摘要【Abstract】 Objective To study the value and significance of short increment sensitivity index (SISI) and transient evoked otoacoustic emissions (TEOAE) in the hearing screening of noise induced deafness with normal pure tone hearing threshold. Methods Fifty young adults with normal pure tone bearing threshold and a history of noise exposure participated in the study, in addition fifty subjects without noise exposure were included as the control group. The average age of the experimental group and the control group were 19.58±1.03 and 19.90±1.20 years old, respectively. Pure tone audiometry, SISI and TEOAE were performed. Statistical analysis was performed to analyze differences between two groups. Results The pure tone hearing thresholds from 0.25 kHz to 8 kHz in control group and noise group were less than 20 dB HL. No significant differences were found (P>0.05). The SISI of noise group were higher than that of normal group, and significant differences were found (P<0.01).The total correlation rate of TEOAE waveform in noise group and control group was 92.32%±1.99% and 97.92%士0.49%，respectively (P<0.05).The response intensity in noise group and control group was 16. 00±1.04 dB SPL and 20. 27±0. 70 dB SPL (P<0.05).The overall SNR in the noise group and control group was 12.66±1.55 dB and 20.95±0.89 dB, respectively (P<0.01). SISI of 6 kHz was negative correlated with TEOAE 3.5~4.5 kHz SNR(P<0.05).Conclusion High frequency SISI combined with TEOAE of higher screening standards can provide an early diagnosis strategy for noise-induced deafness.
