the fixing of the position of an object by transmitting a signal and measuring the time required for it to bounce back, typically done by radar or sonar and by bats. echometry the measurement of the duration of and intervals between sounds. — echometer, n. ...
Among the most highly refined applications of the auditory sense are those found in such animals as bats and dolphins. These creatures are able to discern objects around them by a process called echolocation; the animal sends out a cry and, by the nature of the echo, is informed of the pr...
sound is also possible, as that which is perceived by the ear, but such a definition is not particularly illuminating and is unduly restrictive, for it is useful to speak of sounds that cannot be heard by the human ear, such as those that are produced by dog whistles or by sonar ...
The reflection of sound is used by some animals, notably bats, for echolocation — locating, and in some cases identifying, objects through the sense of hearing rather than the sense of sight. Bats emit bursts of sound of frequencies far beyond the upper limits of human hearing. Sounds with...
Sound waves are used in a variety of important ways by animals and humans. Animals, such as bats, can use echolocation and sound wave vibrations to locate objects in their paths. Humans use sound waves to share important ideas and feelings. Sound waves allow you to hear funny jokes, but ...
This year they are featuring somenewactivities such as:Timber! Sunday Brunch at Pete’s Club Grill,The Ashley Memorial Seattle to Timber! Bike Ride, Bat Viewing & Listening Party with Bats Northwest and much more to be announced. During the day, the Main Stage invites campers to enjoy music...
Dolphins, whales and bats can make such high-frequency sound. It does no harm to health. Sound less than 20Hz is called infrasonic(次声)waves. When we move, the air will vibrate. The vibration of air can produce infrasonic wave.As the frequency of infrasonic waves is close to that of ...
被反射:被重复反射,如声波、热或光A concentrated layer of organisms in the ocean that reflects and scatters sound waves, as from sonar.散射层:海洋中反射及分散声波的,如来自声纳的生物体密集层Like bats, they send out sound waves and make sense of their environment from the echoes they receive ...
What is meant by resonance? What are the conditions for resonance to occur? Bats hear using . Describe how a wave is different from a pulse. If a tree falls in a forest, and no one is around to hear it, how do you know that a tree fell?
