Abstract:
Objective To investigate the differences in speech recognition in noise between patients with con-genital and acquired single-sided deafness.Methods Sixty-two patients with single-sided deafness were included in this study,which included 31 congenital single-sided deafness(CSSD)cases and 31 acquired single-sided deafness(ASSD)cases according to the onset of deafness.Thirty-one normal hearing(NH)subjects were also included in this study as the control group.The ability of speech recognition in noise were tested and compared among the three groups,meanwhile the differences between patients with left and right single-sided deafness were compared.Results The speech recognition threshold in noise of ASSD patients was significantly higher than that of CSSD patients,and both of them were significantly higher than that of the NH subjects.Under the 0 and-2 dB signal-to-noise ra-tio conditions,the speech recognition score was significantly lower in ASSD patients compared to CSSD patients,but only in ASSD patients it was significantly lower than that of the NH group,with no significant difference be-tween CSSD patients and the NH group.A significant difference in speech recognition thresholds was observed be-tween left and right CSSD patients.Conclusion CSSD have better speech recognition in noise than ASSD patients,suggesting better central function compensation.In addition,the side of deafness affects the speech recognition per-formance of CSSD patients.
