Dynamics of dolphin biosonar search and detection [PDF]
The Journal of the Acoustical Society of America, 1994 The biosonar emissions of a free-swimming dolphin were measured with respect to direction and timing while the animal searched for and reported objects at various ranges and bearings from a test enclosure. The technology allows a quantitative description of the pulse-by-pulse scan pattern of the freely moving animal and subsequent inferences about ...

Intensity and directionality of bat echolocation signals
Frontiers in Physiology, 2013 The paper reviews current knowledge of intensity and directionality of bat echolocation signals. Recent studies have revealed that echolocating bats can be much louder than previously believed. Bats previously dubbed whispering can emit calls with source

Evolution: How Bat Biosonar Bests Prey Camouflage [PDF]
Current Biology, 2019 The detection of silent, motionless prey sitting directly on leaves has long been considered a task impossible to solve with echolocation alone. Now, a new study has identified a strategy that lets bats do just that - with the help of the leaf.

Acoustics in water: synergies with marine biology
EPJ Web of Conferences, 2017 This paper presents some of the bioacoustics related analysis that was performed on the ANTARES data, focussing on the year 2014. The data was processed for sperm whale, dolphin and shipping presence and grouped by hour of the day.

Modelo computacional sensorio-motor basado en el biosonar del Murciélago Tadarida Brasiliensis [PDF]
, 2017 Los murciélagos emiten chillidos ultrasónicos que rebotan en los objetos y posteriormente son interpretados por su sistema auditivo. Este proceso, llamado ecolocación (o biosonar), les permite determinar con precisión la posición, el tamaño y otras ...

TIME-RESOLVED SPECTRUM KERNEL FOR BIOSONAR TARGET CLASSIFICATION
, 2008 We consider the problem of biosonar landmark classification as an example of random and non-stationary signal classification in which finding robust and structure independent features for classification is not trivial.

Delayed response and biosonar perception explain movement coordination in trawling bats.
PLoS Computational Biology, 2015 Animal coordinated movement interactions are commonly explained by assuming unspecified social forces of attraction, repulsion and alignment with parameters drawn from observed movement data.
