摘要
目的观察连续用力吹气练习(SFBE)对正常人发音的即时影响。方法 43名健康成年人在SFBE前后分别进行3次最长时间的发/a/音,对录音文件进行声音参数分析,包括平均最长发声时间(MMPT)、发声平均频率(MF)和平均声级(MSPL)。结果 SFBE后,被试MMPT(P<0.01)和MSPL(P<0.001)明显提高,MF无显著性差异(P>0.05)。结论 SFBE可以提高健康成年人MMPT和MSPL,对MF无明显影响。
Objective To observe the immediate effects of the sustained forced-blowing exercise（SFBE） on the phonation function in young healthy people. Methods 43 young healthy people were asked to pronounce a longest /a/ in a comfortable situation within one breath for 3 times before and after SFBE. The sound files were analyzed with computer sound analysis system, with the parameters of mean maximum phonation time（MMPT）, mean frequency（MF） and mean sound pressure level（MSPL）. Results The MMPT and MSPL increased（P〈0.01） after SFBE. There was no significant difference in the MF（P〈0.05） before and after SFBE. Conclusion The SFBE can improve the MPT and MSPL of the healthy people obviously, without affections on the MF.
