Abstract:

Brain-wave activity was used to determine approximate auditory threshold levels for the unanesthetized bottlenosed porpoise Tursiops truncatus using a specially designed artifact inhibiting system. This technique can now be applied to rapidly within 4 to 6 hours estimate the hearing ability of T. truncatus over a frequency range of 5 kHz to 200 kHz to 200 kHz and could be employed to screen the hearing capabilities of other marine mammals. All equipment is portable and can be used in the field as well as in the laboratory. Author
