Sound
Similarly, a source of sound can have many different frequencies mixed. A musical tone's timbre is characterized by its harmonic spectrum. Sound in our environment that we refer to as noise includes many different frequencies. When a sound signal contains es, distributed equally over the audio spectrum, it is called white noise.

Famous quotes containing the word sound:
“The mastery of one’s phonemes may be compared to the violinist’s mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbor’s renderings indulgently, mentally rectifying the more glaring inaccuracies.”
—W.V. Quine (b. 1908)
“It’s precisely the disappointing stories, which have no proper ending and therefore no proper meaning, that sound true to life.”
—Max Frisch (1911–1991)
“When the sheep are in the fauld, and the kye at hame,
And a’ the warld to rest are gane,
The waes o’ my heart fa’ in showers frae my e’e,
While my gudeman lies sound by me.
Young Jamie lo’ed me weel, and sought me for his bride;”
—Lady Anne Lindsay (1750–1825)
