Question

What is the frequency of the sound produced when the vocal cords are:
(a) tight and thin ? (b) loose and thick?

Answer 1

(a) High pitch

(b) low pitch

Explanation:

Sound is produced when aerodynamic phenomena cause vocal folds to vibrate rapidly in a sequence of vibratory cycles.

If the vocal chord is tight and thin, it will produce a high frequency sound or you can say that it will produce high pitch sound as pitch of the sound directly depends on the frequency of the sound.

A thick and loose vocal chord will produce the sound of low frequency or low pitch.

Answer 2

Answer:

Muscles attached to the vocal cords can make the cords tight or loose.

(a) When the vocal cords are tight and thin, a sound of high frequency (high pitch sound) is produced.

(b) When the vocal cords are loose and thick, a sound of low frequency (low pitch sound) is produced.

Explanation:

Sound is produced when aerodynamic phenomena cause vocal folds to        vibrate rapidly in a sequence of vibratory cycles.
