The Greatest Force)

I wanted to start my analysis of the human voice by considering some of the physical aspects of it. Let us consider the case of speed and reach in the human body. If I were to ask what the fastest way for a man to propel something forward is, and to the greatest distance, you might think it would be by a kick, or a throw. Baseball pitchers can hurl a ball at 100 miles per hour, and cricket players have hurled a ball by hand 420 feet!

Let’s even suppose that we allow the person to use a simple tool, though no external source of power. Golfers have been known send a ball hundreds of yards, at speeds as high as 200 miles per hour!

But none of that would be the right answer. For the fastest, furthest cast, we do not look to the arms or the legs, we must look to the lungs. It is the human shout that is able to carry farther, and travel faster, than any other human-powered method. Under ideal conditions, some shouts have been reported to travel 10 miles, and the sound propagates at a speed of over 700 miles per hour. And what of the volume? When we shout, we physically vibrate the surrounding air particles in every direction, commanding the vibrations of over 100 billion cubic meters!

The human voice is therefore not only metaphorically powerful, but also physically magnificent as well. There is no other way that we can project farther, faster, and over a greater volume when using only the power of the body. But of course, this is not the only domain where the voice dominates. Tomorrow we will examine how being able to talk to one another and share ideas is the most important driver of all our technology and invention. I’ll see you then.
