可听度对比阈值测试与噪声下言语测试的相关性研究OA

Objective To determine the correlation between the audible contrast threshold(ACT)test and speech in noise(SIN)test in patients with symmetrical moderate-to-severe and severe sensorineural hearing loss.Methods Eighty patients with moderately severe to severe bilateral symmetrical sensorineural hearing loss were recruited,while thirty randomly selected individuals with normal hearing and no other ear diseases served as the control group.All participants completed both the ACT test and SIN test.ACT values,signal-to-noise ratio loss (SNR-loss)values,SIN test duration,and ACT test duration were compared between the hearing loss group and the control group,and the correlation between SNR and ACT values were analyzed.Results Both ACT and SNR-loss values,SIN testing time and ACT testing time in the hearing loss group were higher than those in the control group(P<0.05).Both groups of ACT values increased with the increase in SNR-loss,showing statistically significant differences(P<0.05).Conclusions This study demonstrates that the ACT value is correlated with SNR-loss in the SIN test.Given that the ACT test can be completed in a shorter time and is not language dependent,it can serve as a reliable alternative to the SNR test.
