Have you ever wondered why our voices change as we grow older? Over the years, a human body undergoes a lot of changes. One of them is the depth of voice. There are two reasons as to why human voice changes over time: the age of vocal cords and the size of larynx. Larynx or the voice box is a part of the respiratory system that is used to breathe, talk, and swallow. It is a system of different muscles that supports and moves the vocal cords inside it. |
The age of a human’s vocal cords causes big changes. As a person ages, the vocal cords ages too. People experience the first major shift on their voices when starting to become an adult. That’s the time when our voices start to deepen. That is a sign that the vocal cords are aging. Most people’s voices stay almost the same for about 50 years after the start of becoming an adult. However, as people grow older, they experience signs relating to aging voice called presbyphonia.

Next is the size of the larynx. The voice is produced through the sound waves of the vocal cords. The bigger the vocal cords, the deeper the voice is. Men have bigger larynges than women. This is the reason why men’s voices are bigger and deeper than that of women’s. When larynges and vocal cords grow, they create bigger sound waves which makes their voices bigger and deeper as they age.

Please explain what you learned through this lecture. |
Through this short lecture, I learned that there are two reasons as to why our voices change as we grow older. The age of our vocal cords deepens our voices and it starts before becoming an adult. I also learned that the depth of the voice depends on the size of the larynx. This is the reason why men have deeper voices than women. |
