Abstract | Knowing the hearing sensitivities of marine mammals is fundamental to mitigating noise impacts. There are no direct hearing measures for any mysticete. Vocalization data suggest they have acute low and infrasonic (LF/IF) hearing and may be especially sensitive to anthropogenic sources. To address this issue, we analyzed the anatomy and material properties of dolphin, whale, and land mammal ears to determine whether mysticetes, like elephants, have ears specialized for IF/LF hearing. |
