We know this already, and we should be quieter. OTOH, with ships slowing down because of oil costs, its likely to be quieter. Also, better propeller designs to save fuel will cause less cavitation and noise.
I have a nit, though: the whales _could_ have been this noisy, but they only "talk" loud enough to be heard. If they didn't need to shout over the engines, then they needn't have been so noisy?
