SOUND. Any thing audible; noise; that which is perceived by the ear. The experiments are numerous by which it has been found, that sound is audible to the distance of 50, 60, or 80 miles; but Dr. Hearne, physician to the king of Sweden, tells us, that at the bombardment of Holmia, in 1658, the sound was heard 30 Swedish miles, which make 180 of ours: and in the fight between England and Holland in 1672, the noise of the guns was heard even in Wales, which cannot be less than 200 miles.
The velocity of sound is 380 yards, or 1142 feet in a second of time, as found by very accurate experiment. The exactness of measuring distances by sound, has been sufficiently proved by measuring the same distances by trigonometry.
The medium velocity of sound is nearly at the rate of a mile, or 5280 feet in 4²⁄₃ seconds; or a league in 14 seconds; or 13 miles in one minute. But sea miles are to land miles nearly as 7 to 6: therefore sound moves over a sea mile in 5³⁄₄ seconds nearly; or a sea league in 16 seconds.
Sound flies 1142 feet in one second.
