noise (n.)

c. 1200, "sound of a musical instrument;" mid-13c., "loud speech, outcry, clamor, shouting;" c. 1300, "a sound of any kind from any source," especially a loud and disagreeable sound, from Old French noise "din, disturbance, uproar, brawl" (11c., in modern French only in phrase chercher noise "to pick a quarrel"), also "rumor, report, news," a word of uncertain origin, replacing Replaced native gedyn (see din).

According to some, it is from Latin nausea "disgust, annoyance, discomfort," literally "seasickness" (see nausea). According to others, it is from Latin noxia "hurting, injury, damage." OED considers that "the sense of the word is against both suggestions," but nausea could have developed a sense in Vulgar Latin of "unpleasant situation, noise, quarrel" (compare Old Provençal nauza "noise, quarrel"). Confusion with annoy, noisome, and other similar words seems to have occurred.

From c. 1300 as "a disturbance; report, rumor, scandal." In Middle English sometimes also "a pleasant sound." In 16c.-17c. "a band or company of musicians." Noises off, as a stage instruction in theater, "sound effects, usually loud and confused, made off stage but to be heard by the audience as part of the play," is by 1908.

radio (n.)

"wireless transmission of voice signals with radio waves," 1907, abstracted or shortened from earlier combinations such as radio-receiver (1903), radiophone "instrument for the production of sound by radiant energy" (1881), radio-telegraphy "means of sending telegraph messages by radio rather than by wire" (1898), from radio- as a combining form of Latin radius "beam" (see radius). Use for "radio receiver" is attested by 1913; sense of "sound broadcasting as a medium" also is from 1913.

That winter, however—the winter of 1921-22—[radio] came with a rush. Soon everybody was talking, not about wireless telephony, but about radio. A San Francisco paper described the discovery that millions were making: "There is radio music in the air, every night, everywhere. Anybody can hear it at home on a receiving set, which any boy can put up in an hour." In February President Harding had an outfit installed in his study, and the Dixmoor Golf Club announced that it would install a "telephone" to enable golfers to hear church services. [Frederick Lewis Allen, "Only Yesterday: An Informal History of the 1920's," 1931]
It is not a dream, but a probability that the radio will demolish blocs, cut the strings of red tape, actuate the voice "back home," dismantle politics and entrench the nation's executive in a position of power unlike that within the grasp of any executive in the world's history. [The Reading Eagle, Reading, Pa., U.S.A., March 16, 1924]

As late as July 1921 the New York Times was calling it wireless telephony, and wireless remained widespread until World War II, when military preference for radio established it as the word. As an adjective by 1912, "by radio transmission;" meaning "controlled by radio" is from 1974. Radio _______ as the proper name of a particular radio station or service, "radio station or service from _______" is by 1920. A radio shack (1946) was a small outbuilding housing radio equipment.
