Higher closed quotient increases vocal efficiency through reduced lung sound leakage

Evidence

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.
