THE FACE VIBRATION IN RESONANCE EXERCISES MEASURED BY THREE DIFFERENT METHODS - FIRST RESULTS

Popis výsledku v původním jazyce

Results of three vibration measurement methods (by accelerometers, vibrometers, optical measurement of the facial surface vibration by high speed camera) are presented. A subject (male, 37 y. o.) performed two vocal exercises (glissando and crescendo) inthree different types of vocal tract settings and three types of resonance tubes extending the vocal tract. In the case of glissandos peaks were found on the frequencies corresponding to the maximal vibration amplification of monitored areas (larynx, ala of nose, forehead). Results confirmed the effect of the vocal tract shape and the resonance tubes as for the frequency position of this maxima so for the maximal amount of the vibration amplification. The optical measurement showed position of the facial regions with the maximal vibration amplitudes. With resonance tubes attached to the area near the lips dominates, and in brumendos the maximal amplitudes were observed in the nose region.
