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…
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…
Assessing auditory evoked potentials of wild harbor porpoises (Phocoena phocoena)
Ruser, Andreas; Dähne, Michael; van Neer, Abbo; Lucke, Klaus; Sundermeyer, Janne; Siebert, Ursula; Houser, Dorian S.; Finneran, James J.; Everaarts, Eligius; Meerbeek, Jolanda; Dietz, Rune; Sveegaard, Signe; Teilmann, Jonas
The Journal of the Acoustical Society of America (2016)
Testing the hearing abilities of marine mammals under water is a challenging task. Sample sizes are usually low, thus limiting the ability to generalize findings of susceptibility towards noise influences.…
Hearing pathways in the Yangtze finless porpoise, Neophocaena asiaeorientalis asiaeorientalis
Mooney, T. A.; Li, S.; Ketten, D. R.; Wang, K.; Wang, D.
Journal of Experimental Biology (2013)
How an animal receives sound may influence its use of sound. While ‘jaw hearing’ is well supported for odontocetes, work examining how sound is received across the head has been…
Pile driving playback sounds and temporary threshold shift in harbor porpoises (Phocoena phocoena): Effect of exposure duration
Kastelein, Ronald A.; Helder-Hoek, Lean; Covi, Jennifer; Gransier, Robin
The Journal of the Acoustical Society of America (2016)
High intensity underwater sounds may cause temporary hearing threshold shifts (TTSs) in harbor porpoises, the magnitude of which may depend on the exposure duration. After exposure to playbacks of pile…
A review of studies on attempts to reduce the entanglement of the Dall’s Porpoise, Phocoenoides dalli, in the Japanese salmon gillnet fishery
Hatakeyama, Y.; Ishii, K.; Akamatsu, T.; Soeda, H.; Shimamura, T.; Kojima, T.
Report of the International Whaling Commission (1994)
Dall's porpoises, Phocoenoides dalli, were often incidentally caught in the Japanese salmon gillnet fishery in the North Pacific. In order to investigate the reasons for entanglement, their auditory characteristics and…
Study of the cranial sinus nematode, Stenurus minor (Metastrongyloidea), in the harbour porpoise, Phocoena phocoena
Faulkner, J.
Master's Thesis - McGill University (1995)
Seventy-eight harbour porpoises, Phocoena phocoena, (33 females, 45 males) were obtained from the summer (June-September) cod fishery incidental-by-catch in the Gulf of St. Lawrence, and examined for the presence of…
Fort Richardson ordnance detonations and the harbor porpoise: A case study in marine mammal bioacoustics
Heenehan, H.
Honours Thesis - University of Conneticut (2009)
Hearing is extremely important for cetaceans because it is their “principal sense” (Weilgart, 2007) thus the harbor porpoise and other marine animals are highly dependent on sound for survival. This…
The modulation rate transfer function of a harbour porpoise (Phocoena phocoena)
Linnenschmidt, Meike; Wahlberg, Magnus; Damsgaard Hansen, Janni
Journal of Comparative Physiology A (2012)
During echolocation, toothed whales produce ultrasonic clicks at extremely rapid rates and listen for the returning echoes. The auditory brainstem response (ABR) duration was evaluated in terms of latency between…
How do odontocetes perceive their own sounds?
Behrmann, G.
European Research on Cetaceans (1988)
(...) The free-swinging bullae of odontocetes are very massive, their specific weight being twice that of the other skull bones. This feature led Yamada (1953) to his theory that the…
