What are vocal cords, and how do they produce sound? - #14741
I’ve always wondered how we produce sound when we speak or sing, and I recently learned that vocal cords play a big role. I don’t fully understand how they work or what causes problems when they’re damaged. What exactly are the vocal cords, and how do they produce sound? I read that they vibrate when air passes through them, but how does the tension and length of the vocal cords affect pitch and volume? Also, why do some people develop vocal cord issues, like hoarseness or loss of voice—can it be caused by overuse, illness, or stress? I also want to know how to take care of the vocal cords. Are there foods, habits, or exercises that can strengthen them, or are there risks that can damage them, like smoking or poor vocal habits? If anyone has had vocal cord issues, what was the cause, and what treatments helped? Did you need therapy, rest, or other forms of medical intervention to recover?
