Some mammals, like most toothed whales, have echolocation abilities. Dolphins can emit short calls that last tens of microseconds and have a frequency greater than 100 kilohertz. The appearance of this sound is related to special air chambers located in the nasal passages. The frontal crest on the dolphin's head acts as an acoustic lens, transsforming the received sound waves into a narrow sound beam. The dolphin determines the direction and distance of the object based on the reflection of its own call from the object in the water. . The frequency of repeated calls made by dolphins increases as the distance to the target decreases. So you can use this sound detection to freely cross obstacles or catch food without using vision or other senses. Its echolocation system not only has good distance and direction resolution, but also has a very strong ability to identify targets and judge the shape and material of objects in the water. Therefore, the study of dolphin echolocation system is of great importance to the development of sonar. A variety of toothed whales can make sounds and whistles of varying pitches, with frequencies ranging from 1,000 to 10,000 Hz. This call varies depending on the species and humor and serves as a communication function. The baiji dolphin, a rare animal native to the Yangtze River in China, also possesses the ability of acoustic communication and echolocation. The sounds made by large baleen whales are generally below 400 Hz, or as low as 20 Hz, and can be used for communication purposes. Seals and sea lions can also emit barks and short pulses of sound in the water, and have some acoustic communication and echolocation functions.
