PPT-Echolocation

What is echolocation The ability to locate an object in space by emitting a call and monitoring the soundwaves being reflected back to you The frequency of the sound emitted is related to the frequency of the sound returned so one can recognize ones own call. Love into bats. The slideshow. . Never regret it.. Chapter 1: Bat bodies.. Bats sometimes have strange bodies.. They have long fingers on their wings. Their ears are big to hear their echolocation. Their feet are so small their smaller than a mouse! Their nose looks like a pig nose only smaller. And when their wing rips it quickly grows back.. Mammalogy. . (. Spring 2014 .

Flying squirrels are usually found in North America, where there are tall trees. . The Siberian Flying Squirrel ranges from the Baltic Sea in the west to the Pacific Ocean in the east. By: Sarah Kuenkel. Dolphins’ echolocation is helpful and amazing in many ways. They use echolocation to communicate just like people use words to communicate. Echolocation is a sonar system. . They release a focused beam of clicking sounds (sound waves) and then listen to the echo. From this they can tell what an object is (fish, shark, other dolphins). They can tell all of the characteristics such as size, shape, distance, speed, direction, and internal structure.. Wave. particles vibrate parallel to the direction of the motion of the wave. Terminology. Compressions. : areas where particles come closer together. Rarefactions: . regions where particles are further apart. 10 Bat Algorithms Xin-She Yang, Nature-Inspired Optimization Algorithms, Elsevier, 2014 The bat algorithm (BA) is a bio-inspired algorithm developed by Xin-She Yang in 2010. 10.1 Echolocation of Bats Although bats and dolphins live in very different environments, are vastly different in size, and hunt different kinds of prey, both groups have evolved similar sonar systems, known as echolocation, to locate food and navigate the skies and seas. While much research has been conducted over the past thirty years on echolocation in bats and dolphins, this volume is the first to compare what is known about echolocation in each group, to point out what information is missing, and to identify future areas of research.Echolocation in Bats and Dolphins consists of six sections: mechanisms of echolocation signal production the anatomy and physiology of signal reception and interpretation performance and cognition ecological and evolutionary aspects of echolocation mammals theoretical and methodological topics and possible echolocation capabilities in other mammals, including shrews, seals, and baleen whales. Animal behaviorists, ecologists, physiologists, and both scientists and engineers who work in the field of bioacoustics will benefit from this book. Bats and echolocation. Bats - Order “Chiroptera” = Hand Wing. TOC. Don’t nest in hair. Not blind. Scaring the bats in the attic. Most N. American eat insects - lots. They have the same bones in their hands that we do. Echolocation, also called bio sonar, is used by several kinds of animals, such as bats, dolphins, and whales, that need sound to locate food or determine the environment. . They put out sounds and listen for them to echo back, so they can locate and identify objects, such as food, and their surroundings. . What makes sound:. . Vibration makes sound. When you talk it causes vibrations which goes to the other persons ears. . . How does sound travel?. Sound travels with sound waves. . What can sounds go through?. Hearing Impairments. Lets Read our Student Issues, Page 6. “Supersonic Ears”. The special sense of hearing that bats use is called echolocation. Dolphins and whales also use echolocation, but the sounds they make are much lower than the high-pitched sounds that bats make.
