how do human beings produce sound
The sound in human is produced by the voice box, that is also known as larynx. The voice box is at the upper end of the windpipe.There are 2 vocal cords,are stretched across the voice box in such a way that it leaves a narrow slit between them for the passage of air which produces sound.
Larynx moves when we swallow something. Inside the larynx, there are two vocal cords. There is a small gap between them. This small gap allows air to pass through. When we speak, air is forced into this small gap by the lungs. This prompts vocal cords to vibrate. Since vibrating objects produce sound, sound is produced due to the vibration of vocal cords.
Hope this helps!!!
