Explanation:

Sound is produced when aerodynamic phenomena cause vocal folds to vibrate rapidly in a sequence of vibratory cycles with a speed of about:

110 cycles per second or Hz (men) = lower pitch

180 to 220 cycles per second (women) = medium pitch

300 cycles per second (children) = higher pitchhigher voice: increase in frequency of vocal fold vibrationlouder voice: increase in amplitude of vocal fold vibration

Vibratory Cycle = Open + Close Phase

The vocal fold vibratory cycle has phases that include an orderly sequence of opening and closing the top and bottom of the vocal folds, letting short puffs of air through at high speed. Air pressure is converted into sound waves.

Not Like a Guitar String

Vocal folds vibrate when excited by aerodynamic phenomena; they are not plucked like a guitar string. Air pressure from the lungs controls the open phase. The passing air column creates a trailing “Bernoulli effect,” which controls the close phase.

The Process of Voice

Voice production involves a three-step process.

A column of air pressure is moved towards the vocal folds

Air is moved out of the lungs and towards the vocal folds by coordinated action of the diaphragm, abdominal muscles, chest muscles, and rib cage

Vocal fold vibration – sequence of vibratory cycles:

Vocal folds are moved to midline by voice box muscles, nerves, and cartilages

The vibratory cycle occurs repeatedly; one vibratory cycle is as follows:

Column of air pressure opens bottom of vocal folds

Column of air continues to move upwards, now towards the top of vocal folds, and opens the top

The low pressure created behind the fast-moving air column produces a “Bernoulli effect” which causes the bottom to close, followed by the top

Closure of the vocal folds cuts off the air column and releases a pulse of air

New cycle repeats

The rapid pulses of air created by repeat vibratory cycles produce “voiced sound” which is really just a buzzy sound, which is then amplified and modified by the vocal tract resonators, producing voice “as we know it.” (See table below)

Loudness: Increase in air flow “blows” vocal folds wider apart, which stay apart longer during a vibratory cycle – thus increasing amplitude of the sound pressure wave

Pitch: Increase in frequency of vocal fold vibration raises pitch

Answer:

The trombone player produces sound at the mouthpiece of the instrument with his lips vibrating from air that passes from the mouth.
