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?

The way I interpret J.C.'s post, I believe when he wrote "0.000000000000000000001 mile/minute." he was referring to the level of precision of measurement of sound velocity, not the actual velocity of sound.
And SONAR converts sound information to a 2-D visual image, whereas the problem asks for a "hearing aid type device"
