Voice+Box


 * Voice Box**

- The Larynx, commonly called the Voice Box , is an organ found in our neck. It involves breathing, __sound production__ ,protecting the trachea against food aspiration. __It manipulates pitch and volume__. The larynx houses the vocal folds (commonly but improperly termed the "vocal cords").

Sound is generated in the larynx, and that is where pitch and volume are manipulated.
 * How Larynx relates to sound** :

The larynx is a critical organ of human speech and singing. Without it we cannot produce voice or sound. It is also called the "Vibrator", our larynx is composed of two vocal folds that open during breathing and close during swallowing and voice production. When we produce voice, the airstream passes between the two vocal folds that have come together. These folds are soft and are set into vibration by the passing airstream. They vibrate very fast – from 100 to 1000 times per second, depending on the pitch of the sound we make. Pitch is determined by the length and tension of the vocal folds, which are controlled by muscles in the larynx.
