List Equivalency Of Speech Audiometry (BKB-SIN) In Mandarin

Objective:The purpose of this study was to evaluate the equivalence of 16 Mandarin BKB-SIN speech tests in patients with hearing loss-sensitive patients,for better application in clinical practice.Methods:The test materials used in this study were selected from the Mandarin version of the Noise Under Speech Recognition Test Material(BKB-SIN)compiled by the General Hospital of the Chinese People's Liberation Army(301 Hospital).The test material contained 20 sentence tables(16 formal forms,4 predictions).Thirty-two subjects with moderate or severe sensorineural hearing loss were selected and tested in a standard soundproof room in strict accordance with the requirements of speech listening.The signal-to-noise ratio(SNR)and deviation ratio signal-to-noise ratio was calculated and analyzed with one-way ANOVA.If the tables are not all equal,cluster analysis is used to classify the tables with similar degrees of difficulty into one category and then analyze them.Results:The mean SNR of 32 Sensorineural hearing loss people was(2.49±2.49)dB,and the deviation ratio SNR was(0.21±1.67)dB.One-way analysis of variance(ANOVA)was performed on 32 patients with sensorineural hearing loss in 16 forms.Incomplete tableswere equivalent(F=8.7,P<0.001).Based on the degree of difficulty in the 16 tables,cluster analysis was used.Table 1-13 shows that the average SNR from the average deviation is-1.30 dB.Table 14-16 shows the average signal-to-noise ratio from the mean deviation.0.31 dB,Table 14-16 is easier than the rest of the table.Conclusion:The set of speech audiometry materials(BKB-SIN)is suitable for The assessment of hearing impairment of sensorineural hearing loss.
