The aims of this study were to prepare a Persian version of the temporal resolution test using the method of Phillips et al (1994) and Stuart and Phillips (1996), and to compare the word-recognition performance in the presence of continuous and interrupted noise as well as the temporal resolution abilities between monolingual (ML) Persian and bilingual (BL) Turkish-Persian young adults.
Word-recognition scores (WRSs) were obtained in quiet and in the presence of background competing continuous and interrupted noise at signal-to-noise ratios (SNRs) of -20, -10, 0, and 10 dB.
Two groups of 33 ML Persian and 36 BL Turkish-Persian volunteers participated.
WRSs significantly differed between ML and BL subjects at four sensation levels in the presence of continuous and interrupted noise. However, the difference in the release from masking between ML and BL subjects was not significant at the studied SNRs.
BL Turkish-Persian listeners seem to show poorer performance when responding to Persian words in continuous and interrupted noise. However, bilingualism may not affect auditory temporal resolution ability.
本研究旨在采用 Phillips 等人（1994 年）和 Stuart 和 Phillips（1996 年）的方法，编制波斯语版时间分辨率测试，并比较单语（ML）波斯语和双语（BL）土耳其语-波斯语年轻成年人在连续和间断噪声存在下的单词识别性能以及时间分辨率能力。
在信噪比（SNR）为-20、-10、0 和 10dB 的情况下，在安静和存在背景连续和间断噪声的情况下，获得单词识别得分（WRS）。
两组 33 名 ML 波斯语和 36 名 BL 土耳其语-波斯语志愿者参加了研究。
在四种感觉水平下，连续噪声和间断噪声存在时，ML 和 BL 受试者的 WRS 显著不同。然而，在研究的 SNR 下，ML 和 BL 受试者的掩蔽释放差异不显著。
BL 土耳其语-波斯语听众在连续和间断噪声中对波斯语单词做出反应时，表现似乎较差。然而，双语能力可能不会影响听觉时间分辨率能力。
