A white noise machine is a device that produces a sound that is random in character, which sounds like a rushing waterfall or wind blowing through trees. Often such devices do not produce actual white noise, which has a harsh sound, but more often pink noise, whose power rolls off at higher frequencies, or other colors of noise.
Famous quotes containing the words white, noise and/or machine:
“Let us then suppose the Mind to be, as we say, white Paper, void of all Characters, without any Ideas; How comes it to be furnished...? To this I answer, in one word, From Experience: In that, all our Knowledge is founded; and from that it ultimately derives it self.”
—John Locke (1632–1704)
“While we were thus engaged in the twilight, we heard faintly, from far down the stream, what sounded like two strokes of a woodchopper’s axe, echoing dully through the grim solitude.... When we told Joe of this, he exclaimed, “By George, I’ll bet that was a moose! They make a noise like that.” These sounds affected us strangely, and by their very resemblance to a familiar one, where they probably had so different an origin, enhanced the impression of solitude and wildness.”
—Henry David Thoreau (1817–1862)
“But it is found that the machine unmans the user. What he gains in making cloth, he loses in general power. There should be a temperance in making cloth, as well as in eating.”
—Ralph Waldo Emerson (1803–1882)
