The Mechanics Of An Elephant's Voice

April Flowers for redOrbit.com - Your Universe Online African elephants are known to communicate with infrasound - extremely low-pitched vocalizations - over a distance of miles. These infrasounds are at a very low frequency rate, fewer than 20 Hertz per second, and are generally below the threshold of human hearing. A new study, published in the August 3 issue of Science, shows that elephants rely on the same mechanism that produces human speech, and the vocalizations of other mammals,...

When lions and tigers roar loudly and deeply — terrifying every creature within earshot — they are somewhat like human babies crying for attention, although their voices are much deeper. So says the senior author of a new study that shows lions' and tigers' loud, low-frequency roars are predetermined by physical properties of their vocal fold tissue — namely, the ability to stretch and shear — and not by nerve impulses from the brain. "Roaring is similar to what...

Discovery by George Washington University researchers may improve treatments From a baby's first blurted "bowl!'" for the word "ball" to the whispered goodbye of a beloved elder, the capacity for complex vocalizations is one of humankind's most remarkable attributes -- and perhaps one we take for granted most of our lives. Not so for people who are afflicted with paralysis to their vocal folds and who suffer the social stigma of affected speech. Nor so for engineering professor Michael...

Work aimed at fighting voice disorders to be presented at Fluid Dynamics Conference in Minneapolis, Nov. 22-24, 2009 When people speak, sing, or shout, they produce sound by pushing air over their vocal folds -- bits of muscle and tissue that manipulate the air flow and vibrate within it. When someone has polyps or some other problem with their vocal folds, the airflow can be altered, affecting the sound production. "Voice disorders affect 30 percent of the general population and up to 60...
