Word Origin & History

"noise," c.1280, soun, from O.Fr. son, from L. sonus "sound," from PIE *swonos, from base *swen- "to sound" (cf. Skt. svanati "it sounds," svanah "sound, tone;" L. sonare "to sound;" O.Ir. senim "the playing of an instrument;" O.E. geswin "music, song," swinsian "to sing;" O.N. svanr, O.E. swan "swan,"
prop. "the sounding bird"). The final -d was established c.1350-1550 as part of a tendency to add -d- after -n-. The verb is attested from c.1300, from L. sonare, from sonus. First record of sound barrier is from 1939. Soundtrack is from 1929; sound check is from 1977; sound effects is 1909, originally live accompaniments to silent films.
"The experts of Victor ... will ... arrange for the synchronized orchestration and sound effects for this picture, in which airplane battles will have an important part." ["Exhibitor's Herald & Moving Picture World," April 28, 1928]

"uninjured," O.E. gesund "sound, safe, healthy," from P.Gmc. *sundas, from root '*swen-to- (cf. O.S. gisund, O.Fris. sund, Du. gezond, O.H.G. gisunt, Ger. gesund "healthy," source of the post-sneezing interjection gesundheit; also O.E. swið "strong," Goth.
swinþs "strong," Ger. geschwind "fast, quick"), with connections in Indo-Iranian and Balto-Slavic. Meaning "financially solid or safe" is attested from 1601; of sleep, "undisturbed," from 1548. Sense of "holding accepted opinions" is from 1526. Soundly "completely" is attested from 1577.

"fathom, probe," 1336 (implied in sounding), from O.Fr. sonder, from sonde "sounding line," probably from a Gmc. source (cf. O.E. sund "water, sea;" see sound (n.2)).

"narrow channel of water," c.1300, from O.N. sund "a strait, swimming," cognate with O.E. sund "power of swimming, water, sea," both from P.Gmc. *swumto-, from base *swem- (see swim (v.)).

sound 1   (sound)  Pronunciation Key 
  1. A type of longitudinal wave that originates as the vibration of a medium (such as a person's vocal cords or a guitar string) and travels through gases, liquids, and elastic solids as variations of pressure and density. The loudness of a sound perceived by the ear depends on the amplitude of the sound wave and is measured in decibels, while its pitch depends on its frequency, measured in hertz.

  2. The sensation produced in the organs of hearing by waves of this type. See Note at ultrasound.

sound 2   (sound)  Pronunciation Key 
  1. A long, wide inlet of the ocean, often parallel to the coast. Long Island Sound, between Long Island and the coast of New England, is an example.
