Echolocation By Noelle Lefevre

What is echolocation?

Echolocation is the use of sound waves that certain animals use to detect/locate certain objects. It is mainly used for navigation, communication, hunting, and avoiding predators.

How does echolocation work?

The animal using echolocation can send high-pitched sound waves to determine where an object may be. The sound wave hits the object, bouncing back, returning to the animal. It is a very helpful ability to have for survival.

What animals use echolocation?

Echolocation is used by bats, dolphins, and whales. Yet, scientists do not know if all whales have echolocation abilities. In some cases, certain rodents like shrews can even use echolocation.

How bats use echolocation: Bats send sound waves from their mouth or nose. With their large ears, they receive the sound waves that have bounced back from that certain object or animal. N. p., 2017. Web. 15 Feb. 2017.

How dolphins and whales use echolocation: Dolphins and whales send sound waves from air movements in their nasal passage. Dolphins make whistles and clicks like squeaks, grunts, groans, trills, and many more sounds that may resemble many different emotions. Whales make pulsed click sounds when they communicate, hunt, or navigate. N. p., 2017. Web. 15 Feb. 2017.

Can we use echolocation?

Actually, some blind people have been able to use echolocation. Experts in this ability have been able to sense the size, shape, and material of objects by listening to their echoed mouth clicks. Blind people will tend to be better at it than those who aren't blind, but anyone can learn it. Echolocation just isn't exactly necessary for us unless you're blind, then it can be pretty helpful.

Here is an example of how humans use echolocation: N. p., 2017. Web. 15 Feb. 2017.
