It replaces my ring bell.

Like I always say to my friends: if you hear your freehub too often, it means that you're not pushing enough. Andale andale!

Good thing about loud hubs is that you can quiet them down pretty easily by adding extra grease inside the freehub body and on the gears. Some people do try to do the opposite though and I have concerns with not following the manufacturer's instructions since it can become a safety hazard.
