The present study describes the development and testing of a tool for dolphin research. This tool was able to visualize the dolphin echolocation signals as well as function as an acoustically operated "touch screen." The system consisted of a matrix of hydrophones attached to a semitransparent screen, which was lowered in front of an underwater acrylic panel in a dolphin pool. When a dolphin aimed its sonar beam at the screen, the hydrophones measured the received sound pressure levels. These…

Design and Benchmark Tests of a Multi-Channel Hydrophone Array System for Dolphin Echolocation Recordings

The design and application considerations of a computer based measurement system enabling 1 MS/s simultaneous sampling of 47 hydrophones for cross sectional recordings of echolocation beams of toothed whales (Odontocetes) are described.

Validation of a vibroacoustic finite element model using bottlenose dolphin simulations: the dolphin biosonar beam is focused in stages

Psychoacoustic laboratory studies with live dolphins require considerable resources and are essential for assessing the validity of our models. Computerized numerical modelling methods are a

Responses of Human-Habituated Wild Atlantic Spotted Dolphins to Play Behaviors Using a Two-Way Human/Dolphin Interface

Underwater observations revealed that some of these dolphins engaged in play behavior using man-made and natural objects in the presence of humans, and allowed humans to interact with them during play.

Peer Reviewed Title: Responses of Human-Habituated Wild Atlantic Spotted Dolphins to Play Behaviors Using a Two- Way Human/Dolphin Interface

Dolphin age class, sex, and levels of synchronization with humans all contributed to the success and level of engagement during exposure sessions between humans and dolphins.

47-channel burst-mode recording hydrophone system enabling measurements of the dynamic echolocation behavior of free-swimming dolphins.

A 47-channel burst-mode recording hydrophone system that enables highly resolved full beamwidth measurements on multiple free-swimming dolphins during prolonged recording periods and facilitates a wide range of biosonar studies.

Full-duplex acoustic interaction system for cognitive experiments with cetaceans

Cetaceans show high cognitive abilities and strong social bonds. Acoustics is their primary modality to communicate and sense the environment. Research on their echolocation and vocalizations with

Acoustic gaze adjustments during active target selection in echolocating porpoises

It is demonstrated that at short target ranges porpoises narrow their depth of gaze dramatically by adjusting their output so as to focus on a single target, which suggests that echolocating porpoise switch from a deliberative mode of sensorimotor operation to a reactive mode when they are close to a target.

Sensory Perception in Cetaceans: Part I—Current Knowledge about Dolphin Senses As a Representative Species

It is shown that despite extensive knowledge on audition, aspects such as context relatedness, the social function of vocalizations or socio-sexual recognition, remain poorly understood, and areas for further lines of investigation are proposed.

Cortical neurons of bats respond best to echoes from nearest targets when listening to natural biosonar multi-echo streams

The presented data suggest that global cortical suppression might establish a cortical “default mode” that allows selectively focusing on close obstacle even without active attention from the animals.

A review of zoo-based cognitive research using touchscreen interfaces.

The history, implementation, and potential outcomes of touchscreen research in zoo settings are discussed, with a focus on zoo-based touchscreen research on public display.



Acoustic Touch Screen for Dolphins, First application of ELVIS - an Echo-Location Visualization and Interface System

Dolphin sonar has been extensively studied over several decades, and much of its basic characteristics are well known (Au 1993). However, most of these studies have been based on an experimental

Linking the sounds of dolphins to their locations and behavior using video and multichannel acoustic recordings.

A system developed by linking acoustic locations of the sounds of captive bottlenose dolphins with an overhead video image and the sounds can be identified to the vocalizing dolphin and linked to its concurrent behavior represents a significant advance for studying the function of vocalizations of marine animals in relation to their context.

Dolphin sonar detection and discrimination capabilities

Close examination of the dolphin sonar system will reveal that the dolphin acoustic hardware is fairly ordinary and not very special, but these animals still demonstrate very unusual and astonishing capabilities.

A beamforming video recorder consisting of a video camera at the center of a 16 hydrophone array that allows researchers to correlate the acoustic and physical behaviors of marine mammals during studies of social interactions.

Inter-modal learning task in bottlenosed dolphins (Tursiops truncatus): a preliminary study showed that social factors might influence learning strategies

We studied the dolphin’s capacity to perform a cognitive task when information arrives through two different sensory modalities (visual and auditory). Three female bottlenosed dolphins (Tursiops

Functional morphology and homology in the odontocete nasal complex: Implications for sound generation

Comparing and contrasting the morphologic patterns of nasal structures across species representing every extant odontocete superfamily reveals probable homologous relationships, which suggests that all toothed whales may be making their biosonar signals by a similar mechanism.

Stimulus control in the use of landmarks by pigeons in a touch-screen task.

Pigeons were tested in a search task on the surface of a monitor on which their responses were registered by a touch-sensitive device, and results showed that pecks of 2 pigeons were controlled almost solely by the landmark, peck of 3 were controlled primarily by the landmarks but the frame could distinguish the correct landmark.

Spontaneous pointing by bottlenose dolphins (Tursiops truncatus)

Abstract. Two bottlenose dolphins (Tursiops truncatus) participating in a symbolic communication project spontaneously developed behaviors that resembled pointing and gaze alternation. The dolphins'

Conversations with a chimpanzee in a computer-controlled environment.

The linguistic-type skills of a young chimpanzee acquired in a computer-controlled language-training situation are reviewed and it is interpreted in terms of how enriched environments can serve to bring forth novel communication skills in the chimpanzee, which is otherwise alinguistic.

Ultrasound in Lund – three world premieres

In the historical section of the monograph Ultrasound in Medical Diagnosis, printed in 1976, one can read that a substantial part of the early development of the ultrasound-echo method took place in
