Question 3 transcript:
"Recent discoveries are coming from all fields. From behavior, from work like mine, which is mostly modeling and anatomy, and from direct measurement just like we test humans and babies, we can ask the same questions. The most recent discoveries are how very wide the hearing range is across most whales and dolphins. For about twenty years we've known that dolphins can hear ten to twelve octaves. We hear eight octaves. An octave is a doubling of frequency, for instance, 300 Hz to 600 Hz is an octave. These animals hear from around 100 cycles per second up to almost 200,000 cycles per second and that is about ten octaves. We didn't know until very recently, looking at the ears for instance, that that is probably also true of the great whales, or the baleen whales."
