Beatboxing Safer Than Singing
2013-12-23 13:54:18

Brett Smith for redOrbit.com - Your Universe Online The internet is full of people performing vocal gymnastics routines known as beatboxing – routines full of hash percussive sounds and larynx-straining squeals. According to a new study from researchers at the University of Illinois, beatboxing may actually be less harmful to the vocal cords than conventional singing. "While there are lots of data on how the voice is used and can be injured in singers, little is known about the...

Koalas Have A Unique Organ That Allows Mating Calls Similar To Elephants
2013-12-03 04:59:44

[ Watch the Video: Belching For The Ladies, Koala-Style ] April Flowers for redOrbit.com - Your Universe Online Koalas have the appearance of a living teddy bear, inviting many of us to assume they are cute and placid. When mating season starts, however, the males produce a bellow that defies their size and cuteness. As the males inhale, they make a sound somewhat like a creaky door, according to National Geographic reporter Ed Yong. Exhalations sound more like someone belching,...

Elephants And Humans Share Similar, Yet Distinct, Vocal Abilities
2013-10-17 12:13:06

Michael Harper for redOrbit.com - Your Universe Online Last year researchers from the University of Vienna settled a longstanding debate over the way elephants make sounds. With the natural passing of an African elephant in Berlin Tierpark Zoo in 2010, the researchers were able to recover the larynx and bring it into the lab for studying. In their paper released last year the researchers explained how similar an elephant's vocal system is to those used by humans. Lead researcher...

Reducing Voice Loss In The Elderly With Vocal Training
2013-06-25 05:32:08

redOrbit Staff & Wire Reports - Your Universe Online Researchers have successfully used vocal training to reduce some of the voice problems experienced by older rats and their work could ultimately lead to new treatment options for aging humans experiencing similar issues. University of Illinois speech and hearing science professor Aaron Johnson and colleagues from the University of Wisconsin explain that the aging process can cause the muscles of the larynx (the organ which...

A new made-in-the-lab material designed to rejuvenate the human voice, restoring the flexibility that vocal cords lose with age and disease, is emerging from a collaboration between scientists and physicians, a scientist heading the development team said here today. That's just one of several innovations that Robert Langer, Sc.D., discussed in delivering the latest Kavli Foundation Innovations in Chemistry Lecture at the 244th National Meeting & Exposition of the American Chemical...

The Mechanics Of An Elephant's Voice
2012-08-03 05:40:41

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,...

For treatment of vocal fold disorders, UD researchers look to insect protein A one-inch long grasshopper can leap a distance of about 20 inches. Cicadas can produce sound at about the same frequency as radio waves. Fleas measuring only millimeters can jump an astonishing 100 times their height in microseconds. How do they do it? They make use of a naturally occurring protein called resilin. Resilin is a protein in the composite structures found in the leg and wing joints, and sound...

Big Cat Roars Similar To Babies Crying
2011-11-03 05:10:16

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...

Larynx
2013-01-18 11:20:23

The larynx is an organ that is located within the throat, commonly referred to as the “voicebox”. While the larynx is the primary organ responsible for voice production, it is also crucial in breathing and protecting the airway structures. Location and Structure The larynx is a tube-shaped organ with an average length of four inches. It is located between the hypopharynx and the trachea. It is divided into three sections labeled supraglottis, glottis, and subglottis. The skeletal...
