Normally, if you hear a sound, you have some idea of where the sound came from. But when a scuba diver hears a sound underwater, it is virtually impossible to tell where it came from.

1. Why?

2. Can you suggest some form of underwater hearing aid type device that would allow more accurate underwater sound localization?

Jonathan Chang, the speed of sound in water is considerably more than 0.000000000000000000001 mile/minute.
And there is technology available to identify sound location.  If I'm not wrong, it exists since 1916 and is called SONAR.
