Abstract:
Objective To analyze the test results of persons with noise -induced hearing loss using disyllabic Mandarin speech test materials (MSTMs) .Methods 57 subjects with noise -induced hearing loss (noise group) were divided into three groups according to the duration of noise exposure :less than 10 years ,between 11 and 20 years and more than 20 years ,and also separated into 2 groups in terms of the degrees of hearing loss (group A :pure tone average thresholds of 0 .5 ,1 ,2 ,and 4 kHz less than or equal to 30 dB HL ,group B:pure tone average threshold of 0 .5 ,1 ,2 ,and 4 kHz greater than 30 dB HL) .66 subjects with normal hearing were in the control group .All the subjects enrolled in this study could speak Mandarin well in their daily life .Nine lists of disyllabic Mandarin speech test materials were utilized to test SRT and P -I function for these groups respectively .Results PTA and SRT in the noise group were much higher than the control group ,the average slope of P -I function was 5 .94% /dB ,and the curve of P-I function moved to the right side .SRT showed obvious changes as the increase of the years of noise exposure and especially in the group which had more than 20 years noise exposure (P<0 .01) . SRT of group B which had more hearing loss were greater than that of group A (P<0 .01) .Conclusion SRTs in the noise group are much higher than the control group with the average slope of P -I functions decreasing and the curve moving to the right side .As the years of noise exposure increase and the degrees of hearing loss become more severe ,SRT rise more apparently .
