Marine Mammal Hearing
There are several projects that fall under our investigation of marine mammal hearing diversity. They include (i) investigating the hearing range and sensitivity of previously untested species or populations and (ii) examining the diversity of cetacean auditory form and function.
Marine Mammals and Noise
I have investigated how noise impacts marine mammal hearing. This includes demonstrating sonar induces temporary hearing loss (temporary threshold shifts - TTS) and the relationship of sound duration and intensity short duration sound must be of very high amplitude to induce TTS).
Temporal Resolution in Marine Mammals
Localization of sounds is perhaps the most important function of hearing and identifying a sound's location is often aided by temporal cues. I am investigating how fast various species can receive and process short sounds and the comparative relationship between marine species. We've looked the temporal processing and its relationship to hearing and echolocation.
Cephalopod Auditory Temporal Resolution
We've been examining if and how squid can follow individual pulsed sounds and the maximum rate they can follow.
