Being 'pinged'

Well, I certainly wouldn't consider it a case of mere ambiance. The scenario I mentioned was a one shot deal and I haven't had a similar situation since. In most other cases, I had serious cause for concern when being pinged. The point is that, being pinged isn't necessarily a death warrant. They don't necessarily know your exact location and you still have evasive maneuvers to assist your departure from the vicinity. Like Sailor Steve said, you'll know for sure by the proximity of the DCs their discharging.
I once got DCed but they were being dropped hundreds of yards away from my actual position. They'll know for sure that a sub is probably around when their ships start to spontaneously explode. A torpedo wake, spotted periscope and a ping or two help them narrow things down.
