Sound
In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.
Sound
My eyes are dim with childish tears,
My heart is idly stirred,
For the same sound is in my ears
Which in those days I heard.
William Wordsworth, The Fountain.
Sound
Their rising all at once was as the sound
Of thunder heard remote.
John Milton, Paradise Lost (1667; 1674), Book II, line 476.
Sound
If a tree falls in a forest, and no-one is around to hear it, does it make a noise?
Source unknown, but apparently originating in the twentieth century; a 1910 physics book asks "When a tree falls in a lonely forest, and no animal is near by to hear it, does it make a sound? Why?" Charles Riborg Mann, George Ransom Twiss, Physics (1910), p. 235. See also: If a tree falls in a forest.
