Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena) [PDF]

, 2015
Funding: Det Frie Forskningsrad (MJ)Toothed whales use sonar to detect, locate, and track prey. They adjust emitted sound intensity, auditory sensitivity and click rate to target range, and terminate prey pursuits with high-repetition-rate, low-intensity

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

Frontiers in Physiology, 2013
(Uploaded by Plazi for the Bat Literature Project) 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.

Audition in vampire bats, Desmodus rotundus [PDF]

, 1990
1. Within the tonotopic organization of the inferior colliculus two frequency ranges are well represented: a frequency range within that of the echolocation signals from 50 to 100 kHz, and a frequency band below that of the echolocation sounds, from 10 ...

Echolocation as a Means for People with Visual Impairment (PVI) to Acquire Spatial Knowledge of Virtual Space

, 2021
In virtual environments, spatial information is communicated visually. This prevents people with visual impairment (PVI) from accessing such spaces.
