can make for a very quiet rear hub. This involves a complete rebuild, though- if it's not needed then I wouldn't mess with the hub.
