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?

There are not many constant sounds.  I haven't tried it, but quite possibly its harder to localize constant sounds. Also, at 1/2000 of a second you quote, a sound with a frequency under 2000 Hz will have a phase relationship that can be used.
