A singer’s formant near 3 kHz lets trained voices cut through orchestra sound

Evidence

This peak has similar characteristics to the formants in the vocal tract response, and for this reason it is known as the “singer’s formant.” The presence of energy in this peak enables the singer to be heard above an accompanying orchestra because it is a section of the frequency spectrum in which the singer’s output prevails. This is what gives the professional singing voice its characteristic “ring,” and it is believed to be the result of lowering the larynx and widening the pharynx (see Figure 4.32) which is adopted by trained Western operatic singers. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1380

Categorization

• DEFINE: Defines the singer’s formant as a spectral peak around 3 kHz produced by larynx lowering and pharynx widening.
• QUESTION: Could this mechanism be detected and reproduced electronically, or applied to audio engineering for voice-over-orchestra clarity?
