Standardization of Electrophysiological Measures of Hearing in Marine Mammals
The primary goal of this project is to develop the technology and methods required to make quantitative, repeatable, and interpretable measurements of pinniped hearing sensitivity using averaged evoked potentials recorded from the surface of the head. This effort will advance understanding of marine...

The primary goal of this project is to develop the technology and methods required to make quantitative, repeatable, and interpretable measurements of pinniped hearing sensitivity using averaged evoked potentials recorded from the surface of the head. This effort will advance understanding of marine mammal auditory physiology and provide the tools necessary for the study of population-level and species-level hearing so that noise impacts in marine ecosystems can be better understood. The immediate goals of this project are as follows: (1) transfer available technology from ongoing research with cetaceans to establish an appropriate system for recording auditory evoked potentials in pinnipeds, (2) develop protocols for electrode placement and stimulus presentation that result in optimal evoked potential recordings, (3) measure the hearing sensitivity of individuals from multiple pinniped species using evoked potential methodology, (4) benchmark the evoked potential measures of hearing against standard behavioral measurements obtained for the same individuals, and (5) compare both behavioral and physiological hearing measures obtained for pinnipeds with those obtained under similar conditions for dolphins.
