Question

Explain in brief how sound is produced by human beings

Answer 1

HEY BUDDY!
HERE IS YOUR ANSWER.

Sound is  produced by the vibrations of vocal cords. The vocal cords are attached to muscles which change the tension or stretching in the cords and the distance between the cords.

1)The muscle of vocal cords are completely relaxed due to which the vocal cords are separated and loose so that air from the lungs passes through them without producing any sound. When we are not talking or singing ,the two vocal cords are far apart with a lot of gap between them.

2)When we want to speak ,the muscles of vocal cords contract due to which the two vocal cords become stretched and close together leaving only a narrow slit between them. The lungs pass a current of air between the two vocal cords. This air makes the vocal cords vibrate. And the vibrating vocal cords produce sound.When we talk or sing we actually make our vocal cords vibrate. And vibration of vocal cords by expelled air produce vocal sounds.
