Auditory Masking Patterns in Bottlenose Dolphins from Anthropogenic and Natural Noise Sources.

摘要

The long-term goals of this project are to better understand and predict auditory masking in odontocetes with realistic, environmental noise types. Current predictions based on Gaussian noise masking will be improved upon. The objectives of this effort are to understand and predict how environmental noise (both anthropogenic and natural) affects detection, discrimination, and recognition abilities of odontocete cetaceans. The specific objectives for FY12 were to: Develop and test hypotheses to describe auditory masking patterns from FY10 and FY11; Develop predictive quantitative models to describe masking with environmental noise; Estimate auditory recognition thresholds with different noise types.
