The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats.

Bats use ultrasounds to navigate in the darkness. A dog whistle, which emits sound in the ultrasonic range, used to train dogs and other animals. Bats use a variety of ultrasonic ranging (echolocation) techniques to detect their prey. They can detect frequencies beyond 100 kHz, possibly up to 200 kHz. [16]
