Von Muggenthaler hopes to learn more about tigers, protect them from extinction, and understand the unheard, paralyzing power in their roar. Classic Inhale Snarl And Full Bodied Roar.

The next step for von Muggenthaler is to take the recorded infrasounds to scientists who can determine whether or not tigers can hear the infrasounds. It includes a huge variety of sounds from groans, growls, sniffs, roars and. Sometimes they would roar and leap towards the speakers and sometimes sneak away. When the researchers played back a tape of recorded tiger sounds including audible and infrasounds, the tigers appeared to react to these sounds. "Although untested, we suspect that this is caused by the low frequencies and loudness of the sound." "When a tiger roars-the sound will rattle and paralyze you," says von Muggenthaler. Bioacousticians found that tigers can create sounds at about 18 hertz and when tigers roar they can create frequencies significantly below this. In the first study of its kind, von Muggenthaler and her colleagues recorded every growl, hiss, chuff, and roar of twenty-four tigers at the Carnivore Preservation Trust in Pittsboro, North Carolina, and the Riverbanks Zoological Park in Columbia, South Carolina. Scientists believe that infrasound is the missing link in studying tiger communication. The lower the frequency, the farther the distance the sound can travel. "Humans can hear frequencies from 20 hertz to 20,000 hertz, but whales, elephants, rhinos, and tigers can produce sounds below 20 hertz." This low-pitched sound, called "infrasound," can travel long distances permeating buildings, cutting through dense forests, and even passing through mountains.
