Sentences with phrase «echolocation for»

It makes sense: Humans have been perfecting sonar for more than a century, but evolution has been honing echolocation for much, much longer.

Not exact matches

Bats have good eyesight and most use echolocation (a series of sound waves) to search for food.

Human echolocation shares some similarities with animal echolocation, though people use the skill to compensate for their sight, rather than as an additional sense.
A better understanding of echolocation may improve methods for teaching the technique to people who have lost their sight later in life, and yield additional insights into human hearing.
But for individuals who became impaired later in life, echolocation training can help them to move through the world with greater independence and safety.
This illusion, thought to be based on the lifter's cognitive expectations, and the fact that it is also present in blind echolocators, but not in blind non-echolocators, shows that echolocation is an effective form of sensory substitution for vision.
Dolphins are famous for their ability to hunt prey via echolocation.
The results, published in the journal Functional Ecology, show that the bat's echolocation calls were high in frequency but low in intensity making it difficult for the insect to detect the imminent danger.
«In effect, the echolocation of Pallas's long - tongued bats is too quiet for the moths to hear and allows them to sneak up on their target using a stealth tactic.»
To test the extent to which people can compensate for this immobility, Wiegrebe and colleagues recruited eight undergraduates with normal vision to don blindfolds and learn some basic echolocation skills.
Still, neurobiologist Constance Scharff of the Free University of Berlin in Germany notes that to really make the case for a role of FOXP2 in echolocation, functional studies are necessary, such as knocking out the gene.
That was also the case for two kinds of bats and toothed whales, a group that includes dolphins and certain whales, that have converged on a specialized hunting strategy called echolocation.

Blind is a narrative - driven psychological thriller for virtual reality where the player is blind and must explore their surroundings using echolocation.
Looking at how bats use echolocation and decoding how it's done is bringing scientists closer to better ways of using sonar for everything from maneuvering robotic vehicles to finding flaws in building structures.
Lead author Simon Whiteley from the Centre for Ultrasonic Engineering at the University of Strathclyde, said, «We aim to understand the echolocation process that bats have evolved over millennia, and employ similar signals and techniques in engineering systems.
