Not necessarily 3500 times the energy to create it, and it's an inverse, not an inverse-square relationship. That's beside the point anyway. Because sound travels further and faster underwater, we need to be careful that the things we put in the ocean. We already know that there are sound pressures that will burst the human eardrum. A whale's lungs act as a tympanic membrane when enough pressure is exerted - and those can be burst too - with more lethal consequence for the whale than the human concert-goer with the burst eardrum.
