Echolocating bats of the genus Rousettus produce click sonar signals, using their tongue
(lingual echolocation). These signals are often considered rudimentary and are believed to …

Echo-locating bats constantly emit ultrasonic pulses and analyze the returning echoes to
detect, localize, and classify objects in their surroundings. Echo classification is essential for …

In this paper, we study echolocation by spectral analysis as a biomimetic, ie, inspired by
bats, mechanism to observe a realistic environment. We propose a method to localize, ie, to …

Computational models of animal biosonar seek to identify critical aspects of echo processing
responsible for the superior, real-time performance of echolocating bats and dolphins in …

Their sonar system allows echolocating bats to navigate with high skill through a complex,
three-dimensional environment at high speed and low light. The auditory analysis of the …

For decades, researchers have speculated how echolocating bats deal with masking by
conspecific calls when flying in aggregations. To date, only a few attempts have been made …

Up to now, low-frequency ultrasonic transducers have been manufactured using different
materials and technologies and have been inspired by the biological world, mainly by the …

The big brown bat, Eptesicus fuscus, navigates and hunts prey with echolocation, a modality
that uses the temporal and spectral differences between vocalizations and echoes from …

Big brown bats (Eptesicus fuscus) emit wideband, frequency-modulated biosonar sounds
and perceive the distance to objects from the delay of echoes. Bats remember delays and …

Big brown bats transmit wideband FM biosonar sounds that sweep from 55 to 25 kHz (first
harmonic, FM1) and from 110 to 50 kHz (second harmonic, FM2). FM1 is required to …
