Yes, the Le Creuset will grumble and then quiet down right before boiling. I use it when I want a whistle.
I also have a Bodum stovetop kettle. This one will boil faster than the Le Creuset. As I said, it has some sort of rapid boil design that I don't understand. It will grumble and pop, and sort of groan before boiling. It make a bit more noise on the stovetop, but there is no whistle. I use it when I want to make hot water quickly, such as my morning coffee french press.

BTW, Bodum Bistro makes the best burr coffee grinder. It uses some sort of anti-static glass for the ground coffee to collect in.
