Vocal Health Part 1: Producing Sound
Vocal Health and You Lesson 1: Producing Sound
EQ: How does the body produce sound?
The Voice
-
What Is Sound?
- Vibrations that travel through the air or another medium and can be heard when they reach a person’s or animal’s ear.
-
The voice is controlled by 2 factors:
- Air
- Vocal Folds, "cords" (Focus of lesson 1)
-
Vocal Folds
- Vocal folds require air and vibration to create sound. It is air pushing up out of our lungs that causes the folds to vibrate and create sound.
-
Vocal Fold Examples:
-
If you pluck a rubber band, the rubber band moving back and forth produces twanging sounds.
-
Sound travels when a string vibrates, it makes molecules of gases in the air next to it vibrate.
- The molecules squeeze together, then spread apart.
- A vibration that spreads away from a vibrating object is a sound wave.

-
Vocal folds stretch and relax to make high and low pitches, similar to guitar strings.
- The tighter the string, the tighter and more vibrations, more vibrations, which results in a higher pitch.
-
The more loose a string is the fewer vibrations, vibrations become longer, which results in a lower pitch.
