Developing an improved methodology for efficient and informative hearing assessment in marine mammals would prove insightful in expanding current knowledge regarding marine mammal hearing sensitivity, particularly in studying the effects of anthropogenic noise. This study examines the click-evoked auditory brainstem response in relation to upper frequency limit of hearing in the bottlenose dolphin (Tursiops truncatus) as a proxy for hearing capacity.
