To discriminate among degrees of auditory performance of the Digits-in-Noise (DIN) test.
We performed Pearson's correlations and age- and sex-adjusted linear regression models to examine the correlation between pure-tone average (PTA) from pure-tone audiometric tests and speech recognition thresholds (SRT) from the DIN test. Then, optimal SRT cut-points by PTA-defined hearing status (0-25 dB HL [normal], 26-40 dB HL [mild hearing loss], 41-50 dB HL [moderate hearing loss]) were compared across three methods: Youden, Nearest, and Liu. SRT-defined categories of auditory performance were compared to PTA-defined hearing categories to examine the convergence of similar categories. 3422 Rotterdam Study participants aged 51-98 years between 2011 and 2014.
The correlation between SRT and PTA was 0.65 (95% Confidence Interval: 0.63, 0.67) in the overall sample. The variability of SRT explained by PTA after age and sex adjustment was 54%. Optimal cut-points for the overall sample across the three methods were: ≤ -5.55 dB SNR (normal); > -5.55 to ≤ -3.80 dB SNR (insufficient performance); > -3.80 dB SNR (poor performance). When comparing the SRT- or PTA-defined categories, 59.8% had concordant hearing categories and 40.2% had discordant hearing categories.
Discrimination of degrees of auditory performance may add greater utility of the DIN test.
区分噪声中数字（DIN）测试的不同听觉表现程度。
我们进行了Pearson相关性分析以及年龄和性别调整后的线性回归模型，以检验纯音听力测试中的纯音平均听阈（PTA）与DIN测试中的言语识别阈（SRT）之间的相关性。然后，通过三种方法（约登法、最近邻法和刘法）比较了按PTA定义的听力状况（0 - 25 dB HL[正常]、26 - 40 dB HL[轻度听力损失]、41 - 50 dB HL[中度听力损失]）确定的最佳SRT切点。将SRT定义的听觉表现类别与PTA定义的听力类别进行比较，以检验相似类别的一致性。研究对象为2011年至2014年间年龄在51 - 98岁的3422名鹿特丹研究参与者。
在总体样本中，SRT与PTA的相关性为0.65（95%置信区间：0.63，0.67）。年龄和性别调整后，PTA解释的SRT变异性为54%。三种方法在总体样本中的最佳切点为：≤ -5.55 dB SNR（正常）；> -5.55至≤ -3.80 dB SNR（表现不足）；> -3.80 dB SNR（表现差）。比较SRT或PTA定义的类别时，59.8%的听力类别一致，40.2%的听力类别不一致。
区分听觉表现程度可能会增加DIN测试的实用性。
