Ill pop this one in the yarns category but its a genuine question.
Scenario: dive instructor surfaces and says to newbie diver 'OMG, didn't you see the sub go under us at the safety stop?'
The question is whether a scuba diver could hear a military submarine gliding past. Putting aside wake/wash/visibility/pinging, could the diver hear or feel the submarines presence at say 300ft/100m distance.
Part of me says you cant hear them because if you could so could enemy subs in the distance (due to how sound travels under water) ... but on the flip side I suspected the subs stealth relies on being quieter than the ambient ocean noise over DISTANCE and thermoclines?
