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

A thousand trills and quivering sounds
In airy circles o'er us fly,
Till, wafted by a gentle breeze,
They faint and languish by degrees,
And at a distance die.

Joseph Addison, An Ode for St. Cecilia's Day, VI.

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.

Sound

The murmur that springs
From the growing of grass.

Edgar Allen Poe, Al Aaraaf, Part II, line 124.
