目的探讨正常人短增量敏感指数（SISI）与测试音听力级关系。方法试验频率用1kHz、2kHz和4kHz，从听阈上15dBSL和20dBSL开始，逐档递增强度10dB进行SISI，直至95dBHL时止。结果3个频率的SISI均随听力级的递增而增高，在65dBHL～95dBHL甚或更高的听力级容易达到SISI高得分。已显示出SISI与测试音听力级呈正相关。结论SISI高得分易于在高强度声刺激下出现，表明高强度测试音SISI试验是鉴别耳蜗性聋和蜗后聋的重要听力学检查法。
Objective To investigate the relationship between short Sense Sensitivity Index (SISI) and test tone level in normal subjects. Method The test frequency was 1 kHz, 2 kHz and 4 kHz, starting from the 15 dBSL and 20 dBSL on the hearing threshold, increasing the intensity by 10 dB for the SISI step by step until reaching 95 dBHL. Results The SISI of three frequencies increased with the hearing level, and the SISI score was easily reached at 65dBHL ~ 95dBHL or even higher hearing level. SISI has been shown to correlate positively with the test tone level. Conclusion The high SISI score tends to appear under high-intensity acoustic stimulation, indicating that high-intensity test-sound SISI test is an important audiological test to identify cochlear deafness and cochlear deafness.
