Abstract
An upper limit on aerodynamic (pulmonary) power produced in shouting and singing is on the order of 1 W. The radiated acoustic power is less than 10% of this aerodynamic power, and in conversational speech can be as little as 0.1%. Major dissipative elements are the vocal folds, the lungs, the soft walls of the vocal tract, and turbulence in the airstream emerging from the glottis. Some analytical calculations and some computer simulation will focus on the distribution of losses along the vocal tract. In particular, difference between the singing mode and the speaking mode will be highlighted. Speculations will be made on the techniques by which a singer can optimize the system for maximum power output. [Work supported by NIH.]
