Sound Reception in the Yangtze Finless Porpoise and Its Extension to a Biomimetic Receptor

Biomimetics, 2023
Sound reception was investigated in the Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) at its most sensitive frequency. The computed tomography scanning, sound speed, and density results were used to develop a three-dimensional ...

Clownfish triggers plasticity in the acoustic communication of the three-spot damselfish [PDF]

, 2023
peer reviewedThe concept of Acoustic Niche plasticity refers to the plasticity of acoustic resources allocation within a species. Few studies have focused on this adaptability in fish species. The relationship between anemones and clownfish is one of the

The energetic basis of acoustic communication [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2010
Animals produce a tremendous diversity of sounds for communication to perform life's basic functions, from courtship and parental care to defence and foraging. Explaining this diversity in sound production is important for understanding the ecology, evolution and behaviour of species.

Sound production and associated behavior of tagged fin whales (Balaenoptera physalus) in the Southern California Bight [PDF]

, 2011
Background: For marine animals, acoustic communication is critical for many life functions, yet individual calling behavior is poorly understood for most large whale species. These topics are important for understanding whale social behavior and can also

Ship Radiated Noise Recognition Using Resonance-Based Sparse Signal Decomposition

Shock and Vibration, 2017
Under the complex oceanic environment, robust and effective feature extraction is the key issue of ship radiated noise recognition. Since traditional feature extraction methods are susceptible to the inevitable environmental noise, the type of vessels ...

Underwater acoustic communication messaging time stamp applied to global time synchronization

, 2014
This paper presents a new approach to time stamp messages in underwater acoustic communication. Message time stamping is a widely used method for synchronizing two clocks over a cabled or wireless communication, by exchanging time information in ...

Repeated elicitation of the acoustic startle reflex leads to sensitisation in subsequent avoidance behaviour and induces fear conditioning [PDF]

, 2011
Background: Autonomous reflexes enable animals to respond quickly to potential threats, prevent injury and mediate fight or flight responses. Intense acoustic stimuli with sudden onsets elicit a startle reflex while stimuli of similar intensity but with ...

Underwater TDOA Acoustical Location Based on Majorization-Minimization Optimization

Sensors, 2020
Underwater acoustic localization is a useful technique applied to any military and civilian applications. Among the range-based underwater acoustic localization methods, the time difference of arrival (TDOA) has received much attention because it is easy

Efficient Acoustic Communication Techniques for Nanobots [PDF]

Proceedings of the 7th International Conference on Body Area Networks, 2012
In this work we present the simulation of a swarm of nanobots that behave in a distributed fashion and communicate through vibrations, allowing a decentralized control to treat endogenous diseases of the brain. Each nanobot is able to recognize a cancer cell, eliminate it and announce through a communication based on acoustic signals the presence of ...
