Question

Answer 1

The sound that Tina produces while singing is loud and high-pitched.

How is a sound produced?

Vibrations that travel through the air or another medium and can be heard by an observer are called sounds. Sound is produced by the following cycle:

• A column of air in the lungs leads to the opening of the bottom section of vocal folds. It then continues to move upwards towards the top of the vocal folds and escapes out.

• This causes Bernoulli's effect, that is as low pressure gets created behind the fast-moving air column, the bottom section of the vocal folds closes, followed by the top.

• The air gets cut off due to the closure of the vocal folds which releases a pulse of air and the cycle continues.

Therefore, when Tina sings larger vibrations are created, and the tension within her vocal cords increases producing a very high-pitched loud sound.
