目标。编制两个版本的普通话听力噪声测试(MHINT)。这些测试是适应性测试，测量安静和噪声中句子的接收阈值(RTS)。设计：(1)开发句子材料，(2)均衡句子难度，(3)创建语音平衡的句子列表，(4)评估列表内的反应可变性，列表间的可靠性，并产生标准化数据。共有137名大陆母语为普通话(普通话)的受试者中国和89名台湾母语为普通话的受试者参加。他们的听力阈值在25dBHL或更高。RTS是在四种耳机测试条件下测量的：安静和噪声来自0度(噪声前面)、向右90度(噪声右侧)和左侧90度(噪声左侧)的噪声。在任何情况下，语音都是从前方(0度)发出的。噪声水平固定在65dBA，并自适应地改变语音以获得RTS。两个版本的测试材料，包括大陆普通话(MHE4T-M)和台湾普通话方言(MHINT-T)的24，20个句子列表，由两组240个句子组成，每句10个音节。使用MHINT-M的平均安静RTS为14.7dBA，使用MHlNT-T的平均安静RTS为19.4dBA。使用MHINT-M，噪声前沿的平均RTS为-4.3分贝信噪比(SNR)，右噪声为-11.7分贝信噪比，左噪声为-11.7分贝信噪比。使用MHINT-T，噪声前RTS为-4.0 dBSNR，右噪声为-10.7 dBSNR，左噪声为-11.0 dBSNR。噪音测试的结果略好于英语提示标准。列表内的回答变异性低，列表间的可靠性高，表明使用任何列表都可以获得一致的结果。结论：MHINT的两个版本是首个标准化的普通话句子语音清晰度测试。与提示的其他语言版本类似，MHINT是使用与英语提示相同的原理开发的，允许将MHINT的常模参考结果直接与其他语言的结果进行比较。MHINT将受益于对其有效性的进一步评估。
Objective. To develop two versions of the Mandarin Hearing In Noise Test (MHINT). These tests are adaptive tests that measure the reception threshold for sentences (RTSs) in quiet and in noise. The RTS is the presentation level at which half the sentences are correctly recognized.Design: Four studies were undertaken to (1) develop sentence materials, (2) equalize sentence difficulty, (3) create phonemically balanced sentence lists; and (4) evaluate within-list response variability, inter-list reliability, and produce normative data. A total of 137 native Mandarin (Putonghua) speaking subjects in Mainland China and 89 native Mandarin speakers in Taiwan participated. They had normal hearing thresholds at 25 dB HL or better. RTSs were measured under four headphone test conditions: Quiet, and in noise with noise originating from the 0 degree (Noise Front), 90 degrees to the right (Noise Right), and 90 degrees to the left (Noise Left). The speech originated from the front (0 degree) in all conditions. The noise level was fixed at 65 dBA, and the speech was varied adaptively to find the RTS.Results. Two versions of the test materials, consisting of 24,20-sentence lists each in Mandarin spoken in the Mainland (the MHE4T-M) and the dialect of Mandarin spoken in Taiwan (the MHINT-T), were created from two sets of 240 sentences containing 10 syllables per sentence. The mean Quiet RTS was 14.7 dBA, using the MHINT-M, and 19.4 dBA, using the MHlNT-T. Using the MHINT-M, the mean RTS for Noise Front was -4.3 dB signal-to-noise ratio (SNR), -11.7 dB SNR for Noise Right, and -11.7 dB SNR for Noise Left. Using the MHINT-T, the Noise Front RTS was -4.0 dB SNR, -10.7 dB SNR for Noise Right, and -11.0 dB SNR for Noise Left. Results in noise are slightly better than those seen for the English HINT norms. Response variability within list was low, and inter-list reliability was high, indicating that consistent results can be obtained using any list. Confidence intervals are reported.Conclusions: The two versions of the MHINT are the first standardized Mandarin sentence speech intelligibility tests. Similar to other language versions of the HINT, the MHINT was developed using the same rationale as the English HINT, allowing norm-referenced results for the MHINT to be compared directly with results in other languages. The MHINT would benefit from further evaluation of its validity.
