Q. Why do women have a shriller voice compared to that of men?
Ans. We produce sounds due to the vibrations produced in the vocal cords that are situated within the larynx. When we speak, the air is pumped into the larynx, which causes the vocal cords to vibrate, producing sounds. Now, the pitch or shrillness of a sound depends on the frequency of vibrations of the vocal cord. Women have shorter vocal cords which vibrate more quickly and produce a higher pitch, while in men the longer vocal cords vibrate with low frequencies giving them deeper voice. Thus, women have high-pitched or shriller voice as compared to men.
