Trained singers keep vocal folds closed longer each cycle than untrained singers

Evidence

Experimental measurements on trained and untrained singers suggest that CQ is higher at all pitches for trained adult males and that it tends to increase with pitch for trained adult females in a patterned manner. Howard and colleagues suggest that the higher CQ provides the potential for a more efficient voice output by three means: (i) the time in each cycle during which there is an acoustic path via the open vocal folds to the lungs, where sound is essentially completely absorbed, is reduced, (ii) longer notes can be sustained, since less FIGURE 4. — David M.
