A mechanical model of human vocal folds has been designed by researchers to show how asymmetrical airflow impacts normal and diseased vocal fold motion. These observations may lead to new devices ...

Finally, they will cultivate the cell-populated hydrogels in a bioreactor that simulates human phonation. “Overall, the combination of a tissue-mimetic hydrogel, primary human cells and a vibratory ...

“The cells that come from human vocal folds are uniquely suitable to be used for this purpose, but they're not that easy to obtain,” he said. So having them grown ahead of time would be an ...

Doctors built the vocal cords using cells from human donors. The cells were coaxed into forming tissue that mimics vocal fold mucosa – the flaps in the larynx that vibrate to create the sounds ...

Susan Thiebault, who has expertise in vocal fold physiology and biology at University of Wisconsin, Madison, also will contribute to the project. The model will include built-in airflow to stimulate ...

The vocal folds are a source of sound, whereas the pharynx, oral cavity, and nose function as a supraglottal resonating chamber, which is a primary component of the human vocal signature.

A dog’s voice box is pretty similar to a human’s, Welham said. So the researchers cut out one of the native canine vocal folds and glued a piece of the new bioengineered tissue in its place.

Another change that affects people’s vocal folds is aging. “Voice boxes begin to age in our late 40s. You can hear the changes as we get older,” Sivasankar said. “You have to use exercises to ...

From the outset of his second study, Herbst could already clearly see that the elephant's vocal folds were very different to ours. Comparing CT-scans of both the elephant's larynx and a human's ...
