What is the Voicebox Doing When You Scream? Yodel?

In the same spirit of a recent TEDMED talk by Nate Bell and re-published on CNN Jan 12, 2012 whereby he performed various beatboxing noises while stroboscopy was performed, I decided to record a similar video with a person performing various unusual human vocalizations to see what happens.

For those who don't know what stroboscopy is, click here.

Such vocalizations recorded included various types of human screams and a yodel.

What is Vocal Cord Stroboscopy?

Stroboscopy of the vocal cords is a special exam whereby a scope is introduced down into the throat where the vocal cords can be directly visualized. Using a special light, the vibration of the vocal cords can be examined and allows identification of subtle pathology that can contribute to a raspy voice.

The exam is recorded and can be played back at any speed to allow for careful analysis.

Here is a YouTube video our office has made showing how this exam is performed!
