Indeed, and moreover, the ability to detect underwater sound is probably aided by the lack of localized turbulence (wind noise in microphones) and the degree of sophistication sought after by navies due to the detection and counter-detection of military submarines. Without any actual knowledge, I imagine that a ship or sub could be festooned with hydrophones, enabling it to detect faint noises, but also to determine their direction from phase information.
