“…The basic paradigm that evaluates laryngeal hyperfunction is to look for compression of the supraglottic structures during phonation [29]. This supraglottic activity may be separated into two components: (1) A-P supraglottic activity and (2) medial supraglottic activity [30,31,32]. In the present study most of the participants from the experimental group not only demonstrated laryngeal supraglottic activity during singing, but 14 of them (67%) also presented with some slight degree of laryngeal supraglottic activity during speaking voice tasks.…”

Objective: The present study aimed to vocally assess a group of rock singers who use growl voice and reinforced falsetto. Method: A group of 21 rock singers and a control group of 18 pop singers were included. Singing and speaking voice was assessed through acoustic, perceptual, functional and laryngoscopic analysis. Results: No significant differences were observed between groups in most of the analyses. Acoustic and perceptual analysis of the experimental group demonstrated normality of speaking voice. Endoscopic evaluation showed that most rock singers presented during singing voice a high vertical laryngeal position, pharyngeal compression and laryngeal supraglottic compression. Supraglottic activity during speaking voice tasks was also observed. However, overall vocal fold integrity was demonstrated in most of the participants. Slightly abnormal observations were demonstrated in few of them. Singing voice handicap index revealed that the most affected variable was the physical sphere, followed by the social and emotional spheres. Conclusions: Although growl voice and reinforced falsetto represent laryngeal and pharyngeal hyperfunctional activity, they did not seem to contribute to the presence of any major vocal fold disorder in our subjects. Nevertheless, we cannot rule out the possibility that more evident vocal fold disorders could be found in singers who use these techniques more often and during a longer period of time.

“…More detailed information on dynamic characteristics of the other laryngeal structures, like, e.g., the ventricular folds, could also be helpful since these structures contribute to phonation in certain singing styles ͑Fuks et Södersten, 1999͒ or in patients with voice disorders ͑Kruse, 1981;von Doersten et al, 1992;Schutte et al, 1998;Š vec et al, 1997. For a more extensive analysis, however, it is desirable to employ automated or semi-automated image detection ͑Wittenberg, 1997͑Wittenberg, , 1998Saadah et al, 1998;Larsson et al, 1999͒ instead of manual analysis of the images which is exceedingly time consuming.…”

The study presents the first attempt to investigate resonance properties of the living vocal folds by means of laryngoscopy. Laryngeal vibrations were excited via a shaker placed on the neck of a male subject and observed by means of videostroboscopy and videokymography (VKG). When the vocal folds were tuned to the phonation frequency of 110 Hz and sinusoidal vibration with sweeping frequency (in the range 50-400 Hz) was delivered to the larynx, three clearly pronounced resonance peaks at frequencies around 110, 170, and 240 Hz were identified in the vocal fold tissues. Different modes of vibration of the vocal folds, observed as distinct lateral-medial oscillations with one, two, and three half-wavelengths along the glottal length, respectively, were associated with these resonance frequencies. At the external excitation frequencies below 100 Hz, vibrations of the ventricular folds, aryepiglottic folds and arytenoid cartilages were dominant in the larynx.

“…Their physical properties ͑high viscosity and low stiffness͒ are different from those of biomechanical oscillators such as the vocal folds ͑Haji et al, 1992͒. Yet, their vibration has been observed during specific vocal gestures: Asian throat singing ͑Fuks et Lindestad et al, 2001;Sakakibara et al, 2001, 2004͒, Mediterranean traditional polyphony ͑Henrich et al, 2006͒, rock singing ͑Zang-ger Borch et al, 2004͒, pathological phonation ͑Lindestad et al, 2004Nasri et al, 1996;Von Doersten et al, 1992͒. Several vibratory gestures can be distinguished: periodic or aperiodic, in phase or not with the vocal fold vibration, with or without ventricular contact. In this study, we focus on a particular type of ventricular fold vibratory movement, referred to as vocal-ventricular phonation mode by Fuks et al ͑1998͒.…”

Occurrences of period-doubling are found in human phonation, in particular for pathological and some singing phonations such as Sardinian A Tenore Bassu vocal performance. The combined vibration of the vocal folds and the ventricular folds has been observed during the production of such low pitch bass-type sound. The present study aims to characterize the physiological correlates of this acoustical production and to provide a better understanding of the physical interaction between ventricular fold vibration and vocal fold self-sustained oscillation. The vibratory properties of the vocal folds and the ventricular folds during phonation produced by a professional singer are analyzed by means of acoustical and electroglottographic signals and by synchronized glottal images obtained by high-speed cinematography. The periodic variation in glottal cycle duration and the effect of ventricular fold closing on glottal closing time are demonstrated. Using the detected glottal and ventricular areas, the aerodynamic behavior of the laryngeal system is simulated using a simplified physical modeling previously validated in vitro using a larynx replica. An estimate of the ventricular aperture extracted from the in vivo data allows a theoretical prediction of the glottal aperture. The in vivo measurements of the glottal aperture are then compared to the simulated estimations.
