Abstract
The hearing of marine mammals has been extensively studied in the last decades and has focused primarily on species available in captivity such as the bottlenose dolphin Tursiops truncatus. Recent work has shown that mass stranding events could be related to anthropogenic sound exposure such as naval sonar activities, seismic surveys, or oil drilling exploration. Although little is known about the hearing abilities of most odontocete species, it is primordial to be able to obtain a rapid hearing assessment of stranded animals. A portable system was designed to be easily transported and used during stranding events, at rehabilitation facilities, and in laboratory settings. This overview provides a description of this system as well as an overview of the data collected so far.
