How Does Echolocation Work?

Echolocation is when animals locate objects using sound. Bats, dolphins, and other animals use echolocation. First, the animal makes a sound, which is usually high pitched. This helps the sound travel farther and also give it more energy. Then, the sound reflects or bounces off of a surface or another animal. Then, the sound reflects back to the animal’s ears and the animal is able to identify the shape of the object and also how far away it is! This is really helpful for animals that live in the dark or can’t see well. Animals need good ears to use echolocation. That is what echolocation is!
