从能量的基本概念开始，本文讨论了如何有效地将空气动力学能量转换为可听声音。衡量人的绩效效率是复杂的，可能包括身体和心理物理两个方面。声门效率的定义和计算的问题进行了讨论。它的结论是，人体是低效的，在生产的声音，需要计算的内在和外在的喉肌和呼吸肌的代谢功率，以定义一个更全球的声乐效率，成本/效益比必须确定评估之间的权衡，从音高和响度的增加，以及随之而来的组织损伤的效率增加。
Beginning with basic concepts of energy, this article addresses how efficient aerodynamic energy is converted to audible sound. Measurement of efficiency in human performance is complex and may include both physical and psychophysical dimensions. Problems with glottal efficiency definitions and calculations are discussed. It is concluded that the human body is inefficient in producing voice; that calculation of metabolic power for intrinsic and extrinsic laryngeal muscles and respiratory muscles are needed to define a more global vocal efficiency; and that cost/benefit ratios must be determined to assess trade-offs between the increases in efficiency derived from increases in pitch and loudness, and the consequent tissue damage.
