RADIO SINGER IN CELLOPHANE BELL (Dec, 1933)
RADIO SINGER IN CELLOPHANE BELL
To put the voice of a coloratura soprano on the air with fidelity, broadcasting engineers have devised a cellophane “bell” within which the singer stands. Covering her down to the waistline, the transparent envelop is said to do for the human voice what a mute does for a cornet or violin, and the singer can render her highest notes without fear of causing unpleasant vibrations in the microphone. The latter is placed outside the bell in the position shown in the photograph. By this novel expedient, a problem that has baffled broadcasters for years is believed to have been solved, and the results are expected to become apparent in the improved quality of the voices that radio listeners will hear in their home sets. It is expected that experiments will show other uses for the cellophane bell.
