Redirecting sound and echolocation is almost a similar process.
Explanation:
Redirecting sound means when the sound gets reflected or bouncing it off of a material or a surface.
Echolocation is the use of echoes and sound waves to find the objects which are present in the space. Bats are sending out sound waves from their nose and mouth to echolocate. These sounds will hit the objectives and produce echoes. The echo reflected from the object and return to the bat's ears. This is how bats are finding obstacles in their path.
