Mouth-clicks used by blind expert human echolocators - signal description and model based signal synthesis. [PDF]

PLoS Computational Biology, 2017
Echolocation is the ability to use sound-echoes to infer spatial information about the environment. Some blind people have developed extraordinary proficiency in echolocation using mouth-clicks. The first step of human biosonar is the transmission (mouth

Echolocation in Oilbirds and swiftlets

Frontiers in Physiology, 2013
The discovery of ultrasonic bat echolocation prompted a wide search for other animal biosonar systems, which yielded, among few others, two avian groups.

Exploring Marine Mammal Cognition as a Conservation Tool

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities.

Drivers of biosonar click rates in bottlenose dolphins (Tursiops truncatus) over the West Florida Shelf

Frontiers in Marine Science
Understanding cetacean echolocation behavior is important for effective population monitoring and conservation. Using passive acoustic monitoring (PAM), researchers can listen for the biosonar clicks produced by echolocating animals to estimate both ...

Neuronal activity underlying vocal production in bats

Annals of the New York Academy of Sciences, Volume 1550, Issue 1, Page 37-54, August 2025.
Bats are known for their highly evolved echolocation and social vocalizations. They have been well studied in terms of auditory processing, but their neural circuits for vocal production are far less understood. This review highlights recent progress in mapping neural activity linked to vocalization in bats.

We Go Signaling Into the Night: Describing an Echolocation Signal of an Unknown Beaked Whale (Cetacea; Ziphiidae) off West Africa

Marine Mammal Science, Volume 41, Issue 3, July 2025.
ABSTRACT Beaked whales (Cetacea; Ziphiidae), one of the most diverse families of cetaceans, can be identified by species‐specific, frequency‐modulated echolocation signals. Of the 24 known species of beaked whales, over half have been assigned a unique signal type. A novel echolocation pulse belonging to an unknown beaked whale species was recorded off

Robustness of cortical and subcortical processing in the presence of natural masking sounds

Scientific Reports, 2018
Processing of ethologically relevant stimuli could be interfered by non-relevant stimuli. Animals have behavioral adaptations to reduce signal interference.
