Larynx changing

When the body goes through during puberty, the larynx grows larger and thicker. This change occurs both boys and girls, but it is more evident for boys.

The girls voice change a few tons, so barely perceptible, while the boys voice change its significant effect.

The larynx is located in the neck and plays a major role in creating vocal sounds. Two muscles, also called vocal cords are stretched the larynx and are similar to rubber bands.

When a person speaks, air is released from the lungs and that leads to vibration of the vocal cords, which in turn produce speech sounds. Tone of voice or intensity is controlled by the degree of tension of the vocal cords when these are hit by the air coming from the lungs.

Before a boy reaches puberty, his larynx and vocal cords are small and thin. Therefore, the tone of voice is higher than that of an adult. During the puberty stage and after that the boy will have voice thicker, deeper due to the fact that larynx increases and vocal cords go through a process of thickening.

In addition, facial bones will grow. Cavities of the sinuses become enlarged, nose and throat area behind growing, creating more space in the face, leading to increased resonance space.

While the boy’s body adapts to these changes, certain tones of voice can be annoying. This process takes only a few months.

A normal stage of growth

The inflection of your child’s voice is only part of the normal stage of growth. While the boy gets used to these changes, it may have difficulty to control voice and it is possible to make an extra effort to keep sound under control.

Together with other obvious changes in physical appearance, you may notice a significant change in the neck. When the larynx grows, it is inclined at a different angle inside the neck, and part of it stands out from the front of the neck. This is Adam’s apple.

Period in which these changes occur varies from child to child, so that the voices of boys may start to change earlier, and the other guys a little later. Usually, the voice of a boy will change around the age of 11-14 years, even after a growth spurt.

In some cases, this change in voice can be gradually and in other cases a quick way. If your son is worried, stressed or embarrassed by the sound of his voice, explain that it is temporary and that everyone goes through this stage in some degree. After several months, he will likely have a resonant and thick voice, like an adult.
