The purpose of this study was to (a) determine the conditions needed to elicit phonation from excised human larynges and the resultant range of phonations produced, (b) compare that with similar information previously obtained from canine, pig, sheep and cow and (c) relate those findings to previously reported information about viscoelastic properties of the vocal fold tissue (i.e. stress strain curves and Young’s Modulus). Six human larynges of the geriatric group (age ranges 70–89) were mounted on the bench without supraglottic structures and phonation was achieved with the flow of heated and humidified air through the tracheal tube. Using various sutures to mimic the function of the laryngeal muscles, the larynges were put through a series of sustained oscillations with adduction as a control parameter. The human larynges oscillated with an average frequency that was close to the canine larynges, but the oscillation behavior and wide frequency range were similar to those of pig larynges. The similarity of the wide vibration frequency ranges of human and pig larynges may be due to the nonlinear behavior of their elasticity, which is related to their vocal folds high collagen content. On the contrary, other species with limited frequency ranges showed almost linear stress-strain curves due to the higher elastin and lower collagen contents. The physiological differences in the linearity and ranges of oscillation of excised larynges reported in this study and previous studies are reflective of the tissue composition and mechanics.
