Testing the acoustic tolerance of harbour porpoise hearing for impulsive sounds
journal contribution
posted on 2008-11-03, 11:15 authored by Klaus Lucke, Paul LepperPaul Lepper, Marie-Anne Blanchet, Ursula SiebertThe planned construction of offshore wind turbines in the North and Baltic Seas involves the emission of high numbers of intense
impulsive sounds when turbine foundations are driven into the ground
by pile driving. Based on knowledge about other odontocete cetaceans
(Finneran et al. 2002), it can be assumed that the source levels, which
will on average exceed 225 dB re 1 μPa at 1 m, bear a risk at least
for temporary threshold shift (TTS) in the auditory system of harbour
porpoises Phocoena phocoena that inhabit these waters. In order to
base the definition of noise-exposure criteria on information on the
acoustic tolerance of this species to single impulses, an auditory study
was conducted.
