Abstract：Objective To assess the Ningbo Digit Triplet Test for hearing screening sensitivity and specificity,and to examine the impact of hearing threshold,education,age,and cognitive ability on the test.Methods 23 young normal-hearing native speakers of Ningbo dialect and Mandarin,and 33 older Ningbo dialect speakers were recruited.Young participants took the test in both dialects under noise,while older participants underwent pure tone tests,the dialect test,and cognitive assessments,with 10 also taking the Mandarin Digit Triplet Test.Results No significant SRT difference was found between dialects in young participants(P＞0.05),but a significant difference was found in older participants(P＜0.05).Education and age did not correlate significantly with dialect test SRTs.For screening at 25 dB HL,the optimal SRT cutoff was-7.7,with 0.870 sensitivity and 0.909 specificity.At 35 dB HL,the cutoff was-7.7,with 1 sensitivity and 0.975 specificity.Conclusion Older adults in Ningbo need dialect-based hearing screening tools.The Ningbo Digit Trip-let Test is promising for widespread screening in Ningbo,with a 35 dB HL screening target recommended.
