“…Further, obtaining measurements of the impact stresses of a single vocal fold oscillating against a Plexiglas plate equipped with appropriate transducers 4 affords an opportunity to better understand vocal fold collisions, their role in normal phonation, and their potential as a cause of vocal fold nodules. 5,6 Concern arises as to the degree of similarity between the oscillation of a single vocal fold against a fixed structure and the symmetric oscillations of a normal pair of vocal folds. Considering the fact that some hemilaryngectomized patients achieve relatively normal phonation and the results of their experiments with nine excised canine larynges, Jiang and Titze 1 hypothesized a functional similarity of hemilaryngeal and laryngeal (normal) phonation.…”

An experimental study of the pressure distributions in an asymmetric larynx, hereafter referred to as a hemilarynx, was carried out at a glottal diameter of 0.04 cm and transglottal pressures of 3, 5, 10, 20, and 40 cm H(2)O. In each case, the glottal wall "on the left" was chosen to have an angle of 0 degrees with the midline, and the angle of the glottal wall "on the right" was varied through converging angles of 5 degrees, 10 degrees, and 20 degrees and diverging angles of 5 degrees, 10 degrees, and 20 degrees. The case of two parallel glottal walls, or the uniform glottis, was also examined. With the exception of the 20 degrees convergent case, the pressure distributions for most angles and pressures were bistable; that is, a stable flow situation persisted when the glottal exit flow jet was directed downstream either to the right or to the left in the rectangular "pharynx" tunnel. Bistability also occurred for the uniform glottis. Pressure differences arising from the different directions of the flow jet were often found to be small; however, differences for the diverging 10 degrees case were as large as 7% or 8%, and for the 20 degrees divergent case, 12%. Calculations with FLUENT, a computational package, gave excellent agreement with observed pressures. Implications of the pressure distribution data for the functional similarity of normal and hemilaryngeal phonation, hypothesized by Jiang and Titze, are discussed. In particular, the intraglottal pressures for converging and diverging angles for the hemilarynx were found to be quite similar to those of the full larynx with the same diameter and included angle or twice the diameter and twice the included angle, suggesting that the same mechanism of energy transfer operates in the two cases. Nondimensionalizing the pressure distributions with the transglottal pressures suggests that the shapes of the distributions at P=3, 5, 10, 20, and 40 cm H(2)O for a given geometry are similar. The pressure average of these dimensionless distributions may be interpreted as a template at that geometry, a description referred to as successful pressure scaling. When the entire data set is considered, variations from consistent pressure scaling averaged 1.4%, although these variations tend to be somewhat larger near the glottal entrance and for diverging angles of 10 degrees and 20 degrees. Some possible implications of the observed pressures for phonosurgery are discussed.

“…The internationally acclaimed English contralto Kathleen Ferrier was noted to have had a spacious pharyngeal cavity (Henderson, 1954) leading to the suggestion that capacious resonating chambers with a wide opening to the laryngeal vestibule were associated with a naturally good voice (Arnold, 1962;Sundberg, 1987;Sonninen et al, 1999). Titze (1998a) suggested that symmetry of the larynx, including symmetry of the vocal folds, could contribute to normal vocal fold vibration and better control of pitch, loudness and onset.…”

“…Titze (1998a) suggested that symmetry of the larynx, including symmetry of the vocal folds, could contribute to normal vocal fold vibration and better control of pitch, loudness and onset. Arnold (1962) suggested that a symmetrical, unobstructed, and easily viewable larynx were features contributing to a good singing voice. Conversely, an asymmetrical, constricted, and poorly accessible larynx would be found in individuals with an inferior singing voice.…”

“…Also, major recent changes in a per son's life situation are known to be relevant to functional dysphonia, at least in adults [7], In assessing the relevance and aetiology of child hoarseness, a distinction must be made between chronic and infectious, acute hoarse ness [8][9][10]. Chronic child hoarseness is often accompanied by vocal nodules [11][12][13][14] which are supposed to be manifestations of vocal abuse and hyperkinetic movements of phona tion [15,16], Arnold [ 15] identified three pre disposing, precipitating and aggravating causes of nodules: body type, hereditary con stitution of the mucous membrane and per sonality structure. Hoarseness has also been recognized to be a forerunner of mutational voice change [17], and mutational voice change has been found to occur as early as in 9-year-old children [ 18].…”

The parents of 55 10-year-old children answered questionnaires concerning 51 elements of potential relevance to voice function such as vocal habits, speech and language development, medical history, social history, physical environment and family relations. In addition, personality profiles of each child were assessed by its teacher and parents. The results were compared to an expert listening panel’s evaluation of hoarseness and vocal-fold status as determined by a visual examination by a phoniatrician. Eight boys were identified as being chronically hoarse. Gender, personality and hours spent per day in large groups were highly significant factors associated with hoarseness. A discriminant analysis based on the significant background variables correctly grouped 86.3% of the children.
