言语测听在神经听力学评价方面两个取得显著进展的诊断方法是:强度—可懂度(PI)函数及信息—竞争比(MCR)函数的判定,在近十年中,成为检出成年人蜗后病变的主要手段。本文旨在研究:1。儿童言语可懂度(PSI)试验对儿童的中枢性听力障碍是否灵敏和指征的可靠性;2.PSI试验结果是否象应用于成人那样用于儿童。PSI试验包括PI函数及MCR函数两项诊断步骤,由于儿童在接受语言能力方面有发育上的差别,因此,在儿童必须用不同于成人的试验材料,以求尽量减小儿童接受语言能力对PSI结果的影响。
Speech audiometry Two diagnostic methods that have made significant progress in the evaluation of neurological audiology include the determination of the intensity-readability (PI) function and the information-competition ratio (MCR) function, and the detection of adults in the past decade People after the main means of cochlear lesions. This article aims to study: 1. Whether the PSI test is sensitive and indicative of the reliability of central hearing impairment in children; 2. Whether the PSI test results are intended for children as they are for adults. The PSI test includes two diagnostic steps, the PI function and the MCR function. Since children have a developmental difference in their ability to accept speech, children must use test materials different from those of adults in order to minimize the children’s ability to accept language proficiency in PSI Effect of the result.
