Effects of Noise and Tonal Stimuli on Hearing in Pinnipeds

Abstract

The long-term goals of this effort are to assess the effects of tonal (sonar-like) and broadband noise on underwater and in-air hearing sensitivity of individuals of three species of pinniped: the California sea lion, harbor seal, and northern elephant seal. Specifically, the goals are to assess onset, growth, and recovery of noise-induced temporary threshold shift of hearing (TTS).
