A Portable System for the Evaluation of the Auditory Capabilities of Marine Mammals

Abstract: We have created a portable system that is capable of measuring the hearing thresholds of marine mammals. It was designed for the purpose of testing the auditory capabilities for a wide range of marine mammal individuals and species. This system consists of multiple individual components, independently purchased or assembled. The major component of the system is a standard laptop computer with custom software that is able to both generate outgoing signals and acquire the corresponding brain potential measurements in response to those outgoing signals. The system has been, and still is, in an ongoing state of improvement and optimization with the goal of having a final system that could be used in nearly all field conditions.
