It’s not black or white - on the range of vision and echolocation in echolocating bats [PDF]

Frontiers in Physiology, 2013
Around 1000 species of bats in the world use echolocation to navigate, orient and detect insect prey. Many of these bats emerge from their roost at dusk and start foraging when there is still light available.

Wireless recording of the calls of Rousettus aegyptiacus and their reproduction using electrostatic transducers [PDF]

, 2010
Bats are capable of imaging their surroundings in great detail using echolocation. To apply similar methods to human engineering systems requires the capability to measure and recreate the signals used, and to understand the processing applied to ...

When echolocating bats do not echolocate [PDF]

Communicative & Integrative Biology, 2008
Echolocating bats are known to continuously generate high frequency sonar pulses and listen to the reflecting echoes to localize objects and orient in the environment. However, silent behavior has been reported in a recent paper, which demonstrated that the big brown bat (Eptesicus fuscus) can fly a relative long distant (0.6 to 8 m) without ...

6-hour Training in click-based echolocation changes practice in visual impairment professionals

Frontiers in Rehabilitation Sciences, 2023
Click-based echolocation can support mobility and orientation in people with vision impairments (VI) when used alongside other mobility methods. Only a small number of people with VI use click-based echolocation.

Biomimetic echolocation with application to radar and sonar sensing [PDF]

, 2014
Nature provides a number of examples where acoustic echolocation is the primary sensing modality, the most well-known of these being the bat, whale and dolphin. All demonstrate a remarkable ability to "see with sound".

Collicular Responses to the Frequency Modulated Final Part of Echolocation Sounds in Rhinolophusferrum equinum [PDF]

, 1971
Collicular evoked potentials in Rhinolophus ferrum equinum show very prominent responses to the final frequency modulated part of a acoustic stimulus, simulating the natural echolocation ...

Clicking in Shallow Rivers : Short-Range Echolocation of Irrawaddy and Ganges River Dolphins in a Shallow, Acoustically Complex Habitat [PDF]

, 2013
Toothed whales (Cetacea, odontoceti) use biosonar to navigate their environment and to find and catch prey. All studied toothed whale species have evolved highly directional, high-amplitude ultrasonic clicks suited for long-range echolocation of prey in ...

Echolocation in humans: an overview [PDF]

WIREs Cognitive Science, 2016
Bats and dolphins are known for their ability to use echolocation. They emit bursts of sounds and listen to the echoes that bounce back to detect the objects in their environment. What is not as well‐known is that some blind people have learned to do the same thing, making mouth clicks, for example, and using the returning echoes from those clicks to ...

Instrumented transducer for study of the bat echolocation process [PDF]

, 2009
Evolution has enabled the bat to echolocate with ease and efficiency, to the extent that the bats capabilities far exceed the most technologically advanced manmade systems. Such capabilities reinforce mans intrigue in the animal kingdom. In studying bats
