Effect of Speaking Environment
Several studies in vocal loading show that the speaking environment does have a significant impact on vocal loading. Still, the exact details are debated. Most scientists agree on the effect of the following environmental properties:
- air humidity - dry air increases stress experienced in the vocal folds
- hydration - dehydration increases effects of stress inflicted on the vocal folds
- background noise - people tend to speak louder when background noise is present, even when it isn't necessary. Increasing speaking volume increases stress inflicted on the vocal folds
- pitch - the "normal" speaking style has close to optimal pitch. Using a higher or lower pitch than normal will also increase stress in the speech organs.
In addition, smoking and other types of air pollution might have a negative effect on voice production organs.

“What has been the effect of [religious] coercion? To make one half the world fools, and the other half hypocrites. To support roguery and error all over the earth.”
—Thomas Jefferson (1743–1826)
“This is the great truth life has to teach us ... that gratification of our individual desires and expression of our personal preferences without consideration for their effect upon others brings in the end nothing but ruin and devastation.”
—Hortense Odlum (1892–?)
“People in places many of us never heard of, whose names we can’t pronounce or even spell, are speaking up for themselves. They speak in languages we once classified as “exotic” but whose mastery is now essential for our diplomats and businessmen. But what they say is very much the same the world over. They want a decent standard of living. They want human dignity and a voice in their own futures. They want their children to grow up strong and healthy and free.”
—Hubert H. Humphrey (1911–1978)
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
