I did a little digging, and it seems that it's not really appropriate to compare underwater decibel measurements with decibel measurements in air. For example, [0] discusses whales that generate clicks at 230 dB, and suggests that that is "equivalent to 170 decibels on land." I'm not sure if it's even possible to get to 240 dB in air... Ah, an article on wikipedia sort of backs me up: [1] says that, at 1 atmosphere of pressure in air, the maximum loudness for undistorted sound is around 194 dB. Anything louder would be a shockwave.
