Next, air flow is modified by a series of structures that constitute the vocal tract
. Finally, the modified flow is radiated through the lips and nostrils.
Regarding the vocal tract
symptoms monthly frequency analyzed daily, it was observed higher occurrence of voice symptoms in the period without the dynamic soundfield system use.

The calls were distinguished between one another by their "formants," a term that is usually applied to the vocal tract
resonance that makes one human voice sound different from another.
Some researchers regard hyoid shape in humans as an indicator of a vocal tract
designed for speaking.

"However, in a helium-enriched atmosphere the tuning of the vocal cord vibration and the resonance of the vocal tract
are altered as the gas causes an upward shift of the resonance frequencies," he said
Semi-occluded vocal tract
postures and their applications in the singing voice studio.
sapiens--possessed a short set of neck vertebrae, resulting in a vocal tract
with a restricted range of speech sounds, McCarthy and his coworkers argue.
For vowels such as /a/ and /ae/ in the pitch range of [G.sub.4] to [E.sub.5] (396-660 Hz), the second harmonic [2f.sub.o] is dominant due to its proximity to the first resonance of the vocal tract
. (Note: For this discussion, resonance frequencies of the vocal tract
will be equated with formant frequencies, even though measured formant frequencies are sometimes only approximations of resonance frequencies.)
The voice's resonant frequency through the vocal tract
can be picked up via desktop microphone headsets and measured, allowing employers to tell in real time when their workers' brains are being overtaxed and, if necessary, intervene to avert disaster.
Bozeman explains the anatomic and acoustic principles that are the basis for pedagogic directives such as "inhale through a smile" or "inhale as if smelling a rose." He also presents the "two-room metaphor," an image he devised to help singers achieve ideal resonator shapes in the vocal tract
. Bozeman devotes a chapter to explaining this perception.
