People are capable of echolocation too. They must be Battleship masters.

Despite the limitations, Daniel Kish shows that his ‘FlashSonar’ is actually, in some cases, far more effective than the visual input that we receive. His method of echolocation grants him a three hundred and sixty degree view of his environment, with it working almost as well behind him as it does in front. He can ‘see’ around corners and the sound also works through surfaces- it is, in a way, almost like having X-Ray vision.
