Аннотация
Voice aerodynamic analysis, including average glottal airflow rate, subglottal pressure level, glottal resistance and glottal efficiency can now be easily recorded by noninvasive methods. However, normative data are lacking for many populations. This study analyzed the characteristics of voice aerodynamic data in 90 healthy Taiwanese subjects aged 20 to 49 years. The average glottal airflow rate was greater for males than for females. Conversely, the value of glottal resistance was greater for females than for males. No significant differences were found in subglottal pressure and glottic efficiency between females and males. Stratification for age revealed no obvious influence on these parameters. This study found substantial inter-subject variations for derived glottal efficiency and glottal resistance, which may limit their potential application in clinical assessment.
