Study On The Influence Of Hearing Aids On SISI And UCL Values In Patients With Sensorineural Hearing Accompanied By Loudness Recruitment

Objective To investigate the impact of hearing aid intervention on sensorineural hearing loss(SNHL)patients with short-term sensitivity index(SISI)test and uncomfortable levels(UCL)test,Patients with moderate to severe SNHL in the revival phenomenon undergo adaptive training before and after the hearing aid is worn,whether the bare SISI value and UCL value are displaced,whether the auditory dynamic range is changed,and whether the hearing aid intervention is helpful to revive patients' loud tolerance.There is a certain reference value and guidance significance for hearing aid intervention and rehabilitation in patients with hearing loss.Methods 41 moderate to severe SNHL patients(79 ears,grouped by ear)were selected and classified as experimental group by 26 patients(49 ears)with re-vibration phenomenon in 1k Hz SISI test.There were 15 patients without regurgitation.30 ears were recorded as control group.UCL tests were performed on the two groups of patients and the UCL values of 0.5 k Hz,1 k Hz,and 2 k Hz were recorded for each group of subjects;after three months of hearing aid intervention under real ear analysis,the follow-up review was performed again.Ear 1k Hz SISI and UCL tests were performed using statistical software IBM SPSS Statistics 24 version software package to analyze the 1k Hz SISI,UCL values and auditory dynamic range changes in patients with moderate-to-severe SNHL who had re-evolution before and after hearing aid wearing.0.05 was considered statistically significant.Results 1.There was no significant difference in the 1k Hz SISI value between the experimental group and the control group before and after the hearing aid intervention(P>0.05).2.There was a significant difference in the 0.5k Hz,1k Hz,2k Hz UCL values and auditory dynamic range between the experimental group and the control group before hearing aid intervention(P<0.05).3.There was a significant difference in the 0.5k Hz,1k Hz,2k Hz UCL values and auditory dynamic range between the experimental group and the control group after hearing aid intervention(P<0.05).4.There was a significant difference in the auditory dynamic range between the 0.5k Hz,1k Hz,2k Hz UCL and the auditory dynamic range of the experimental group before and after the hearing aid intervention(P<0.05).5.Before and after the hearing aids intervention,there was no significant difference in the 0.5k Hz,1k Hz,2k Hz UCL,and the dynamic range of hearing between the control group and the control group(P>0.05).6.The differences between 0.5k Hz,1k Hz,and 2k Hz UCL difference between the experimental group and the control group before and after the hearing aid intervention were statistically significant(P<0.05).7.There was no significant difference in UCL values between 0.5k Hz,1k Hz and 2k Hz in the experimental group and the control group before and after the hearing aid intervention(P>0.05).Conclusion 1.Short incremental sensitivity index(SISI)test values are not affected by hearing aid intervention.2.The UCL value and the dynamic range of hearing in patients with moderate to severe SNHL were lower than those without SNHL.3.The UCL value and auditory dynamic range of patients with moderate to severe SNHL were influenced by hearing aids.The performance of hearing aids was adaptive to the hearing aids.The UCL value was increased and the dynamic range of hearing was widened..4.The UCL value and auditory dynamic range of SNHL patients without revitalization were less affected or not affected by the hearing aid intervention...
