Abstract
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.
