“…It has been proposed that professional singers and opera choristers perform singing tasks that require rapid changes of subglottal pressure with intensive use of all the abdominal muscles leading to a collapse of the ribcage. They also regularly activate the diaphragm when there is a need for a rapid decrease in subglottal pressure, causing an abrupt and prolonged increase in intra-abdominal pressure and straining [31][32][33][34] . It has also been suggested that these mechanisms, repeated several times per day and over many years of professional singing activity, could increase the occurrence of reflux symptoms by disabling the diaphragmatic sphincters.…”

Background: An occupation-related susceptibility of professional singers to experience gastroesophageal reflux has been suggested. Aims: To investigate the prevalence of gastroesophageal reflux symptoms in a series of professional opera choristers, wind players, glassblowers and water polo players in comparison with a sample of general population. Subjects and Methods: A total of 202 professional opera choristers from well-known choirs in different Hungarian regions, 71 professional wind players, 43 glassblowers, 54 water polo players were identified and 115 control subjects were compared prospectively. Reflux symptoms together with selected individual characteristics and lifestyle habits were investigated in study groups through a reflux questionnaire. Results:Professional opera choristers reported a statistically significantly higher prevalence of heartburn, regurgitation and hoarseness than control subjects (p < 0.001). Among professional wind players, heartburn and regurgitation were significantly more frequent compared with controls (p < 0.05 and p < 0.01, respectively). Glassblowers reported a significantly higher prevalence of acid regurgitation in comparison with controls (p < 0.01). The prevalence of reflux symptoms in water polo players was similar to that of controls. In opera choristers, wind players and glassblowers, reflux symptoms appeared to be significantly correlated with the cumulative lifetime duration of professional singing, playing and working activity, respectively (p < 0.05). Conclusions: Our results demonstrate that professional opera choristers, professional wind players and glassblowers have a higher prevalence of reflux symptoms compared with control subjects. Gastroesophageal reflux in these professions should be considered as a work-related disorder that may have an impact on quality of life and may negatively interfere with professional performance.

“…On loogiline oletada, et faktori nr 3 mõju hääle spektrikomponentide tugevusbalansile on eriti suur nende kahe ülesande puhul, kus laulja pidi teadlikult muutma hääle dünaamikat (kuna hääle tugevust reguleeritakse peamiselt häälepaeltealuse rõhu abil). Vastav mõju võib esineda aga ka f-f ülesande täitmisel, sest lauljad kalduvad häälepealte alust õhurõhku suurendama hääle kõrgenedes ka siis, kui otseselt ei kavatsetagi laulda valjemini (Björkner 2008).…”

Hääle spektri mähiskõvera kuju stabiilsus varieeruva dünaamikaga heliredelite laulmisel

Teesid: Käesoleva töö eesmärk oli uurida, kas ja kuidas muutuvad klassikaliselt treenitud lauljate hääle tämbriga seotud akustilised parameetrid, kui laulda hääle dünaamikat ja helikõrgust muutes. Uurimust motiveeris läbi viima vokaalpedagoogilises kirjanduses sageli väljendatud seisukoht, et klassikalise laulutreeningu üks eesmärk on hääle kõlalise ühtluse saavutamine. Palusime kümnel meeslauljal (kelle hulgas olid ooperi-ja oratooriumisolistid ning laulueriala üliõpilased) laulda ühe oktavi ulatusega tõusvaid D-duuri gammasid (vahemikus d -d 1 ) kolmel moel: (1) kõige harjumuspärasema dünaamikaga, (2) häälevaljust kasvatades ja (3) häälevaljust kahandades. Salvestasime esitused väikese reverberatsiooniga helistuudios. Tarkvara Sopran 1.0.10 abil arvutasime iga lauldud noodi keskmise võimsusspektri, kus määrasime põhitooni ja lauljaformandi spektripiirkondade tugevused spektri kõige tugevama tipu taseme suhtes. Mõõtsime iga lauldud noodi puhul ka helirõhu taseme ja glotaalse aduktsiooni tugevust iseloomustavate sulguskvotsiendi ja kvaasikontaktkvotsiendi väärtused. Uuringutulemused näitasid, et vastavad parameetrid muutusid ülesannete täitmisel süstemaatiliselt kõigi lauljate puhul. Osa kirjeldatud muutustest tingisid puht-akustilised faktorid, mida vokalist ei saa vokaaltehnikaga mõjutada. Mõni laulja kasutas vokaaltehnilisi võtteid, mille eesmärgiks võis olla häälekõla tajutava ühtluse parandamine. Üks taolisi võtteid oli piano ja forte vahelise erinevuse tekitamine eelkõige hääle tämbri, mitte aga niivõrd otsese helirõhu taseme abil. Vastupidiseks strateegiaks oli just helirõhu taseme muutmine, samal ajal hääletämbri kanduvuse ja ereduse aspektiga seotud lauljaformandi suhtelise tugevuse varieerumist väiksena hoides. Hääle tajutav ühtlus võib olla seotud veel hääle mõningate omadustega, mida käesolevas töös lähemalt ei käsitletud. Hääleparameetrite väärtuste varieerumise viis sõltuvalt helikõrgusest ja dünaamikast võib oleneda ka häälikust, mida laulmisel kasutatakse ning helikõrguse piirkonnast.

“…They applied three kinds of methods: the comparison of a single professional singer in different musical styles 5,16,33,[39][40][41][42] ; the comparison of different groups specializing in one particular musical style 14,[43][44][45] ; or the examination of one melody performed by one group of participants with two different vocal techniques. [46][47][48] However, all these experimental designs have their limitations.…”

Effects of Melody and Technique on Acoustical and Musical Features of Western Operatic Singing Voices

Summary: Objective. The operatic singing technique is frequently used in classical music. Several acoustical parameters of this specific technique have been studied but how these parameters combine remains unclear. This study aims to further characterize the Western operatic singing technique by observing the effects of melody and technique on acoustical and musical parameters of the singing voice. Methods. Fifty professional singers performed two contrasting melodies (popular song and romantic melody) with two vocal techniques (with and without operatic singing technique). The common quality parameters (energy distribution, vibrato rate, and extent), perturbation parameters (standard deviation of the fundamental frequency, signal-to-noise ratio, jitter, and shimmer), and musical features (fundamental frequency of the starting note, average tempo, and sound pressure level) of the 200 sung performances were analyzed. Results. The results regarding the effect of melody and technique on the acoustical and musical parameters show that the choice of melody had a limited impact on the parameters observed, whereas a particular vocal profile appeared depending on the vocal technique used.Conclusions. This study confirms that vocal technique affects most of the parameters examined. In addition, the observation of quality, perturbation, and musical parameters contributes to a better understanding of the Western operatic singing technique.
