An infant Risso's dolphin (Grampus griseus) was rescued from the beach in Southern
Portugal, and an audiogram was measured using auditory evoked potentials (AEP) and …

Eight bottlenose dolphins Tursiops truncatus (four male, four female) were trained to
respond to 100-ms tones. Three male dolphins (ages 23, 26, and 34) exhibited hearing …

A fresh water Amazon River dolphin, Inia geoffrensis, was conditioned to respond to pure
tones by pushing a response lever. By using this method an audiogram was obtained for …

The hearing threshold of a bottle‐nosed dolphin from the Eastern Pacific was tested using
behavioral response techniques. The animal responded to signals ranging from 2 to 135 …

This is the first report of an underwater audiogram from a dolphin in a capture-and-release
scenario. Two bow-riding white-beaked dolphins Lagenorhynchus albirostris (a female and …

Devices known as jawphones have previously been used to measure interaural time and
intensity discrimination in dolphins. This study introduces their use for measuring hearing …

While odontocetes do not have an external pinna that guides sound to the middle ear, they
are considered to receive sound through specialized regions of the head and lower jaw. Yet …

In odontocetes, underwater audiograms have been obtained mostly in one or two
individuals in a species. A representative number of animals should be investigated to …

It is a widely accepted hypothesis that echolocating dolphins (Tursiops truncatus) best
receive returning acoustic signals over the panbones of the lower jaw. It is also widely …

The underwater hearing sensitivity of a striped dolphin was measured in a pool using
standard psycho-acoustic techniques. The go/no-go response paradigm and up–down …
