Why does Your Child’s Voice Vary?
If you have a son at home, his voice is likely to get altered as he grows. Generally, as a young boy grows up, their voice develops significantly. Yet, for a very large period of time, the voices weren’t taken seriously; people still used to make fun of boys who had cracks in their voices, etc. However, a high pitched noise is generally made by boys undergoing puberty. However, as physical changes tend to become apparent in the boy’s body, the voice also tends to deepen significantly. The reason for this is the larynx, which is commonly referred to as the voice box. Because the muscles in the larynx aren’t as fully developed, the sound that comes from the larynx isn’t very deep. As the body undergoes the puberty phase, the larynx tends to become thicker and thicker. Even though this change occurs in both men and women, it is more evident in boys. A girl’s voice is likely to deepen by a couple of tones, while a boy’s voice deepens considerably. The mechanics of how the voice deepens are explained below:
How does squeaking occur?
Understanding the science behind squeaking is very important if you really wish to understand why your boy’s throat makes those squeaking sounds. It should be known that the larynx plays the primary role in the making of sound. It includes a couple of muscles (vocal cords) which are stretching along the larynx, similar to rubber bands. As a person opens their mouth to speak, air rushes from the lungs and straight in to the larynx, forcing these two muscles to vibrate, which ultimately results in a person making sound. Importantly, the pitch of a person’s voice is generally controlled by the amount of tightness with which contraction occurs in the vocal cord muscles at the time the air from the lungs hits them directly.
If you want to get a clearer illustration, just take up a rubber band, stretch it tightly and pluck on it. You will hear a high pitched ‘twang’ sound, which is similar to what happens in the throat of a human. Now, before a boy hits the age of puberty, his vocal cords aren’t all that big in size, and his larynx is also pretty small as well. That is the reason why his voice is generally quite high in pitch. However, as a boy goes through puberty, his larynx begins to get bigger, while the vocal cords also begin to get thicker and tend to expand significantly, hence making the voice sound deeper.
Similar to the larynx, growth is expected in the vocal cords of the person, and they also become significantly thicker. Moreover, the facial bones of a person also begin to grow, and as the cavities in the sinuses and the nose, etc. tend to increase, similar to the back of the throat of a person, they get even greater amounts of space in their faces which allow even greater amounts of sound to resonate smoothly.
