Integrative Zoology, Volume 21, Issue 2, Page 331-342, March 2026.The audiogram of the world's first successfully captive‐born Yangtze finless porpoise was on average 40 dB higher than conspecifics. Congenital hearing disorders and noise exposure may be the primary cause of porpoise's hearing loss. ABSTRACT Aquariums globally have seen significant growth in recent decades.

Acoustic behaviour of Risso's dolphins, Grampus griseus, in the Canary Islands, Spain [PDF]
, 2013 The Risso's dolphin (Grampus griseus) is a poorly studied species, particularly with respect to its acoustic behaviour. The little we know about Risso's dolphin acoustics shows that they are an interesting case study given that they combine acoustic ...

Dynamics of biosonar systems in Horseshoe bats
, 2015 Horseshoe bats have an active ultrasonic sonar system that allows the animals to navigate and hunt prey in structure-rich natural environments. The physical components of this biosonar system contain an unusual dynamics that could play a key role in ...

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.

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 ...

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.

Interrelationships between intranarial pressure and biosonar clicks in bottlenose dolphins (Tursiops truncatus) [PDF]
, 2004 Recent advances in technology permitted the first simultaneous digital recording of intranarial pressure and on-axis acoustic data from bottlenose dolphins during a biosonar target recognition task. Analysis of pressurization events in the intranarial

BiomimeticsIn this paper, we introduce SonoNERFs, a novel approach that adapts Neural Radiance Fields (NeRFs) to model and understand the echolocation process in bats, focusing on the challenges posed by acoustic data interpretation without phase information ...

Frontiers in Physiology, 2013 Echolocating bats use the time elapsed from biosonar pulse emission to the arrival of echo (defined as echo-delay) to assess target-distance. Target-distance is represented in the brain by delay-tuned neurons that are classified as either heteroharmonic ...
