Anthropogenic underwater sound in the seas and oceans is increasing. Phocoena phocoena (harbor porpoise) is sensitive to underwater sound because of its very acute hearing, wide hearing frequency range, and high responsiveness to sounds. The detection of sounds by animals and the degree to which sounds have an effect on animals involve the ...

Click Structure in the Porpoise, Phocoena phocoena

Journal of Mammalogy, 1969
The phonation of Phocoena phocoena consists of low intensity, narrow-band clicks usually near 2 kilohertz, produced singly or in bursts at repetition-rates as great as about 1000 per second. the higher repetition-rates show as harmonic bands in spectral analysis when relatively narrow analyzing filters are used. Many clicks contain variable emphasis at
