Edison’s early ‘tone tests’ were staged demonstrations rather than genuine proofs of fidelity
Evidence
Edison, in 1901, claimed that the phonograph had no “tone” of its own. To prove it, he created a traveling show in which his phonograph was demonstrated in “tone tests” that consisted of presentations with a live performer. Morton (2000) reports, “Edison carefully chose singers, usually women, who could imitate the sound of their recordings and only allowed musicians to use the limited group of instruments that recorded best for demonstrations” (p. 23). Of a 1916 demonstration in Carnegie Hall before a capacity audience of “musically cultured and musically critical” listeners, the New York Evening Mail reported that “the ear could not tell when it was listening to the phonograph alone, and when to actual voice and reproduction together. Only the eye could discover the truth by noting when the singer’s mouth was open or closed” (quoted in Harvith and Harvith, 1987, p. 12). — Toole, Floyd E, Sound reproduction- the acoustics and…, 382
