How sound is produced by human beings?
Asked by bbandab | 04 Feb, 2020, 09:10: PM
Expert Answer
In humans, the sound is produced by the voice box or the larynx.
The voice box is at the upper end of the windpipe.
When we speak, the two vocal cords in the larynx vibrate and produce sound.
These vocal cords are stretched across the voice box or larynx so that there is a narrow slit between them for the passage of air.
The vocal cords are about 20 mm long in men, 15 mm long in women (5 mm shorter) and they are very short in children.
