Dont forget sound travels further and faster through a liquid or solid than it does in gas (air) also a worthy note SOSUS the nets pin pointed K129 when she exploded in unknown circumstancies the nets were a good thousand miles away same with K219 scorpion and many other subs and ships.

Very true....a friend of mine (sadly departed last month) was a PO Sonar on British subs and he told me they could pick up and identify from their individual sound signatures what liners were leaving the US Eastern coastal ports such as New York whilst lurking off the western coast of the UK. |
Don't take this as an absolute though, it completely depends on acoustic conditions which change frequently. In absolutely perfect conditions is where this kind of stuff is possible. In absolutely terrible conditions a submarine with a decent sonar could still end up colliding with something that is loud. The way sound works in water is weird.
