Echolocation : Explanation

Introduction

Echolocation is a unique process of sound that is repeatedly used mainly by many animals to help to avoid/detect danger,obstacles or food/water. Animals such as bats, marine mammals, rodents even humans.

Body:

A bat is a perfect example of echolocation. When a bat travel through pitch-black caves, they use echolocation. Bats sends vibrating signals which can either bounce back to the bat or carries on until they reach an object then bounce back. If the vibrations bounce back fast that means there are objects ahead so they avoid it but if it doesn’t come back until it reaches a nearby object the bat goes ahead until they reach that objects. Bats also use echolocation to hunt insects or food. Bats use their ears as eyes. They send the same vibrating signals which bounces of an insect then back which tells the bat thats its a prey. Echolocation helps humans too. They use ultrasound to check if a baby in the mothers stomach and to detect animals in seas and rivers.

Conclusion:

Try yelling in a cave can you hear your echo. The vibration of your vocal cord vibrated throughout the cave then back to your ears where the brain translates it back into sound. Many animals rely on their ears instead of their eyes.
