First off no WWII sub was stable enough to sit at periscope depth with the engines off; it would start to either rise or sink fairly quickly. Try the NYGM 'Anti-Hummingbird Mod'-it works like real life.

That said, periscope depth is a grey area. Hydrophones have problems with surface distortion, and a destroyer can't hear (or ping, for that matter) an aircraft carrier, and its propellors are as deep or deeper than a sub's at periscope depth (well, maybe not quite that deep but still...). On the other hand I've never heard of a sub hiding at periscope depth, so I would say they could hear things there.
