Echolocation is the process of using sound waves to locate objects that may be invisible or at a distance. Some bats use sound to locate their insect prey. Bats have vocal chords modified to emit the high-frequency sounds needed for good resolution and...

Echolocation is a physiological process that some animals use to gain information about their environment. By emitting and detecting its own sounds reflected from objects, animals can avoid obstacles, find food and communicate with others. Echolocation...

Echolocation, also called Biosonar, is the biological sonar used by several mammals such as dolphins, shrews, some bats, and most whales. The term was coined by Donald Griffin, who was the first to conclusively demonstrate its existence in bats. Two...

Abstract. We studied the structure of calls emitted by the echolocating fruit bat Rousettus leschenaulti (Megachiroptera: Pteropodidae) while flying inside a free-flight room. The echolocation sounds consists of both single as well as double clicks, with single clicks emitted either in the beginning...

ABSTRACT.- Among different bat species, echolocation call structure varies predictably according to habitat use. Much of this interspecific variation in echolocation calls reflects the physical constraints of sound propagation and echo formation in open versus spatially complex habitats. Bats must use calls that...
