An Experimental Methodology for the Determination of the Viscoelastic Properties of the Vocal Fold at Human Phonation Frequencies

The vocal folds are subjected to some of the largest magnitudes and frequencies of deformation of any tissue in the human body during normal voice production. Vocal fold scarring creates a functional deficit in this highly specific tissue that compromises the integrity of an individual’s voice. Scarring is the leading cause of dysphonia which often leads to a decreased quality of life, especially to those whose voice is an integral part of their profession.
