作者们用一种视-听测试方法对听力障碍进行定量检查。这种方法基本上仍属于语言测听法,所不同的是:(1)测试信号是提要求或提问题的句子,而不是用单音节词;(2)作为测试信号的主句和干扰句子分别从两个扬声器同时播放,主句与干扰句之间的各种音量比率称为MCR(message-to-competition ratio);(3)在受试者通过听觉作出行为反应后,再通过电视屏幕播放相同内容的测试主句,要求受试者作出相应的行为反应。
The authors used a visual-audiometric test to quantify hearing impairment. This method basically still belongs to the language audiometry, the difference is: (1) the test signal is to mention or ask questions sentence, rather than monosyllabic words; (2) as the main signal of the test signal and interfere with the sentence Respectively, from the two speakers at the same time play, the main sentence and the interference between the various volume ratio is called the MCR (message-to-competition ratio); (3) in the subject through auditory reaction to behavior, and then through the TV screen Play the same test main clause, require subjects to make the appropriate behavioral response.
