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…
Effect of two levels of masking noise on the hearing threshold of a harbor porpoise (Phocoena phocoena) for a 4.0 kHz signal
Kastelein, Ronald A.; Wensveen, Paul J.
Aquatic Mammals (2008)
The 50% detection hearing thresholds of a harbor porpoise for a 4.0 kHz narrow-band FM signal, presented at the background noise level in a pool and with two masking noise…
Harbor porpoise clicks do not have conditionally minimum time bandwidth product
Beedholm, Kristian
The Journal of the Acoustical Society of America (2008)
The hypothesis that odontocete clicks have minimal time frequency product given their delay and center frequency values is tested by using an in-phase averaged porpoise click compared with a pure…
Perception of low-frequency acoustic signals by a harbour porpoise (Phocoena phocoena) in the presence of simulated offshore wind turbine noise
Lucke, Klaus; Lepper, Paul A.; Hoeve, Bert; Everaarts, Eligius; van Elk, Niels; Siebert, Ursula
Aquatic Mammals (2007)
Using auditory evoked potential (AEP) methods, a study was conducted on a harbour porpoise (Phocoena phocoena) at the Dolfinarium Harderwijk in The Netherlands. The study measured the audible range of…
Responses of cetaceans to anthropogenic noise
Nowacek, Douglas P.; Thorne, Lesley H.; Johnston, David W.; Tyack, Peter L.
Mammal Review (2007)
1. Since the last thorough review of the effects of anthropogenic noise on cetaceans in 1995, a substantial number of research reports has been published and our ability to document…
Automatic Gain Control in Harbor Porpoises (Phocoena phocoena)? Central Versus Peripheral Mechanisms
Beedholm, Kristian; Miller, Lee A.
Aquatic Mammals (2007)
A previous study indicated no automatic gain control (AGC) in the auditory system of a harbor porpoise (Phocoena phocoena) as revealed by recording auditory evoked potentials to simulated echoes (Beedholm…
Differences in the response of a striped dolphin (Stenella coeruleoalba) and a harbour porpoise (Phocoena phocoena) to an acoustic alarm
Kastelein, R.A.; Jennings, N.; Verboom, W.C.; de Haan, D.; Schooneman, N.M.
Marine Environmental Research (2006)
Small cetacean bycatch in gillnet fisheries may be reduced by deterring odontocetes from nets acoustically. However, different odontocete species may respond differently to acoustic signals from alarms. Therefore, in this…
Harbour Porpoises on Horns Reef – Effects of the Horns Reef Wind Farm (Final Report)
Tougaard, Jakob; Carstensen, Jacob; Wisz, Mary S.; Jespersen, Martin; Teilmann, Jonas; Ilsted Bech, Nikolaj; Skov, Henrik
NERI Technical Report to Vattenfall A/S (2006)
The monitoring program on harbour porpoises at Horns Rev Offshore Wind Farm in the Danish North Sea, initiated in 1999, has now come to an end with collection of final…
Auditory brainstem response in a harbor porpoise show lack of automatic gain control for simulated echoes
Beedholm, Kristian; Miller, Lee A.; Blanchet, Marie-Anne
The Journal of the Acoustical Society of America (2006)
The auditory brainstem response (ABR) response to simulated echolocation clicks was studied in a harbor porpoise, Phocoena phocoena, to determine the relationship between the animal’s perceived echo strength and the…
Receiving beam patterns in the horizontal plane of a harbor porpoise (Phocoena phocoena)
Kastelein, Ronald A.; Janssen, Mirjam; Verboom, Willem C.; de Haan, Dick
The Journal of the Acoustical Society of America (2005)
Receiving beam patterns of a harbor porpoise were measured in the horizontal plane, using narrow-band frequency modulated signals with center frequencies of 16, 64, and 100kHz. Total signal duration was…
