中文广东话版与普通话版噪声下言语测试材料的开发(英文)

Development of two versions of Chinese hearing in noise test: the Cantonese and mandarin hearing in noise test

开发两种中文版本的噪声下言语测试材料(hearinginnoisetest,HINT)–广东话版(Cantonesehearinginnoisetest,CHINT)和普通话版(Mandarinhearinginnoisetest,MHINT),用于评估讲广东话和普通话者的言语理解能力。共168名听力正常的受试者参与本研究,短句材料均选用日常用语。通过调整短句在噪声下的给声强度达到每个短句难度均等,得到每表20句音素平衡的句表。使用这些句表测试受试者的短句接受阈(ReceptionThresholdsforSentences,RTSs),RTSs定义为:短句重复的正确率为50%时的信噪比。受试者佩戴耳机分别在安静和三种噪声条件下—噪声在两侧、左侧和右侧进行测试。噪声固定在65dB(A),通过调整言语声强度来改变信噪比。句表间测试的可比性和同一句表重复测试的可靠性均非常高,表明使用任意句表均能得到一致的结果。同时得到了测试结果的置信区间,并将CHINT和MHINT的正常值与英文版进行了比较。

Two Chinese versions of the Hearing In Noise Test(HINT) were developed for assessing speech understanding ability of Cantonese and Mandarin speakers - the Cantonese Hearing In Noise Test (CHINT)and the Mandarin Hearing In Noise Test(MHINT)A total of 168 subjects with normal hearing . thresholds participated in the studies. Sentence materials that represent daily conversational speech were created and recorded. These sentences were equated for difficulty by adjusting their presentation levels in noise. Twelve 20-sentence lists with equal phonemic content were created. Using these lists,Reception Thresholds for Sentences(RTSs), defined as the signal-to-noise ratio at which sentences were repeated correctly 50 % of the time,were obtained. RTSs were measured under headphones in quiet and in three noise conditions. For the noise conditions,speech was presented from the front and noise was processed to simulate origination from the front,the right and the left. The noise was fixed at 65 Db(A)and the speech level was adjusted adaptively. Interlist or test-retest reliability was high,suggesting that consistent results can be obtained using any list. Confidence intervals were measured and reported. Norms obtained using the CHINT and MHINT are comparable to those for the English HINT. [
