How constant is subglottal pressure in singing?
نویسنده
چکیده
According to previous investigations by Leanderson, Sundberg, & von Euler, subglottal pressure in singing is adapted to pitch and loudness. Thus, wide musical intervals and great, sudden changes of loudness were found to be associated with substantial and precise pressure changes. In this study, we will focus on the significance to subglottal pressure of smaller, but equally important effects, namely those associated with musical expression, particularly alternations between stressed and unstressed syllables. We will use a GAELTEC pressure transducer introduced through the nose for measuring changes in subglottal pressure during vocal exercises and artistic performance of lieder and arias. Synchronous recordings are made of fundamental frequency and loudness. Professional singers will serve as subjects.

On the Quantitative Relationship between Subglottal Pressure, Vocal Cord Tension, and Glottal Adduction in Singing
The quantitative relationship between glottal flow parameters (fundamental frequency, average flow, peak flow etc.) and glottal control parameters (cord tension, glottal adduction, subglottal pressure) has been measured. Using the condition of constant glottal flow our model is able to produce the range of pitches of the modal tenor register. Increasing fundamental frequency is realized by incr...
متن کاملBreathing muscle activity and subglottal pressure dynamics in singing and speech
Previous studies have indicated that the diaphragm may contribute to the accomplishment of the quick and precise subglottal pressure changes required during singing. The present investigation compares data collected from simultaneously recorded EMG from breathing muscles and transdiaphragmatic pressure during singing as well as during nonsense and emphatic speech.
متن کاملBreathing behavior during singing
Together with Curt von Euler and the late Rolf Leanderson, the author has carried out a series of investigations of the breathing behavior during the last decade. This article presents the picture of phonatoy breathing in singing that has emerged from this research. Subglottal pressure is determined by muscular forces, elasticity forces, and gravitation. The phonatoy function of the breathing a...
متن کاملVoice source characteristics in six premier country singers.
Voice source characteristics as derived from inverse filtering were analyzed in 6 country singers' speech and singing. Results showed that the closed quotient varied systematically with vocal loudness, and that glottal compliance (the ratio between transglottal AC volume displacement and subglottal pressure) decreased with increases in fundamental frequency but remained unaffected by vocal loud...
متن کاملAerodynamic and acoustical measures of speech, operatic, and Broadway vocal styles in a professional female singer.
Understanding how the voice is used in different styles of singing is commonly based on intuitive descriptions offered by performers who are proficient in only one style. Such descriptions are debatable, lack reproducibility, and lack scientifically derived explanations of the characteristics. We undertook acoustic and aerodynamic analyses of a female subject with professional experience in bot...
