摘要
本研究采用了两个三因素混合实验设计,探讨了健听青年人在助听效果模拟和主频特征模拟两种听觉障碍模拟状态下塞音音节的识别特征。研究结果表明:(1)在助听效果模拟状态下,健听青年人塞音音节的识别率随音频感受范围的扩大而提高,但其识别率远低于理想状态的言语识别率;(2)在250-2000Hz及以上助听效果模拟中,含k的音节识别率显著高于含p和t的音节识别率;(3)在主频特征模拟状态下,健听青年人塞音音节识别率在1000-2000Hz频段最高,2000-3000Hz其次;(4)不同主频特征模拟频段送气塞音间的差异不同;(5)无论是在助听效果模拟还是主频特征模拟状态下,性别无显著差异。
Abstract This study, through two three-factor mixed experiments, aims to explore the characteristics of plosive syllable recognition by young people with normal hearing in the state of hearing aid effect simulation or main frequency simulation. The results show the following： 1） In the state of hearing aid effect simulation, the young people＇ s recognition rate of plosive syllables is raised with the expansion of the scope of audio frequency, though at a level lower than an ideal recognition rate. 2） In 250-2000Hz or above, the rate of the recognition of the plosive k in the state of hearing aid effect simulation is significantly higher than that of p or t. 3） In the state of main frequency simulation, the young people＇ s recognition rate of plosive syllables is the highest in 1000-2000Hz, followed hy 2000-d300Hz. 4） The recognition rate varies according to different frequency bands in the state of main frequency simulation. 5） There is no significant gender difference, whether in the state of hearing aid effect simulation or in the state of main frequency stimulation.
