Frequency of greatest temporary hearing threshold shift in harbor porpoises (Phocoena phocoena) depends on the noise level.

2014

Journal of the Acoustical Society of America

Kastelein, R.A., Schop, J., Gransier, R., and Hoek, L.

Harbor porpoises may suffer hearing loss when they are exposed to high level sounds. After exposure for 60 min to a 6.5 kHz continuous tone at...
