There has been no study of the efficiency of any sound-producing system. Here there is a description of a device that records the force of each pull applied to a valve segment or strip of myocardium while the sound evoked is recorded. The relation of force to sound intensity, and the attenuation of sounds in air, blood, and ventricular and chest walls provide some quantitative data on a neglected phase of cardiac physiology.
