目的：探讨正常成年人发不同元音时口腔压力和鼻流量值的差异，并分析二者之间是否有相关性。方法对30例正常成人（男女各半）在发／pa／、／pi／、／pu／时测量其口腔压力，在发／a／、／i／、／u／时测量其鼻流量，对结果进行统计学分析。结果①男性发／pa／、／pi／、／pu／时口腔压力平均值分别为4．53±0．70、5．21±0．80、5．87±1．45cmH2O，女性分别为4．09±0．30、4．47±0．30、4．77±0．32cmH2O，男性较女性高（P＜0．05）；不同元音间口腔压力值差异有统计学意义（P＜0．05），但不同性别和不同元音间无交互作用。②男性发／a／、／i／、／u／时鼻流量平均值分别为30．2％±5．75％、38．8％±8．54％、26．5％±6．03％，女性分别为32．4％±7．14％、40．5％±11．8％、30．1％±4．83％；女性较男性高，但差异无统计学意义（ P＞0．05），不同元音间鼻流量后差异有统计学意义（ P＜0．05），但不同性别和不同元音间无交互作用。③口腔压力和鼻流量值呈弱相关（ r＝－0．240）。结论不同性别成人发相同元音时，男性的平均口腔压力值较女性高，但男女之间鼻流量值差异无统计学意义；相同性别不同元音间口腔压力和鼻流量值差异有统计学意义；口腔压力与鼻流量弱相关。%Objective To investigate the difference and the correlation of the vowel's phonation threshold pressure and nasalance in normal subjects .Methods The Aeroview (GLOTTAL Enterprises)with the materials /pa/,/pi/,/pu/ was used to obtain phonation threshold pressure values and The NasalviewTM (Tiger Electronics Inc .,Seattle ,Shanghai) with the materials /a/,/i/,/u/was used to obtain nasalance values .A total of 30 subjects (15 males ,15 females ,and aged 19~30) years old received the tests .The results of the vowel's phonation threshold pressure and nasalance gender score difference were compared .Results The PTP gender scores of /a/,/i/,/u/in maleswere4.53±0.70cm,5.21±0.80cm,5.87±1.45cm,andinfemaleswere4.09±0.30cm,4.47±0.30cm, and 4 .77 ± 0 .32 cm ,respectively .There were significant differences between males and females in PTP values (P<0 .05) .The PTP gender score differences showed that males were greater than that of females .There were signifi‐cant differences in different vowels (P<0 .05) .The nasalance gender scores of /a/,/i/,/u/in males were 30 .2 ± 5 . 75% ,38 .8 ± 8 .54% ,26 .5 ± 6 .03% ,and in females w ere32 .4 ± 7 .14% ,40 .5 ± 11 .8% ,and 30 .1 ± 4 .83% ,respec‐tively .There were no significant differences between males and females in nasalance values (P> 0 .05) .The na‐salance gender score differences showed that females were greater than males .There were significant differences in different vowels(P<0 .05) .This study found a weak correlation between PTP and nasalance .Conclusion The relationship between oral pressure and nasal flow cannot be accurately measured by measuring PTP ,and /pa/is a relatively suit‐able material for testing oral pressure .
