초록

Purpose: The purpose of this study was to examine phonation threshold measures of Korean adults and examine their effects of age, gender, and speech stimulus. Methods: A total of 120 Korean adults (males 60, females 60) from the 20s to 50s participated in this study. For measuring phonation threshold measures, phonation threshold pressure (PTP) and phonation threshold flow (PTF) were measured using the Phonatory Aerodynamic System (PAS) Model 6600 (KayPENTAX Corp.) and phonation threshold power (PTW) was calculated from PTP and PTF. Results: The results showed that PTF and PTP values were significantly different according to gender (p < 0.05); significantly higher PTF and PTP values were revealed in males. On the other hand, PTW values were significantly different in age and gender (p < 0.05). Moreover, significant effect on speech stimulus (/pa/ vs. /pi/) was observed in PTP (p < 0.001) and PTW (p < 0.001). Higher PTP and PTW were estimated with /pi/. Conclusion: Accordingly, these results demonstrated PTF and PTP had a gender effect suggesting that phonation threshold related aerodynamic measures should take into consideration for gender. Additionally, PTP and PTW measures were also changed depend upon speech stimulus. Thus, speech stimulus also should be considered in measuring PTP and unified speech stimulus need to provide for evaluating aerodynamic measures more effectively in clinical practice.
