摘　　要：目的 本研究旨在开发与验证宁波方言版噪声下数字三联音测听(Digit Triplet Test,DTT)材料。方法选取以宁波方言为母语的成年女性诵读0~10共11个数字,经过编制与优化后形成宁波方言版噪声下DTT测听材料。对另外21名听力正常且以宁波方言为母语的青年人分别进行三联音识别率测试及自适应三联音测试,评估宁波方言版DTT的心理测量函数曲线和评估该测试在正常青年人中的测试信度。结果 11个数字全部被纳入到测听材料中,同时被组合成三联音测试项。拟合出的宁波方言版DTT的心理测量函数曲线的斜率为18.3%/dB,自适应模式下的言语识别阈值为-11.8±1.3 dB SNR,测量误差为0.6 dB。结论 本研究标准化开发的宁波方言版噪声下DTT有着良好心理测量函数曲线参数和复测信度。Objective The aim of this study was to develop and validate the Ningbo version of the Digit Triplet Test(DTT).Methods Digits from 0-10 were recorded by female adults who were native speakers of Ningbo dialect.Ningbo DTT materials were developed via optimization.The psychometric function of the Ningbo DTT was calculated and its test reliability was evaluated by 21 native speakers with normal hearing.Results After level correction,all 11 digits were included in the test material while being combined into triplet items.The slope of the fitted psychometric function curve for the Ningbo DTT was 18.3%/dB,and the speech recognition threshold on adaptive measurement was-11.8±1.3 dB SNR,with a measurement error of 0.6 dB.Conclusion The standardized Ningbo DTT developed in this study has good psychometric function parameters and test-retest reliability.
