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 answer is simple. Since the speed of the sound in the air is five times faster than the speed of sound in the underwater, the sound reaches both of our ears almost at the same time. It is difficult for our ears to identify where the sound comes from due to the fast speed of sound. As a result of the super fast speed of sound in the underwater, there is no device to be so advance to be able to detect accurately the speed of the sound in the underwater. Unless technology in the future is so advance that it could develop a device that can record accurately the speed in 0.000000000000000000001 mile/minute, it could then be able to be possible to use it for our identification of the sound's location.
