So to summarize, a beat per second about as loud as an oil tanker (its engine?) continuing for several hours per foundation - which itself will last decades. The mention of "broadband and continuous sound from an operational wind farm" seems included for creative effect since it leaves the matter of the intensity of such noise entirely to the readers imagination. I would guess it should be of little interest if audible at all to ocean creatures over the sound of waves, even aside from shipping and sonar.
