本研究的目的是调查10名听力正常的成年男性，10名听力受损的成年男性谁表现出可理解的语言，和10名听力受损的成年男性与半可理解的语言所产生的爆破辅音的口腔气流的速率。在由元音/a/和/i/以及辅音/B/、/p/、/d/和/t/组成的CV和VCV音节的产生期间测量口腔气流的峰值速率。在一般情况下，结果表明，一个显着的有声/无声的区别，为气流的速度，发生正常听力和可理解的听力受损的科目，但不为半可理解的科目。此外，半可理解的听力受损，在CV的上下文中，产生有声的爆破音与显着更大的空气流量和无声的爆破音与显着更少的空气流量;和，产生有声和无声的爆破音，在VCV的上下文中，与显着更少的空气流量相比，听力正常和可理解的听力受损的扬声器。
The purpose of this study was to investigate the rate of oral air flow for plosive consonants produced by 10 normal hearing adult males, 10 hearing-impaired adult males who demonstrated intelligible speech, and 10 hearing-impaired adult males with semi-intelligible speech. The peak rate of oral air flow was measured during production of CV and VCV syllables consisting of the vowels /a/ and /i/ and the consonants /b/, /p/, /d/, and /t/. In general, the results indicated that a significant voiced/voiceless distinction, for rate of air flow, occurred for the normally hearing and intelligible hearing-impaired subjects but not for the semi-intelligible subjects. In addition, the semi-intelligible hearing impaired, in the CV context, produced voiced plosives with significantly greater air flow and voiceless plosives with significantly less air flow; and, produced both voiced and voiceless plosives, in the VCV context, with significantly less air flow, when compared with the normally hearing and intelligible hearing-impaired speakers.
