Singer Can Hear Voice as Audience Hears It, 1934

So that would-be singers may hear themselves as others hear them, a Los Angeles voice teacher and former grand opera singer has invented and patented a voice reflector, in 1934. Fitted around the pupil’s neck like a collar, as shown above, its convolutions carry a part of the singer’s tones back to her own ears.

According to the inventor, his device will enable singers or public speakers to detect and correct faults in tone, volume, and diction during a few hours’ practice, since they may hear in this way exactly how their voices in singing or speaking would sound to an audience.
