Production of Sound by Voice Box

The voice box, also known as the larynx, is a crucial organ responsible for producing sound in humans. It is located in the neck and plays a vital role in speech and vocalization. Here's how the voice box produces sound:

Vocal Cords

Within the voice box, there are two vocal cords that vibrate when air passes through them. These vibrations create sound waves, which are then shaped by the mouth, tongue, and lips to produce speech or singing.

Airflow

When we speak or sing, air from the lungs passes through the voice box and causes the vocal cords to come together. The controlled release of air through the vocal cords produces sound. The size and tension of the vocal cords determine the pitch and volume of the sound produced.

Regulation of Sound

The voice box also helps in regulating the pitch, loudness, and quality of the sound produced. Muscles in the larynx adjust the tension of the vocal cords to change the pitch, while the force of the airflow affects the loudness of the sound.

In conclusion, the primary function of the voice box or larynx in humans is to produce sound. It does so by vibrating the vocal cords with airflow from the lungs, allowing us to speak, sing, and communicate effectively.

Answer is a because The airstream provides the energy for the vocal folds in the voice box to produce sound...the vibrate very fast from 100 to1000 times per second,depending on the pitch of sound we make.Pitch is determined by the length and tension of the vocal folds,which are controlled by muscles in the larynx.
