What's the pressure difference on your ears between 40ft and 70 ft ?
It will be the same as your other body parts and everything else around you.
Sorry I couldn't resist that one......

He didn't say 'on scuba'. He could be talking free-diving.If you are clearing properly the answer is 0. Pressure difference between the inside and the outside of your eardrum is what causes pain, if you are clearing properly there is no differential pressure, reguardless of depth. Now if your asking what is the diffenence in ambient pressure on the body between the 2 depths, see above.

Herman is right.
What possible difference would scuba vs free diving make on the pressure difference?
