Summary:
Researchers may have found the key to the intimidating and paralyzing affect that a tiger's roar has on animals, including humans. New research by bioacousticians shows that very low frequency sounds may be the key.

A tiger's intimidating roar has the power to paralyze the animal that hears it and that even includes experienced human trainers. Elizabeth von Muggenthaler, a bioacoustician from the Fauna Communications Research Institute in North Carolina, presented her research at the Acoustical Society of America meeting in Newport Beach, California on December 7. Bioacoustics is the study of the frequency or pitch, loudness, and duration of animal sounds to learn about an animal's behavior. At the meeting, von Muggenthaler discussed her work analyzing the frequency of tiger sounds to better understand the part of a tiger's roar that we can feel, but can't hear.
