Název v původním jazyce

The effect of resonance tubes on facial and laryngeal vibration - A case study

Popis výsledku v původním jazyce

The effects of resonant tubes of different lengths and diameters were measured by means of accelerometers placed on the subject’s larynx, forehead and cheek. The electroglottographic (EGG) and acousticalsignals were also recorded. The aim of the study was to find the frequency at which the resonance tubeshave maximal effect and to find, based on the analysis of the measured signals, the experimental method for the estimation of the resonance frequencies of the elongated vocal tract. The measured data were compared with transmission line modeling (TLM) and the yielding wall model (YWM). Our results show a better fit with the YWM modeled data than with TLM. The experimental data reveal two important kinds of measured maxima which can be identified as the maximum efficiency of the extended vocaltract (the maximum laryngeal vibration) and the correlation coefficient maximum (CCM) between laryn-geal vibration and the EGG signal, that we assume to be above the resonance frequency of the extendedvocal tract. The vibrational maximum frequency always lies below the CCM and their relative position does not differ by more than 25 Hz.
