Abstract
A thick membrane is approximated by a set of 16 masses, allowing for 32 degrees of freedom. The restoring forces are a combination of longitudinal tension and material elasticity. Thus the vibration becomes stringlike for high frequencies (high tension in the ligaments, or cord edges) and springlike for low frequencies (elastic properties of the vocalis muscle). Longitudinal tension and medial compression define the statics of the system of coupled masses, and the air flow determines the dynamics. Vibrato can be introduced by slowly modulating either the subglottal pressure or the cord length, i.e., the crico-thyroid muscular tension. Registration is accomplished by manipulating the elastic properties and the tension on the vocalis muscle. Various falsetto modes, including horizontal phasing along the edge of the cord, are set up by a medial compression adjustment. The set of coupled equations is programmed on a small computer which includes a graphic display.
