10 Things You Didn’t Know About The Human Voice
Sound Is Generated In A Very Complex Way
Although many thought that the human voice was generated in a relatively simple way, research eventually showed that it is far more complex than initially believed. The sound is actually produced due to muscles in the throat contracting and relaxing, changing the resistance provided to air in the lungs, creating sound waves that can be further manipulated by the vocal cords.
The Oldest Recording Of The Human Voice Is From 1860
Édouard-Léon Scott de Martinville captured a voice on his invention, the phonautograph, in 1860. It traced the sound waves onto a turning cylinder. Researchers were recently able to play it back and hear the voice singing.
