- Influence of fatiguing noise on auditory evoked responses to stimuli of various levels in a beluga whale, Delphinapterus leucas
Summary: Investigation of the effects of a fatiguing sound on the hearing of a beluga whale within a wide range of levels of test signals shows that fatiguing noise exposure reduces responses to supra-threshold signals.
- Swimming and diving energetics in dolphins: a stroke-by-stroke analysis for predicting the cost of flight responses in wild odontocetes
Highlighted Article: Elevated locomotor costs during high-speed stroking by swimming dolphins demonstrate the energetic challenge of escape responses due to anthropogenic noise in the ocean.
- On doing two things at once: dolphin brain and nose coordinate sonar clicks, buzzes and emotional squeals with social sounds during fish capture
Summary: Dolphins use sonar to hunt fish; they make different sounds and different decisions simultaneously.
- Conditioned frequency-dependent hearing sensitivity reduction in the bottlenose dolphin (Tursiops truncatus)
Summary: Conditioned dolphin hearing dampening, caused by pairing warning and loud sounds, was found to differ with frequency of the warning stimulus, suggesting that the hearing dampening was not due to a simple stapedial reflex.
