Název v původním jazyce

Face vibration measurement in singing – pilot study

Popis výsledku v původním jazyce

This study documents the possibility of using laser interferometry (ESPI) to monitor face surface oscillation based on measurements on onesubject (M, 41 y. o.). The measurement was performed in three states of mutual position of the first formant and fundamental frequency. Synchronous measurements of facial vibrations employing an accelerometer confirmed the dominance of the harmonic component closest to the position of the first formant in the entire area of the head and neck. In addition to the amplitude ratios of facial surface oscillations, ESPI also distinguished the phase differences. Standing waves dominate in the oscillations of the face. The area around the corners of the mouth always oscillated most strongly and coincided with the oscillation of the upper forehead and neck. The areas around the eyes, chin, and ear vibrated in antiphase. Above the lower jaws, there was a running wave that progressed from the chin towards the angle of the mandible.
