【摘要】：目的研究短音ABR對(duì)評(píng)估聽(tīng)閾的作用。方法采用特定參數(shù)的短音做為刺激音對(duì)20名正常人進(jìn)行了頻率特異性ABR檢查。觀察正常值特點(diǎn)及反應(yīng)閾與主觀聽(tīng)閾之間的差異。結(jié)果 20名聽(tīng)力正常人TP-ABR在4k Hz、2k Hz、1k Hz和0.5k Hz時(shí)100%可引出Ⅰ、Ⅲ、Ⅴ波。記錄Click-ABR與TP-ABR的Ⅰ、Ⅲ、Ⅴ潛伏期、反應(yīng)閾值。通過(guò)采用配對(duì)t檢驗(yàn)進(jìn)行統(tǒng)計(jì)學(xué)分析顯示:Clic k-ABR與4k Hz的TP-ABR在I、III、V波潛伏期上均無(wú)統(tǒng)計(jì)學(xué)差異;Click-ABR與2k Hz的TP-ABR在I波潛伏期上有統(tǒng)計(jì)學(xué)差異,與III、V波潛伏期無(wú)統(tǒng)計(jì)學(xué)差異。Click-ABR與1k Hz、0.5k Hz的TP-ABR在I、III、V波潛伏期上均有統(tǒng)計(jì)學(xué)差異。TP-ABR的主觀閾值與純音測(cè)聽(tīng)間差異無(wú)統(tǒng)計(jì)學(xué)意義。結(jié)論 TP-ABR各個(gè)頻率的聽(tīng)閾情況有一定差距。
[Abstract]:Objective to study the effect of short tone ABR on hearing threshold evaluation.Methods Frequency-specific ABR was performed in 20 normal subjects using short tone with specific parameters as stimulator.The characteristics of normal value and the difference between the reaction threshold and the subjective hearing threshold were observed.Results I, III and V waves could be induced by 100% of TP-ABR at 1kHz and 0.5kHz in 20 normal hearing persons.I, 鈪，
