目的
在这项研究中，作者的目的是开发一个视觉模拟的广泛使用的语音接收阈值（SRT; R。Plomp & A. M. Mimpen，1979 b）测试。文本接收阈值（TRT）测试，其中视觉呈现的句子被掩盖的酒吧模式，使模态特异性方差在噪声中的语音理解的量化，以获得更多的洞察个体间的差异，在这种能力。
方法
使用类似于SRT测试的自适应程序，TRT测试确定正确阅读50%句子所需的未屏蔽文本的百分比。对34名年龄在19 ~ 78岁、听力正常的受试者进行了稳态噪声（SRT（STAT））、调制噪声（SRT（MOD））和TRT测定。
结果
结果表明，SRT（STAT）和SRT（MOD）的方差中约有30%与TRT的方差共享，这反映了非情态特定的认知或语言能力在形成句子片段的有意义整体中的共享参与。
结论
TRT测试是SRT测试的视觉模拟，已被开发用于测量与模态特异性认知技能相关的噪声中言语理解的方差。在未来的研究中，TRT试验的规范性数据应开发。测量在理解言语方面有困难的个人的TRT也是有趣的。
PURPOSE
In this study, the authors aimed to develop a visual analogue of the widely used Speech Reception Threshold (SRT; R. Plomp & A. M. Mimpen, 1979b) test. The Text Reception Threshold (TRT) test, in which visually presented sentences are masked by a bar pattern, enables the quantification of modality-aspecific variance in speech-in-noise comprehension to obtain more insight into interindividual differences in this ability.
METHOD
Using an adaptive procedure similar to the SRT test, the TRT test determines the percentage of unmasked text needed to read 50% of sentences correctly. SRTs in stationary noise (SRT(STAT)), modulated noise (SRT(MOD)), and TRTs were determined for 34 participants with normal hearing, aged 19 to 78 years.
RESULTS
The results indicate that about 30% of the variance in SRT(STAT) and SRT(MOD) is shared with variance in TRT, which reflects the shared involvement of a modality-aspecific cognitive or linguistic ability in forming meaningful wholes of fragments of sentences.
CONCLUSION
The TRT test, a visual analogue of the SRT test, has been developed to measure the variance in speech-in-noise comprehension associated with modality-aspecific cognitive skills. In future research, normative data of the TRT test should be developed. It would also be interesting to measure TRTs of individuals experiencing difficulties understanding speech.
