Comparison of Acceleration and Impact Stress as Possible Loading Factors in Phonation: A Computer Modeling Study

Original language description

Impact stress is suspected to be the main traumatizing mechanism in voice production. However, the repetitive acceleration and deceleration may also traumatize the vocal fold tissues. Using an aeroelastic model of voice production, the study quantifies the acceleration and impact stress in relation to lung pressure, fundamental frequency (F0) and prephonatory glottal half-width. Both impact stress and acceleration were found to increase with lung pressure. Compared to impact stress, acceleration was less dependent on prephonatory glottal width and, thus, on voice production type. Maximum acceleration values were about 5-10 times greater for high F0 (approx. 400 Hz) compared to low F0 (approx. 100 Hz), whereas maximum impact stress remained nearly unchanged. Thus, the inertia forces present at high F0 a greater load for the vocal folds, and in addition to the collision forces contribute to the fact that females have vocal fold traumas more frequently than males.
