Auditory sensitivity of the harbour porpoise Phocoena phocoena
Andersen, S.
Investigations on Cetacea (1970)
An audiogram has been obtained from the harbour porpoise, Ph.phocoena, in water from 1 to 150 kHz by using the operant conditioning technique. The highest sensitivity was measured between 8…
Directional hearing in the harbour porpoise Phocoena phocoena
Andersen, S.
Investigations on Cetacea (1970)
The forced choice variation of the method of constant stimuli was used to study the ability of angular discrimination at 2 kHz of a harbour porpoise Phocoena phocoena. A minimum…
